Body Hair Transplant (BHT) - the preshaving protocol

Body Hair Transplant (BHT) - the preshaving protocol
  • Apr 22, 2019

A larger %age of hair follicles are in resting/ non-growing phase on the body donor areas.

 

It is advisable to use only the actively growing hair for transplant.

 

Preshaving the body donor areas is a simple, non-invasive method to locate the actively growing hair.

 

Please note - The body donor areas should be wet shaved with a razor (trimming with a hair trimmer alone will not suffice), 3 to 5 days before the procedure.

 

If you have very dense and long hair growth, you may first buzz cut the hair with a trimmer, followed by shaving the hair flush with the skin using a razor.

 

The duration of the anagen/telogen phase plays an important part overall, while the %age of hair in telogen gains increasing importance with each passing hair cycle.

 

Talking of durations -

Hair Growth Tables

There are many factors that affect individual hair growth. These growth tables should only be used as a very generalized guide.

 

Telogen (%) Anagen (%) Duration of Activity

 

Scalp 15/ 85/ 2-6 years

Eye Brows 90/ 10/ 4 - 8 weeks

Cheeks 40 - 50/ 50 - 60/

Beard (Chin) 40/ 60/ 1 year

Moustache 45/ 55/ 16 weeks

Arm Pit 70/ 30/ 16 weeks

Pubic Area 70/ 30/ months

Arms 80/ 20/ 13 weeks

Legs & Thighs 80/ 20/ 16 weeks

et al.

 

While the scalp donor hair have a growth phase of, an average, 3 years, most body hair have a growth phase lasting approximately 4 to 5 months.

 

Therefore, unlike scalp to scalp transplants, BHTs will show a marked cyclic variation.

 

Also while 85% of the scalp hair are in growth phase at any particular time, 40 to 80% of the body hair may be in telogen (non growth phase).

 

Thus, the significance of the Preshaving protocol.
