Profibrotic Subsets of SPP1+ Macrophages and POSTN+ Fibroblasts Contribute to Fibrotic Scarring in Acne Keloidalis

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.

The user suspects scarring alopecia and is exploring NSAIDs and turmeric/pepper for inflammation-related hair loss, having experienced burning and thinning with finasteride and testosterone reduction. They are seeking feedback while unable to afford a dermatologist.

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.

PP405, a topical treatment, shows promise for hair growth by activating inactive follicles, with 66% of participants experiencing positive results. The treatment is well-tolerated and may proceed directly to Phase 3 trials, offering a potential alternative to minoxidil and finasteride.

The conversation discusses using microneedling with growth factor serum, PRF injections, dutasteride, oral and topical minoxidil, and topical exosomes to treat hair loss, particularly on the crown. OP plans to microneedle twice a month and seeks feedback on Korean growth factor serums.

Hair transplant recipients are concerned about whether dormant follicles are permanently damaged by incisions, but some believe undamaged follicles could still regrow if a treatment like PP405 is effective. Opinions vary on the impact of transplants on original follicles, with some suggesting treatments like finasteride can help regrow hair.
