Q: I am 24 years old and just starting to thin. I was told by another doctor that it was too early to have a hair transplant, but the hair on the back and sides of my scalp seems really thick. Shouldn’t I have a hair transplant now, just in case I am not a candidate in the future?

A: The most important criteria in determining who will be a candidate for a hair transplant is the presence of sufficient permanent donor hair. When hair loss is early, it is often hard for the doctor to determine this, since early on the donor area can appear very stable. It is not until the front and/or top of the scalp has significant thinning that the donor area may also show thinning. Therefore, it is only at this time that the stability of the donor area can adequately be assessed.

We all have seen that some bald sons have bald fathers, even when no one on the mother’s side of the family has any hair loss. This suggests that the genetics of male pattern alopecia is more complicated, with multiple genes influencing hair growth. And it is likely that the inheritance of baldness is polygenetic, with relevant genes coming from both the x-chromosome of the mother and non-sex chromosomes of either parent. So where are the other genes?

Two independent research groups, one from England and the other Germany, both published in the journal Nature Genetics, have identified a gene locus p11 on chromosome 20 that seems to be correlated with male pattern hair loss, and since the gene is on a non-sex chromosome, it offers an explanation for why the inheritance of common baldness can be from either side of the family.
