Polymorphic CAG repeat numbers in the androgen receptor gene of female pattern hair loss patients
July 2011
in “Journal of Dermatology”
TLDR Longer CAG repeats in gene linked to more severe hair loss in females.
This document summarizes two studies on female pattern hair loss (FPHL) patients. The first study found no correlation between the CAG repeat numbers in the androgen receptor (AR) gene and the therapeutic efficacy of finasteride in 37 Japanese FPHL patients. The second study found a correlation between the length of the CAG repeat polymorphism in the AR gene and the severity of hair loss in FPHL patients. The longer the CAG repeat, the more severe the hair loss.

Cited in this study
research Gene-wide association study between the aromatase gene (CYP19A1) and female pattern hair loss
Aromatase gene variation may increase female hair loss risk.
research The Hair Follicle as an Estrogen Target and Source
Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.
research Current and novel methods for assessing efficacy of hair growth promoters in pattern hair loss
New methods improve how we test hair growth treatments, but challenges like slow hair changes and high costs remain.
research Female pattern hair loss
FPHL is a common, age-related, genetic hair loss with unclear causes and limited treatment options.

Finasteride increases hair weight and count in men with hair loss.
research Managing Cutaneous Manifestations of Hyperandrogenic Disorders
Birth control pills help treat skin and hair growth problems linked to high male hormone levels.
research Finasteride in the treatment of men with androgenetic alopecia
Finasteride safely and effectively treats male pattern hair loss, but may cause reversible sexual issues and harm male fetuses.
research Androgen Receptor Polymorphisms (CAG Repeat Lengths) in Androgenetic Alopecia, Hirsutism, and Acne
Shorter CAG repeats may cause hair and skin issues, while longer ones may link to acne.
research Classification of the types of androgenetic alopecia (common baldness) occurring in the female sex
Common baldness, also known as Androgenetic Alopecia, is caused by a combination of genetic factors and hormones called androgens.
