Q: I had a hair transplant 10 days ago and I lost some hair that looks like the hair fell out at the root. — R.A., Bronxville, N.Y.

A: When there is shedding after a hair transplant, it is the hair that is lost, not the follicle that contains the growth center (the follicle eventually produces the new hair).

Since the “hair” usually consists of a hair shaft and the inner and outer root sheaths, which creates a little bulb at the end of the hair, it looks like the hair is “falling out at the root.” Do not be concerned as this is not the growth center.

The growth center remains in the scalp and is what produces the new hair. If some grafts were to become dislodged and fall out -– which can happen the first few days after the hair transplant — there would be some localized bleeding. At 10 days the grafts cannot be dislodged, even with vigorous scrubbing.

Q: I have heard that Dr. Jahoda was able to clone hair. Is that true? — M.T., Cincinnati, OH

A: Possibly the most interesting work related to cloning hair was done by Colon Jahoda in England over a decade ago. Dr. Jahoda’s work is significant because he identified an inducer cell — i.e. fibroblasts in the outer portion of the hair follicle (the outer root sheath) — that can stimulate the skin to produce new hair. It is well known that fibroblasts, unlike many other tissue cells, are relatively easy to culture.

Theoretically, a patient’s fibroblasts could be removed from the sheaths of just a few follicles and then cultured to produce thousands of follicles. These fibroblasts could then be injected back into the scalp to induce thousands of new hair follicles to grow.

In the study, fibroblasts from a man were injected into the forearm of genetically unrelated women. The cross-gender aspect of his experiment has received much publicity and is potentially of great importance to burn victims, but has little relevance to hair transplantation for male pattern baldness. Patients would probably benefit most from using their own cultured fibroblasts for the best match.

So far this important single study has not been reproduced.
