Putting On and Removing Tefillin

From Halachipedia

Putting on Tefillin at Home

  1. One who is careful to wear a Tallit Katan (Tzitzit) should put on the Tallit Katan and Tefillin in their house and then walk to Shul wearing Tefillin, in Shul they should then put on a Tallit Gadol. [1] However, some say that one should only put on one's Tefillin at home if one has worn the Tallit Gadol beforehand. [2]
  2. If one will have to pass dirty areas or there are goyim between one’s house and the Shul, one should put on the Tefillin in the hallway next to the Shul itself if possible. [3]
  3. Because the primary concern is only to enter Shul wearing Tefillin, one should leave the Tefillin outside Shul from the day before, to be able to put them on outside and enter the Shul wearing them. [4]
  4. Some say that one should also walk out of Shul wearing Tefillin. [5]
  5. Some say it is preferable to put on Tefillin outside of Shul even if one will not be one of the first ten in the minyan because of it. [6]

When to Put on Tefillin

  1. The earliest time to put on Tefillin is the time of MeSheyakir. [7]
  2. The minhag is to put on Tefillin after having said Birchot HaShachar and Birchot HaTorah but preferably before the Shema in Korbanot and at least before Parshat HaTamid. [8]
  3. One may not put on Tefillin at night. [9] If one has not put on one's Tefillin, one still may do so during the time of bein hashemashot even though generally it is forbidden to wear them at night, as long as one has not recited arvit it is permissible bedieved. [10]
  4. Some have the minhag to keep their Tefillin on when attending a brit milah [11] while some people remove it before the brit. [12]
  5. One may put on Tefillin during the day, but not during the night. [13] One may put them on in the morning from the time of MeSheyakir. [14]
  6. Nowadays the prevailing custom is to lay them only during the weekday morning service. [15]
  7. The minimum requirement is to have Tefillin on during Kriyat Shema and Shemoneh Esrei. [16]
  8. The problem with wearing them all day is the necessity to remove them when encountering an unclean place and the requirement to constantly be aware of the fact they are being worn.
  9. If one has a choice between praying the Amida with the tzibbur or waiting for a pair of Tefillin one should wait for the Tefillin and pray alone unless due to waiting one would miss the time for praying. [17]
  10. If one is waiting for a pair of Tefillin and the time to say Keriat Shema may pass, one should recite Shema without Tefillin. [18]
  11. When one says "Vekeshartem LeOt Al Yadecha" one should touch one's Tefillin shel yad and when one says "VeHayu VeTotafot Ben Aynecha" one should touch one's Tefillin shel rosh. [19]
  12. Some have the minhag to touch their Tefillin when they say the following prayers: Oter Yisrael BeTifara (Tefillin shel rosh only), Ozer Yisrael BeGevura (Tefillin shel yad only), Kadesh Li Kol Bechor, at the words Yehe Kavod and Maasbeha Lechol Chay Ratzon in Hodu, Kadosh Kadosh Kadosh in Birkat Yotzer, Hashem Sifatay Tiftach, Hamivarech Et Amo BaShalom. [20]
  13. If it is after sunset but before tzet hakochavim and one has not yet put on Tefillin, one still may do so. [21] Once tzet hakochavim passes one may no longer do so. [22]

Tallit before Tefillin

  1. One should put on the Tallit before putting on one's Tefillin.[23] Even if the Tallit is only obligated in Tzitzit derabbanan, it still takes precedence over the Tefillin. [24]
  2. If one puts one's Tallit and Tefillin in the same bag, one should be careful to place the Tallit to the side of the Tefillin so that one can unpack the Tallit before the Tefillin. [25]
  3. If one is not going to fulfill the mitzvot of Tallit, one may pass over the Tefillin and take the Tallit or the other way around; pass over the Tallit. [26]Hence if the Tefillin was mistakenly placed above the Tallit and one did not plan on fulfilling the mitzvah with either for that moment, one may remove both and rearrange them. [27]
  4. Similarly, if one has a Tallit of Shabbat in the same bag and above the Tallit of the weekday one may take the Tallit of the weekday even if it is below the other Shabbat one. [28]
  5. If one has only Tefillin but not a Tallit, according to Ashkenazim one should not wait but rather one can just put on the Tefillin. Sephardim hold that if one will have the possibility of attaining a Tallit before the latest time to say Shema, one should wait to get the Tallit before putting on the Tefillin. However, if one will not have a Tallit available before the latest time for Shema, one should don the Tefillin in order to say Shema with Tefillin within the time. [29]
  6. If one takes off one’s Tallit and Tefillin momentarily and then puts them back on, one should still be careful to put on the Tallit first. [30]
  7. If one is wearing Tefillin and then a Tallit becomes available, one need not remove one’s Tefillin, rather one should just put on the Tallit while wearing the Tefillin. [31]
  8. If someone by accident took the Tefillin before the Tallit, some say that one should put on the Tefillin since one already has them in one’s hands, while others hold one should leave the Tefillin (respectfully), engage oneself in another activity and when one returns one can put on the Tallit first. [32]
    1. The same applies if one only picked up the Tefillin in their bag before taking the Tallit. [33]
    2. If there are Tefillin in the room that one is in and there is a Tallit in the next room, the principle of not passing up the mitzvah applies and so one should put on the Tefillin first or leave the Tefillin, engage in another activity and then get the Tallit first. [34]
  9. If one first made a mistake by taking the Tefillin and then made another mistake by putting down the Tefillin, one should put on the Tallit first, since one has already put the Tefillin down. [35]
  10. There is a doubt regarding a situation where one would be embarrassed to put on Tefillin without a Tallit, as to whether one can put on the Tallit first. [36]
  11. If one can only afford either a Tallit or Tefillin, one should buy Tefillin. [37]

Kavana when Putting on Tefillin

  1. When putting on Tefillin one should have the following kavana (intent): "Hashem commended us to wear these 4 parshiot (in the Tefllin) which speak of the oneness of Hashem and exodus of Egypt in order that we remember the miracles that reflect Hashem’s total control over the upper and lower worlds." One should also have intent to make one’s Nishama in one’s brain and the heart which is the seat of emotion and thought, subservient to Hashem, and in this way one will remember Hashem and minimize one’s personal pleasures. [38]
  2. It is very important to have said kavana, however in the case where one did not have such intent one has still fulfilled one's obligation, bediavad. [39]
  3. It is also important to have intent that one is doing the mitzvah in order to fulfill a biblical obligation. [40]

Process of Putting Tefillin On

  1. First one puts on the Tefillin of the arm before putting on the Tefillin of the head. [41] Therefore one should be careful to arrange the Tefillin in the case so that one takes the Tefillin shel yad first. Furthermore, it is proper to keep the Tefillin shel rosh in one's bag or at least still wrapped until one is finished donning the Tefillin shel yad. [42]
  2. Right handed people wear the Tefillin on their left arm and left handed people place it on their right arm. Whether you are right handed or left handed is determined by which hand you write with. Someone who is completely ambidextrous should place it on the left arm. [43] One who in the past performed all activities with his right hand but for whatever reason has lost use of it and now his left becomes stronger should place it on the right arm. [44]
  3. The Sephardic minhag is to place the Tefillin shel yad while seated and the Tefillin shel rosh while standing, [45] and remain standing while wrapping the Tefillin around the hand. [46] A Sephardi who prays in an Ashkenazic minyan should place his Tefillin according to Sephardic minhag. [47]
  4. According to some poskim one may kiss one's Tefillin shel rosh when one takes them out of one's bag even though one should try not to interrupt between the Tefillin shel yad and shel, rosh since kissing it is giving it honor, it is permitted. [48]
  5. Sephardim have the custom to recite the passages of "kadesh li" and vihaya ki yiveacha," two of the four passages in Tefillin after putting them on. [49]
  6. The bracha of shehecheyanu is not recited the first time someone puts on Tefillin. [50]
  7. If one injured one's arm, one should wrap one's Tefillin on top of the rag that covers the wound. [51] Nonetheless, one should try to avoid wrapping one's Tefillin over one's bandage. [52] Furthermore, in a case where donning the Tefillin over a rag is necessary, one does not recite a bracha on the Tefillin shel yad, but one should recite a bracha on the Tefillin shel rosh and have the Tefillin shel yad in mind. [53]

If One Mistakenly Put on the Tefillin Shel Rosh First

  1. If one mistakenly took the Tefillin shel rosh first, one must put it down and put on the Tefillin Shel Yad first. [54]
  2. If one mistakenly put on the Tefillin shel rosh first, one should put on the Tefillin shel yad afterwards and need not take off the Tefillin shel rosh before putting the Tefillin shel yad on. However, if one put the Tefillin shel rosh on incorrectly, one should take it off, put on the Tefillin shel yad, and then re-don the Tefillin shel rosh. [55]

If one only has one of the Tefillin

  1. If one only has one of the Tefillin he should wear it and say the beracha, similarly, if one of his Tefillin are pasul he should still wear the other and recite the beracha on it. [56]

Brachot of Tefillin

  1. Before the strap of the arm Tefillin is tightened, the blessing of להניח תפילין is said. [57] If someone forgot to recite the blessing before tightening the arm Tefillin he should still recite it, even if he has already placed his head Tefillin. [58]
  2. Upon placement of the head-tefillin, Sephardic and Hasidic authorities are of the opinion that the blessing on laying the head Tefillin is not necessary and the one blessing on laying the arm Tefillin is sufficient. [59] Ashkenazim do recite a second blessing of על מצות תפילין on the head Tefillin, before tightening it around the head‏. [60] It is also customary to add the phrase ברוך שם כבוד מלכותו לעולם וע‏ד because of the doubt as too the necessity of the bracha. [61]
  3. It is strictly forbidden to talk between the placement of the arm and head Tefillin. [62] Furthermore, one should not answer Kaddish or Kedusha between putting on Tefillin shel yad and Tefillin shel rosh, yet one should pause to listen to Kaddish or Kedusha.[63] If he mistakenly answered he does not recite a beracha on the head Tefillin. [64] One should not answer "amen" to another's beracha between donning the Tefillin shel yad and Tefillin shel rosh. [65] Nevertheless, if one accidentally answered "amen" to another's beracha, he does not make a beracha on the Tefillin shel rosh. [66]
  4. However, if one spoke by mistake about things unrelated to the Tefillin, he must recite the beracha of al mitzvat Tefillin as the Ashkenaz. [67] If he mistakenly spoke about things related to the Tefillin he not need to recite another beracha. [68]
  5. If one removes his Tefillin to go to the bathroom he recites a new beracha upon putting them back on. [69]
  6. It is prohibited to recite a bracha on stolen Tefillin, including Tefillin that one bought from a thief. [70]
  7. If one removes his Tefillin and puts on a different pair, he recites a beracha upon donning the other pair. [71]
  8. If one removed his Tefillin without the intention of putting them back on and then decides to put them back on, he recites another beracha when putting them back on. However, if one removed his Tefillin with the intention of putting them back, he does not recites another beracha when putting them back on. [72]
  9. After putting on Tefillin, there is a minhag to recite the parshiot of Vehaya Ki Yivecha and Kadish Li since they appear in the Tefillin.[73] While some say that one does not need to recite them, it is proper to say them. [74]

Where the Tefillin are placed

  1. The arm Tefillin is placed on the biceps of the arm, two finger breadths away from the elbow, with the box facing inward towards the heart. [75] After the beracha is said, the arm Tefillin is tightened, then wrapped around the arm seven times. The knot formation and arm binding differ considerably between different traditions. The sephardic minhag is to wrap the seven times outward, away from the body while the ashkenazi minhag is to wrap towards the body. [76] There is a custom to cover the arm Tefillin with the sleeve, in accordance with the verse "And they will be a sign to you...", i.e. to you and not to others. [77]
  2. Next, the head Tefillin is placed on top of the head, "between the eyes" but not lower than the hairline (or if balding, where one's hairline once was). [78] The knot of the head Tefillin sits at the back of the head, upon the part of the occipital bone that protrudes just above the nape. [79] The two straps of the head Tefillin are brought in front of the shoulders, with their blackened side facing outwards. [80]

Removing the Tefillin

  1. According to Ashkenazim, one should remove one's Tefillin standing, however, the Sephardic minhag is to remove the Tefillin shel yad sitting.[81]
  2. The Ben Ish Chai says to remove tefillin as follows: standing or sitting remove finger, hand, and two windings of forearm. Then stand to take off shel rosh and sit to take off rest of shel yad. [82] In contrast, Rav Rephael Baruch Toledano maintains that one should remove Tefillin in the following manner: remove Tefillin shel yad from hand and a little bit of one's arm and Tefillin shel rosh while standing, then wrap the Tefillin shel rosh and return it to its bag, afterwards sit down to remove the rest of the Tefillin shel yad and return it to its bag. [83]
  3. One should remove one's Tefillin shel rosh before one's Tefillin shel yad.[84]
  4. One should not remove one's Tallit until one removed one's Tefillin.[85]
  5. One should wait until at least the kedusha of uva litzion before removing their Tefillin. [86] Preferably though one should wait until after al ken in aleinu lishabeach. [87] There is Kabbalistic significance in waiting until the mourner's kaddish that takes place after alenu leshabeach to take off one's Tefillin. [88]
  6. Ideally, one should learn a little bit of Torah after prayers while still wearing Tefillin. [89]
  7. On a day when there is Kriyat HaTorah, one should not remove his Tefillin until the Torah is returned to the Aron, however, if one must do so, he should put his Tallit over his head when removing the Tefillin shel rosh in order that one's head be covered during the return of the sefer Torah. [90]
  8. When there is a brit mila, one should keep his Tefillin on until afterwards because the brit mila and Tefillin are both an "ot." The minhag is that the sandak, mohel, and father of the son receiving the berit mila procedure keep their Tefillin on. [91]
  9. One should remove the Tefillin shel rosh with his weaker hand to show his desire to fulfill mitzvot and reluctance to stop. [92]
  10. It is a nice practice to kiss the Tefillin upon removing them. [93]
  11. When putting the Tefillin back one should place the Tefillin shel rosh on the bag's left. [94]
  12. One should be careful not to put one's Tallit or siddur on top of his Tefillin when placing one's religious articles bag in his bag. [95]
  13. One should wrap up his Tefillin personally, and not leave it to another to do, in order to demonstrate love for the mitzvah. [96]

Lefties and Righties

  1. A righty wears his Tefillin shel yad on his left hand.[97]
  2. A lefty who writes and does everything that requires one hand with his stronger left hand, wears his Tefillin shel yad on his right hand.[98]
  3. A lefty who writes with one hand and does everything else with his other hand, some say the hand he writes with is considered primary and he should wear Tefillin on the opposite one, while others say that the generally stronger hand is the primary one.[99]
  4. Someone who is ambidextrous should wear his Tefillin shel yad on his left hand. [100]

Wrappings around the Hand

  1. The Tefillin Shel Yad should be put on the left arm on the area where the muscle bulges in the lower half of the area between the elbow and armpit. [101] One should make sure not to put the Tefillin within two fingerbreadths of one’s elbow. [102]
  2. The Tefillin should be tilted slightly towards the body so that when the arm is bent the Tefillin faces the heart. [103]
  3. The knot which looks like a Yud on the Tefillin Shel Yad should be facing inward and touching the main Tefillin box. [104]
  4. The Minhag is to put the Maavarta (bridge) part of the Tefillin facing the shoulder. [105] The Maavarta should also be below halfway between the elbow and armpit. [106]
  5. It’s better that the Maavarta is placed above halfway between the elbow and armpit and not have the main box of Tefillin be within 2 fingerbreadths of one’s elbow. [107]
  6. Many authorities are lenient not to require a Netilat Yadayim if one touches the skin in the area where the Tefillin Shel Yad is placed or rub one’s hair while putting on Tefillin shel rosh, [108] however, some are strict. [109]
  7. Nothing can interpose between the Tefillin or the area where the straps wrap around the arm and one’s body, however, in the area of the knot one may have an interposition. [110]

Physical Separation/Chatzitza

  1. One should ensure that there is no interposition between the Tefillin shel rosh and one's head or the Tefillin shel yad and one's arm. [111]
  2. The following are considered items that separate between the Tefillin and one's body: loose dirt [112], water in your hair [113], a wig [114] a toupee [115], and long hair.[116].
  3. Though it is not befitting for Bnei Torah to have long hair, it does not constitute a Chatzitzah for the Tefillin shel rosh [117]
  4. A wristwatch does not need to be removed. [118]
  5. If one is unable to remove a bandage or a cast he should wear the Tefillin without a bracha. This only applies if the separation is between the body and the boxes, but if the separation is only with the straps the bracha should be recited as usual. [119]

  24. Mishna Brurah 25:1, Halacha Brurah 25:7, Ben Ish Chai Vayera Halacha 3
  25. Shulchan Aruch 25:1 writes that one must not place the Tefillin above the Tallit in fear of taking the Tefillin out before the Tallit. However, Halacha Brurah 25 writes that it is not respectful to the Tefillin to place the Tallit above the Tefillin, therefore it should be placed in a separate bag or to the side of the Tefillin.
  26. Mishna Brurah 25:3 writes that the law that one may not pass up a mitzvah only applies when one intends to do the mitzvah.
  27. This follows clearly from the above Mishna Brurah but is written as an example in Halachot of Tefillin by Rabbi Shlomo Churba (page 7) quoting Or Letzion (vol 2, 44:16).
  28. Kaf HaChaim 25:8 writes that since one does not intend to use the Tallit of Shabbat now one is permitted to take the Tallit of the weekday even if it is underneath.
  29. Rama 25:1 writes that if one has Tefillin but not a Tallit one should not wait for the Tallit but rather just put on the Tefillin. The Magen Avraham 25:2 understands that this is the case even if there is no concern that one will miss Sof Zman Kriyat Shema. Mishna Brurah 25:7 agrees. However, the Machaneh Chaim (Mehudra Kama 2), Sh”t Shenot Chaim 36, Kaf HaChaim 25:10, Yalkut Yosef (Sherit Yosef 1 pg 319), and Halacha Brurah 25:10 argue that one should wait to put on the Tallit as long as one will not miss the time for Kriyat Shema.
  30. Mishna Brurah (Beiur Halacha s.v. Vayitztarech) writes that the principle of putting on the Tallit before Tefillin is relevant also in a case where one took off the Tallit and Tefillin momentarily and now comes to put them back on. This is quoted in Yalkut Yosef (Sherit Yosef 1 pg 318), Halacha Brurah (Birur Halacha 25:2), Amudei HaShulchan 10:2, and Divrei Shalom (vol 1 pg 15).
  31. Ben Ish Chai (Vayera 4, Sh”t Rav Poalim 1:4) writes that if someone is only wearing Tefillin and a Tallit becomes available, one should remove one’s Tefillin before putting on the Tallit. This is also the opinion of the Sh”t Torah Lishmah 1. However, the Rama 25:1 writes that if one has only Tefillin one should put them on and when one gets a Tallit one should don the Tallit implying that one does not need to remove the Tefillin in order to put on the Tallit. Yalkut Yosef (Sherit Yosef 1 pg 319) agrees.
  32. The S”A 25:1 writes that one should be careful not to put the Tefillin above the Tallit in one bag because then one may take the Tefillin first and have to put them on before the Tallit. The S”A here holds that since one picked up the Tefillin the principle of not passing up a mitzvah overrides putting the Tallit on before the Tefillin. Most achronim rule in accordance with S”A including Mishna Brurah and Halacha Brurah 25:9. However, the Kaf HaChaim 25:10 writes in name of the Arizal that one should always put on the Tallit first even in such a case. Therefore, the Sh”t Or Letzion 2:44:16 writes that one should leave the Tefillin and engage in another activity, so that when one returns to the Tefillin one may put on the Tallit first according to all opinions. [This advise of engaging in another activity in order to remove the issue of not passing up a mitzvah is sourced in the Magen Avraham 25:4 and Mishna Brurah 25:3.] Even though the Halacha Brurah 25:9 argues that once one is involved in a mitzvah one is not allowed to engage in a non-mitzvah, still the Divrei Shalom (vol 1 pg 23), Yalkut Yosef (Sherit Yosef 1 pg 315-7), Rabbi Eli Mansour on dailyhalacha.com, and Halachot of Tefillin (by Rabbi Shlomo Churba pg 8) rule in accordance with the Or Letzion.
  33. Magen Avraham 25:1 argues that the principle of not passing up a mitzvah does not apply if one picks up the Tefillin in their bag before taking the Tallit. This is also the opinion of the S”A HaRav 25:3. However, Kitzur S”A 10:2, Maamer Mordechai 25:3, Nehar Shalom 25:1, Nishmat Adam 13:2, Levush 25, Taz 25:10, Eliyah Rabba 25:4, Chaye Adam 13:1, Shalmei Tzibbur (pg 37a), Siddur Bet Ovad (Makom Hanachat Tefillin 1), Kaf HaChaim 25:6, and Mishna Brurah (Beiur Halacha 25:1 s.v. Shelo Yanichu) rule that the principle of not passing up a mitzvah applies even if the Tefillin are still in their bag and therefore one may not simply put tem down again and don one's Tallit but rather engage oneself doing something else, then return and put them on in the right order; Tallit first then Tefillin.
  34. Mishna Brurah 25:4 writes that the principle of not passing up on a mitzvah applies even to when one mitzvah is in the room that one is in and the other mitzvah is in another room. Therefore the same halacha as when one picks up Tefillin before the Tallit applies.
  35. Mishna Brurah 25:5, Halacha Brurah (Birur Halach 25:2)
  36. Mishna Brurah (Beiur Halacha 25) writes that if one is embarrassed to put on the Tefillin first there is a doubt whether one may put on the Tallit first. Yalkut Yosef (Sherit Yosef 1 pg 318) writes that since we hold that the principle of not passing up a mitzvah is only derabbanan, we override the Derabbanan with Kavod HaBriot. Whether not passing up a mitzvah is derabbanan or deoraitah is a dispute in the rishonim and achronim, see Yalkut Yosef (Sherit Yosef 1 pg 317-8).

  41. Rashi Yoma 33b "Avurei" learns this from the concept of ein maavirin al hamitzvot. Tosfot there "avurei" questions this because the gemara Menachot 36a derives this from the pasuk (Devarim 6:8, see above) of Tefillin, which mentions arm before head. Therefore Tosfot interpet the gemara in Yoma as referring to the placement of the Tefillin in the bag. Kitzur Shulchan Aruch of Rav Rephael Baruch Toledano, siman 10, laws of the donning of tefillin, seif 18. Ben Ish Chai Vayera Halacha 6 says that this order has great kabbalistic significance as well. Chazon Ovadia Chelek 2 page 209 says that the order relates to the idea of naase vinishma (Shemot 24:7, that the Jews accepted to observe the commandments and only afterwards understand them) because the Tefillin shel yad represent our actions and the shel rosh represent our understanding

  43. Shulchan Aruch 27:1, 27:6 based on gemara Menachot 37a. Halacha Brurah 27:21 writes that someone who writes with one hand and performs all other activities with another is considered praiseworthy if he places Tefillin on the other hand in addition, however without making a bracha on the second Tefillin. This is also the ruling of Rabbi Eli Mansour http://www.dailyhalacha.com/displayRead.asp?readID=1101

  50. Chida in Machazik Bracha 22, Kaf Hachaim Palachi 10:8 based on Tosfot Menachot 75, against the tosefta Brachot 6:10 which says that when one makes Tzitzit or Tefillin, to make a shehecheyanu, this is brought down by the Rambam Hilchot Brachot 11:9. However, the Beiur Halacha 22:1 and Kaf Hachayim 22:2 both suggest to put on a new garment and say the shehecheyanu on that immediately before putting on Tefillin for the first time, while having in mind to cover the Tefillin as well, in order to avoid the safek.

  111. Bet Yosef 27:4 quotes a dispute between the rosh (Hilchot Tefillin 18, Sh"t HaRosh 3:4) who says that that there may not be any interposition between the Tefillin shel rosh and one's head and the Tefillin shel yad and one's arm and the Rashba (Megillah 24b s.v. Sipah) who allows putting Tefillin on top of an interposition. [See the Sh"t HaRashba Sh"t 3:282 where at first he acknowledges the explanation of the Rosh but comments that this is the halacha lo lemaaseh and continues to elaborate on his own explanation until he concludes that his approach is the halacha.] Shulchan Aruch 27:4 rules like the Rosh. The Rama 27:4 says that this only applies for the batim (boxes) themselves and not the retzuot (straps) but Mishna Brurah 27:16 says that one should not be lenient in this. Shulchan Aruch 27:5 says though that if one needs to lenient for some medical reason and needs a head covering, he can wear them above a thin hat. The Rama there says in that case he cannot say a bracha.
  112. Mishna Brurah 27:14
  113. Shaare Teshuva 27:6 says one should make sure to dry his hair well if he wet it before putting on the Tefillin, both because it could damage the Tefillin, and because the water itself could be considered a separation.
  114. Mishna Brurah 27:16
  115. Iggerot Moshe OC 4:40:18 says that if removing it in public would embarrass the person that he should put on Tefillin in private with a beracha without the toupee and then go to shul and put it on there over the toupee without a beracha but hair that is transplanted is considered part of the head and is not a problem. see Daily Halacha (by Rabbi Mansour).
  116. Machatzit Hashekel 27 and Kitzur Shulchan Aruch 10:6 say that although short hair would not be a problem, excessively long hair could be. The Pri Megadim 27 says that hair which is not located in its place of growth but rather has been brushed across from another part of the head, constitutes a chatzitza in Tefillin. Mishna Brurah 27:14-15 agrees to this, and says that it also could be hard to keep the Tefillin lined up between the eyes and at the right height with long hair. Aruch Hashulchan 27:14 and Rav Ovadia (Yechave Daat 2:2(22)) hold that there is what to rely on regarding really long hair. The Aruch Hashulchan says only hair moved from another place would be problematic.
  117. Yechave Daat 2:2, based on a Sefek Sefeika: maybe the Halacha is like the Rosh (against Maran) that there is no Chatzitzah issue by Tefillin shel rosh, and, even if the Halacha is like the Rashba and not the Rosh, maybe hair is not a Chatzitzah, as it's Min beMino. Additionally, we do not find that the Poskim mentioned a Chatzitza issue for an Avel during Shloshim.
  118. Sh"t Yechave Daat 3:2, Sh"t Yabia Omer 2:2 and Rav Ovadia writes that one who is stringent will be blessed. Emes liYaakov OC 27:note 31 says even though the Rama 27:4 based on the Teshuva of the Rashba 1:827 says one does not need to worry about barriers except for between the skin and the boxes, that if one is accustomed to removing it he should continue doing so, as there are some poskim who are stringent on barriers on any part of the arm or head Tefillin
  119. Sh"t Yabia Omer OC 2:2
