Do You Perform Hair Transplants With Body Or Leg Hair?

Q: Dr. Bernstein, can you please comment on leg and body hair transplants? — J.R., Ridgewood, NJ

A: I’ve tried the technique in the past but have been dissatisfied with the results. Scalp hair, unlike the rest of the body, has multiple hairs rising out of each follicle. With leg and body hair, you have only one hair per follicle, not follicular units of multiple hairs. Leg hair is also very fine. It might thicken up a little bit after it is transplanted, but not enough to be clinically useful. In men you want full thickness hair, so fine hair can make it look like it is miniaturizing, as it does when you’re losing it.

Can Body Hair Transplant be Negatively Affected by Finasteride?

After trading anecdotes with fellow hair loss physicians about how finasteride can reduce body hair in some patients, Dr. Sharon A. Keene asked whether finasteride might have a negative effect on patients who have body hair transplant (BHT) procedures. While the current research is inconclusive, her review sheds light on how to avoid any possible negative impact that finasteride might have on patients who have body hair transplant procedures.

Could Finasteride (Propecia) Remove Unwanted Body Hair?

Q: I’m concerned that finasteride might result in unwanted body hair on the arms, back, etc. Is there any truth to this? My thinking is that since finasteride blocks the enzyme 5 alpha-reductase which converts testosterone to its more active form, DHT (dihydrotestosterone), is it possible that it might actually have some effectiveness in ameliorating unwanted hair? — P.P., Stamford, CT

A: Yes, finasteride does have some ability to decrease body hair, since growth of body hair is stimulated by DHT. However, the effects of finasteride are mild and not observed by everyone, so if you have unwanted body hair you will probably need some other means to remove it such as waxing, laser hair removal or electrolysis. The important thing is that finasteride doesn’t increase body hair.

Will Propecia Cause Or Inhibit Chest Hair Growth?

Q: I am currently 28. I have been taking Propecia for 6 years and recently began to grow sparse chest hair for the first time in my life. Is the Propecia causing these effects? — H.L., Gowanus, Brooklyn, NY

A: DHT causes male pattern baldness and stimulates the growth of body hair. The use of Finasteride, a DHT blocker, will permit scalp hair to grown and inhibit the growth of body hair, not stimulate it.

However, the effects on body hair are quite small, so your natural tendency to grow chest hair over time is probably not being blocked by the treatment.

Can Hair Loss be Caused by Thyroid Problems or Fluctuations in Hormones?

Q: One of the things that I have noticed as a person who has needed to take thyroid medication for a long, long time, is that when my thyroid gets a little bit out of balance – when I’m not getting quite enough, I begin to notice is that my hair starts falling out. What about the role of thyroid for hair loss? — T.K., Mineola, NY

A: Both increases and decreases in thyroid levels can cause hair loss and changes in the levels of thyroid hormone can change the consistency of one’s hair. Elevated hormone levels cause scalp hair to be fine and soft, with diffuse thinning being relatively characteristic.

When thyroid hormone levels are low, the hair becomes dry, coarse, and brittle. Hair loss can be either patchy or diffuse (involving the entire scalp).
