====== Male Pattern Hair Loss ======

a.k.a. '//Androgenic alopecia//' '//Androgenetic alopecia//' and '//Alopecia androgenetica//'

A variety of genetic (and possibly environmental) factors probably play a role in causing //Male Pattern Hair Loss// in humans. Many are documented, but there is no overall scientific agreement (although the link with androgen hormone levels is well established).\\

The syndrome affects around 50% of men over the age of 50 years.\\

Chinese, Japanese, and African American people are less affected than Caucasians. The hair loss is due to //miniaturisation of the hair follicles// rather than their elimination.

If there are any Darwinian or psychosocial advantages to those affected by //Male Pattern Hair Loss//, they are as yet unproven.

//Note:// A lower percentage of women are affected by severe hair loss, with the name change to [[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4989388/|Female Pattern Hair Loss ]] (FPHL). The cause(s) are also as yet unclear.
