With the limited number of scalp donor hair available and the growing demand to cover the bald area, the quest for greater donor hair aroused. Thus began the concept of body hair transplant (BHT) in which hair follicles from other parts of the body including beard, chest, arms, axilla, pubic area and legs are used as additional source of grafts for covering the scalp or recosntruct any other body area.
BHT is practically exclusive for men. The characteristics of the body hair differ from the scalp hair with respect to its hair cycle, growth, number of hair and direction of growth.
Inspite of these differences, the body hair when transplanted to the scalp can grow up to 15cms length and can simulate the scalp hair character. Indications of body hair transplant
The harvesting of the grafts in BHT will be done using the follicular unit extraction technique. Know More
Tumescent anaesthesia (a form of local anaesthesia) is preferred for the extraction in BHT which is a safe and efficient way to achieve analgesia.
The extraction time is usually longer than the regular scalp transplant. The angle of follicular unit is mostly acute and the hair grow in variable direction. This makes body hair FUE a difficult and time consuming procedure as the surgeon has to keep changing direction of the punch repeatedly.
The body hair is generally mixed with scalp hair and implanted on the mid-scalp or crown region for better blending.
The logic of BHT is based on the principle of ‘recipient influence’ wherein the hairs transplanted from body ( beard, trunk, axillae, and pubis) to the scalp will eventually take up the characteristics of the scalp hair and will grow and cover the scalp.
The technique of body hair transplant is basically Follicular Unit Extraction (FUE) or one by one. The donor areas extend from just scalp hair to beard, chest, arms, legs etc. BHT is used primarily in cases where the donor area on the head is no longer suitable for the extraction of donor material or is not dense enough. Then we do the evolution of possibility of hair transplant from body. If the physiological requirements are met, follicular units can be extracted directly from different area of the body – chest, abdomen, arms or legs – and transplanted to the scalp. The grafts taken in BHT are known to have different growth cycle but a concrete study is yet to prove. Also these are different from scalp grafts as these contain only 1 hair compared to 1 to 4 hairs in scalp grafts.
There are minimal side effects of body hair transplant. However the most commonly encountered side effects include:
Donor area: The antibiotic covering shall be given for a period of 1 week, donor area dressing is done with antibiotic cream. No bandaging is required and donor area heals within 7 days.
Recipient area: Same as post-operative care in FUE. Oral and topical medications for maintaining the transplanted and pre-existing hair shall be administered. More on Post-Op Care After Hair Transplant
