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.
Dutasteride takes 1-3 months to affect scalp DHT levels, not just a week. The prostate absorbs Dutasteride faster than the scalp due to different vascular networks and enzyme densities.
The user experienced hair loss since 2019 and tried finasteride, dutasteride, RU58841, and ketoconazole shampoo without success. A scalp biopsy showed scarring and inflammation from folliculitis, indicating chronic inflammation was affecting treatment effectiveness.
The conversation discusses whether sunlight exposure affects hair growth or loss, with mixed anecdotes and theories but no clear consensus. Some suggest moderate sunlight can benefit hair by providing vitamin D, while others doubt its effectiveness compared to treatments like Minoxidil or finasteride.
A user with seborrheic dermatitis is experiencing bald spots and hair thinning despite changing their diet and taking oral minoxidil. Another user suggests using ketoconazole shampoo properly, using a scalp massager, applying rosemary/peppermint oil, keeping hair short, and taking fish oil to improve scalp health.
