HairDX LLC, pioneers of consumer-friendly genetic tests for hair loss, has introduced the first meaningful test using genetic markers strongly associated with Female Hair Loss, Female Androgenetic Alopecia (AGA). The HairDX test for Female Hair Loss provides women with a score, called the CAG repeat score. The smaller the score the higher is the risk for significant hair loss (Ludwig grade II or III hair loss) and vice versa. Female AGA loss has been difficult to diagnose because women don’t develop a pattern like men do.
