Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.
Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgensignaling and TGF-beta may help prevent hair loss.
Hair loss is linked to scalp fibrosis and tension, which result from chronic mechanical stress and androgenicsignaling. Treatments include blocking androgens with finasteride, promoting hair growth with topical minoxidil, and improving scalp mobility through exercises.
Exploring hair loss treatments beyond DHT, including Minoxidil, pyruvate, Gt20029 targeting androgen receptors, and vasodilators. Other options like Kx826, adenosine signaling, growth factor topicals, and microneedling are also discussed.
The conversation discusses making a topical melatonin solution for hair loss treatment, questioning if isopropyl alcohol can dissolve melatonin. Melatonin is soluble in lipids and alcohol, but it's unstable and should be mixed fresh regularly; it may help hair growth by affecting certain cellular signaling pathways and has anti-androgenic effects.
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.
