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.
Scalp tension from the occipitalis muscle is theorized to contribute to hair loss, but most believe DHT and genetics are the main causes. Treatments like finasteride and minoxidil are considered more effective than addressing scalp tension.
The conversation is about using finasteride and testosterone replacement therapy (TRT) for hair loss and their role in gender-affirming care. It debates whether these treatments are considered hormone replacement therapy (HRT) and their implications for both cisgender and transgender individuals.
PP405 is a promising new hair loss treatment that may reactivate dormant hair follicles without side effects. It could surpass traditional treatments like minoxidil and finasteride if successful in further trials.
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.
