Over the years, I’ve had many different hair styles and not a year goes by without me wondering if it would just be easier to shave it off. But I’m being facetious. Readers of Baldiness and its author, Laura Bzowy, certainly care about hair loss and its effect on all aspects of life. And so, apparently, do the folks at HairDX.
HairDX is a $149 genetic test for male pattern baldness also known as androgenic alopecia. It examines unspecified SNPs in genes on the X chromosome that code for the androgen receptor. A previous study in 2005 showed that the genetic variant which codes for excess androgen receptors lies on the X chromosome and is the major determinant of male pattern baldness. HairDX claims that the high risk genetic variants they study account for 95.1% to 98.1 of cases of early onset baldness before the age of 40.
Why take a genetic test for a condition that is not life threatening? HairDX CEO Andy Goren is trying to help you save money:
Each year, men in their twenties and thirties spend millions of dollars on pharmaceuticals, topical products, and other costly treatments trying to prevent baldness. Some of this is done by males who may not go bald in the first place.
So here’s the breakdown:
Positive HairDX – Sorry, you lose the genetic lottery.
Negative HairDX – Sorry, you could still lose your hair because of other reasons, genetic or otherwise.
In any case, I think this guy’s a lost cause.
It’s Rick Vidal from My Biotech Life! Still looking good minus a few strands of hair.
