Q: I am a 34 year old male and my dermatologist prescribed Propecia for me today. Most of my hair loss is at the hairline, but there is some loss on top as well. It’s not bad, I just want to stay ahead of it. If I get a transplant I want to get it at your clinic, but I will give the Propecia a try first. I am going to be overseas for a couple of months starting this Sunday and I was wondering about the necessity or desirability of having someone measure my hair density prior to starting the Propecia. Would you advise waiting to start the Propecia until I come back in two months and having my density examined at your clinic? — M.R., Great Falls, Virginia

A: I would start Propecia as soon as possible. What is important for a hair transplant is the density in the donor area and this is not affected by Propecia (or minoxidil). Your donor density can be measured anytime at an evaluation prior to surgery. If you want to wait to see the effects of Propecia prior to the hair transplant, you really should wait a year; since growth, if any, can take this long. If you just want to have Propecia on board for the hair restoration procedure, or to make sure you don’t have side effects, then generally a month will do. If you would like to do a photo consult through our website to get some preliminary information about how many grafts you might need, you can do that at your leisure, but start Propecia now since the longer you wait the less effective it will be at regrowing hair.

Q: Didn’t you do free consults in the past? — N.F., Bronxville, NY

A: Yes. It had been in response to the policy of the larger chains. Patients coming to our practice are evaluated by a board certified dermatologist, trained in diagnosing the causes of your hair loss with expertise in both medical and surgical management. Our consults are not just screens for surgery.

Q: I am female and thinning can I be a candidate for a Follicular Unit Hair Transplant?

A: If it turns out that you have female pattern hair loss, you may be a candidate a hair transplant, but would need to be evaluated by a doctor who specializes in surgical hair restoration.

In the evaluation, you should have your degree of hair loss assessed and donor supply measured, using an instrument called a densitometer, to be certain that you have enough permanent donor hair to meet your desired goals. For more information about hair loss in women, please see the Diagnosis of Hair Loss in Women page of the Bernstein Medical – Center for Hair Restoration website.

Q: Do you use computer type imaging to create the best way to ensure you (or any hair transplant surgeon) have the same goal or target “picture” of the particular patient’s restoration as that particular patient has as his “picture?” –F.D., Laude, Missouri

A: I prefer not to do imaging since it tends to oversell the hair restoration procedure.

In addition, the technology is unable to accurately represent what the hair transplant will really look like as there are many hair characteristics that it can’t take into account.

Seeing lots of actual photos of hair transplant patients is much more instructive – and more honest (if the photos are taken correctly). At the time of the consult I design the hairline and photograph it.

Q: I have read that in the evaluation of a patient for hair restoration surgery some doctors use a densitometer to measure miniaturization – the decrease in size of hair diameters. I read that miniaturization is a sign of genetic hair loss, but when there is miniaturization of greater than 20% in the donor area, a person may not be a good candidate for hair transplants. Is this correct and does 20% miniaturization mean that 20% of the population of terminal hairs have become fine vellus-like hairs or that there is a 20% decrease in the actual diameter of each of the terminal hairs? — B.A., New Albany, Ohio

A: Miniaturization is the decrease in hair shaft length and diameter that results from the action of DHT on healthy, full thickness terminal hairs. The hairs eventually become so small that they resemble the fine, vellus hair normally present in small numbers on the scalp and body. Miniaturized hairs have little cosmetic value. Eventually miniaturized hairs will totally disappear. Twenty percent miniaturization refers to the observation, under densitometry, that 20% of the hairs in an area show some degree of decreased diameter.

In the evaluation of candidates for hair transplantation, we use the 20% as a rough guide to include all hairs that are not full thickness terminal hairs. Of course we are most interested in the presence of intermediate diameter hairs — i.e. those whose diameters are somewhere between terminal and vellus and are clearly the result of DHT. I don’t know if one can tell the difference on densitometry between vellus hairs, fully miniaturized hairs and senile alopecia. The partially miniaturized population is most revealing.

Miniaturization in the recipient scalp (i.e. the balding areas on the front top and crown that we perform hair transplants into) is present in everyone with androgenetic hair loss. Miniaturization in the donor area, however, is less common (in men). It means that the donor area is not stable and will not be permanent. Men with more than 20% of the hair in the donor area showing miniaturization are generally not good candidates for hair transplant surgery.
