    TLDR Genetic variants at 20p11 increase baldness risk in Chinese Han people.
    This study found that genetic variants at 20p11 confer a risk to androgenetic alopecia (AGA) in the Chinese Han population. The study analyzed five single nucleotide polymorphisms (SNPs) in 445 cases and 546 controls and found that the rs2180439 SNP was significantly associated with AGA. The study suggests that the HDAC9 gene may be a new candidate gene for male-pattern baldness. The study also found that the PAX1 gene may confer the AGA-relevant effect at this locus and that a regulatory variant within the associated LD block may modulate its expression through long-range control.

      community Oral Minoxidil - The Hyper-Responder Concept

      in Research/Science  6 upvotes 6 days ago
      Minoxidil's effectiveness varies due to genetic differences in the SULT1A1 enzyme, affecting how well it converts to its active form, minoxidil sulfate. Hyper-responders may experience rapid hair growth and increased side effects, such as pericardial effusion, even at low doses.

      in Finasteride/Dutasteride  101 upvotes 1 year ago
      Dutasteride significantly reduces scalp DHT levels and can save hair, though shedding is part of the process. Some users report success with dutasteride, while others struggle despite using it along with finasteride and oral minoxidil.

      community Why does it seem everyone favors finasteride over dutasteride?

      in Female  62 upvotes 1 year ago
      The conversation discusses preferences for hair loss treatments, specifically finasteride over dutasteride. Users share personal experiences, cost considerations, FDA approval status, and potential side effects, with some switching between treatments to find what works best for them.

      community Why do we get bald from evolutionary perspective

      in Chat  213 upvotes 4 months ago
      Baldness is not an evolutionary disadvantage because it occurs after reproductive age. Treatments like Minoxidil and Finasteride are used for androgenetic alopecia but don't address the root cause.
