This study found that dermal papilla and dermalsheath cells from human scalp tissue differ from interstitial dermalfibroblasts in morphology and produce varying levels of TGF-beta 2.
Hair loss involves more than just DHT, with genetic factors like TRPS affecting hair follicles. Treatments such as Amplifica's AMP-601 and AMP-303 target stem cells for potential hair growth solutions.
Procapil is marketed as a natural hair loss treatment but lacks strong evidence and is industry-biased. Minoxidil and Finasteride are the only FDA-approved treatments for androgenetic alopecia.
Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.
A new treatment using dermalsheath cup cells may regrow hair and could require repeat treatments every 8 years. Users discuss ongoing trials and plan to use finasteride and minoxidil until the treatment is available.
