Q: What are the genes that cause male pattern baldness? A: At this time the genes that actually cause hair loss are still unknown. However, there are two gene loci, recently identified, that appear to be associated with common baldness. The first is on the Androgen Receptor (AR) gene carried on the x-chromosome and the [...]

Research Groups Explore Genetics Of Balding
October 15th, 2008We 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.

May 12th, 2008Q: I am 25 year old who just started going bald. My doctor confirmed it’s pattern baldness and put me on Propecia and Rogaine. I don’t want to go bald at any age. So, instead of prolonging the process for 5-10 years and then having a HT, isn’t it easier to let the hair loss [...]

Why Different Hair Loss Evaluation Fees for Diffuse Thinning Versus Patterned Hair Loss?
January 21st, 2008Q: Why is the consult fee more for diffuse thinning than for a regular visit? A: Diffuse hair loss, more common in women, can be the result of a number of underlying medical conditions and therefore it usually requires an extended medical evaluation. If you are a male or female with obvious diffuse thinning from [...]
