androgenetic alopecia male pattern hair loss endocrine factors genetic predisposition Norwood-Hamilton classification topical minoxidil hair restoration surgery AGA Rogaine

TLDR Male pattern hair loss is genetic and influenced by hormones, with treatments like minoxidil and surgery available.

This document from 15 years ago discusses androgenetic alopecia (AGA), or male pattern hair loss, which is the most common form of alopecia in men and can be seen as a genetically determined event. The development and occurrence of AGA depends on an interaction of endocrine factors and genetic predisposition. The document also discusses the clinical features and classification of AGA, as well as its prevalence and ethnic differences. The Norwood-Hamilton classification is used for the assessment of efficacy of drugs for hair restoration in clinical trials. The document also covers various treatments for AGA, including topical minoxidil and hair restoration surgery.
