Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.
Microneedling is effective for hair growth, especially when combined with finasteride and minoxidil, but concerns exist about potential long-term skin damage. Users report increased collagen and elastin deposition, but the long-term effects on the scalp remain uncertain.
Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
Age-linked hair loss is linked to disappearing collagen. Treatments discussed include minoxidil, finasteride, RU58841, tretinoin, microneedling, and collagen supplements.
