Pathogenesis and Classification of Male Pattern Hair Loss (Androgenic Alopecia)

Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

DHT is not the only cause of male pattern hair loss; genetic sensitivity, inflammation, and fibrosis also contribute. GHK-Cu, a copper peptide, is being explored as an alternative treatment to finasteride and minoxidil, showing potential in improving follicle health.

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

Androgenetic alopecia is affected by scalp DHT levels, not sensitivity, with treatments like finasteride and dutasteride aiming to optimize these levels. Personalized DHT management is crucial for effective hair growth.

DHT is essential for androgenetic alopecia, not testosterone. Treatments like finasteride and dutasteride reduce DHT, halting hair loss.
