Q: If I stop the treatment will any benefit that I had be lost?

A: As with other medical therapies for hair loss, once the treatment is completely stopped, any benefit should subside.

It is anticipated, therefore, that periodic treatments will be needed after than the initial treatment course.

 

Q: How long will Low Level Laser Therapy (LLLT) treatments for hair loss last?

A: The studies submitted to the FDA looked at the effects of low level lasers over a 6-month period. There is no published data for use beyond this time period.

Therefore, the long-term effectiveness of these lasers in treating hair loss is not currently known.

 

Q: I have had thinning eyebrows since my early twenties (I am now 32) and they have gotten to the point that I can’t make them look good with mascara anymore. I am considering an eyebrow hair transplant, how is it different from other hair transplants?

A: Eyebrow hair restoration procedures are similar to hair transplants to the scalp in that the hair, once transplanted, is permanent. They differ both in the techniques used to perform them and in the results.

In eyebrow transplants, only individual hairs should be used, whereas follicular units containing from 1 to 4 hairs are used in a hair transplant to the scalp. In eyebrow transplants, the hairs must be positioned to lie as flat as possible to the surface of the skin. In hair transplantation to the scalp, the angle between the hair and the scalp surface can be as much as 45 degrees or more.

As with hair transplants to the scalp, the hair transplanted to eyebrows will continue to grow and must therefore be cut. However, in contrast to hair transplants where the donor hair is generally a perfect match for scalp hair, in eyebrow transplants the hair is taken from a different part of the body and will have slightly different characteristics both in growth rate and in appearance.

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?

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.

 

Q: I had my second hair restoration procedure nearly 5 months back. New hair in the front part of the head is growing well, but the crown is growing slow. Is this common? Also does the new hair grow more slowly after second hair transplant procedure?

A: Yes, it is typical for hair in the crown to grow more slowly than the front and top of the scalp and the second procedure generally grows more slowly than the first.
