Male Pattern Androgenetic Alopecia

This study suggests that miniaturization in pattern hair loss may occur abruptly and can be reversed with treatment, as supported by histologic evidence in finasteride-responsive patients.

In this study, the prevalence of androgenetic alopecia among Korean men and women was found to be lower than in caucasians, with Korean men showing more frontal hairline preservation and a higher incidence of 'female pattern' hair thinning.

Different factors help diagnose and treat hair loss accurately.

This study found that oral finasteride 1 mg/day promotes hair growth and prevents further hair loss in a significant proportion of men with male pattern hair loss over two years.

Genetics and hormones cause hair loss; finasteride treats it safely.

This study found no significant genetic association between the 5α-reductase enzyme genes and male pattern baldness, suggesting a polygenic etiology rather than simple inheritance.

This study demonstrates that patients with benign prostatic hyperplasia have a higher severity and frequency of male pattern baldness compared to a control group.

Too much androgen can cause hair loss; finasteride may help.

This study found that frontal and frontoparietal hair recession is relatively common in women, especially after menopause, and may not indicate abnormal androgen metabolism absent other virilization signs.

This study presents evidence suggesting that androgenetic alopecia is most likely inherited through a polygenic model, challenging the traditional view that it is caused by a simple Mendelian autosomal dominant gene.

This study found that individuals with androgenic alopecia have an increased number of thin hairs (less than 40 microns in diameter) per cm², which may affect their clinical appearance.
