Essentially it is FUE (Follicular Unit Extraction) but often; acute exit angle; bulky soft tissue underneath without strong bony support of Body hairs makes it more difficult than that from the scalp. Usual sites are Beard, Pubic, Chest and Back.
Precaution:
For avoiding the telogen hair from extracting you need to shave the area about 4-5 days in advance of the procedure because the telogen hair are likely to be damaged during extraction due to flimsy the nature of its secondary germ structure.
Body hair varies in caliber, texture and color. It is recommended to mix body hairs with scalp hair to achieve a uniform look and feel.
Body hairs from various areas have been used:
Dry zone: Beard, chest, back, limbs, abdomen
Wet zone or Apocrine zone: Armpits and pubic hairs. In the case of sweat produced by the
apocrine glands, which are located near hair follicles on the scalp, underarms, and groin area, the sweat contains fatty compounds.
Bacteria feed on this sweat when it is secreted to the skin’s surface, and the resulting
waste products, fatty acids, ammonia, and chemical reactions form a an odor which is unique for every individual.
