female pattern hair loss FPHL AR/EDA2R 20p11 genetic susceptibility loci early-onset FPHL male pattern baldness susceptibility alleles

TLDR AR/EDA2R gene linked to early-onset female hair loss, but 20p11 gene not involved.

This study investigated the role of two major genetic susceptibility loci, AR/EDA2R and 20p11, in female pattern hair loss (FPHL). The study involved 145 UK and 85 German patients with FPHL, 179 UK supercontrols, and 150 German blood donors. The results showed that the AR/EDA2R locus confers susceptibility to early-onset FPHL, but the 20p11 locus is not implicated in the aetiology of FPHL. The study suggests that FPHL and male pattern baldness share common susceptibility alleles.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 3 months ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

A user's experience with hair loss treatments such as finasteride, ketoconazole, and oral minoxidil that have not yielded any results; other users suggest shaving the head or getting a wig, while others offer additional advice such as seeing a dermatologist, checking thyroid levels, switching to dutasteride and adding needling, and trying stemoxydine.
