The Hair Follicle and Hair Loss: A Review of DHT, Inflammation, Oxidative Stress, Vascular Signaling and the Biological Pathways Behind Hair Growth

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.

Reducing scalp DHT doesn't directly correlate with preventing hair miniaturization, as different follicles have varying sensitivity levels. Dutasteride at 0.5 mg and 2.5 mg shows minimal visual difference in hair regrowth, with side effects being a consideration for higher doses.

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

The conversation discusses whether finasteride's reduction of DHT and increase in scalp testosterone contribute to hair follicle miniaturization. Some participants argue testosterone does not cause miniaturization, while others suggest that even with reduced DHT, other androgens like testosterone may still contribute to hair loss.

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.

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.
