Ultrastructural Aspect of the Keratinolytic Activity of Piedra

The conversation discusses hair regrowth after a health condition, with the appearance of white substance on the scalp. Suggestions include it being sebum or White Piedra, with a recommendation to try Nizoral.

Hair loss may be linked to the TRPS1 gene and protein, not just DHT. Amplifica's AMP-303 targets mesenchymal stem cells and shows promise in treating hair loss, unlike Pelage's PP405.

Hair loss without a white bulb may indicate mechanical damage, anagen effluvium, alopecia areata, or traction alopecia. Seeking a specialist is recommended, but access can be difficult in smaller areas.

Switching from ketoconazole to a ciclopirox and zinc pyrithione shampoo significantly reduced hair fall. The user is considering whether to continue using ketoconazole occasionally or combine both shampoos weekly.

Pelage is developing a topical hair follicle stem cell therapy, PP405, for non-scarring alopecias like androgenetic alopecia, with Phase III trials planned and a potential market launch by 2027. The treatment may not require continuous use after initial regrowth.

Zinc pyrithione and piroctone olamine are effective for reducing hair shedding, possibly more so than ketoconazole. There is a concern about zinc pyrithione shampoo interfering with minoxidil, but it's unclear if this is proven.
