Toxicology and Pharmacology of Botulinum and Tetanus Neurotoxins: An Update

Intradermal botulinum toxin (BTX) injections effectively treat androgenetic alopecia (AGA) by inhibiting TGF-β1 secretion from hair follicles. Further research and long-term follow-up are needed to confirm these findings.

The conversation discusses using Botox to treat male pattern baldness, suggesting it may promote hair growth by increasing scalp blood flow and oxygen, reducing dihydrotestosterone levels. The user wonders why this treatment is not widely discussed or if it has been discredited.

Botox in scalp muscles is being discussed as a potential hair loss treatment. Minoxidil, finasteride, and RU58841 are also mentioned as treatments.

Botox injections increase hair density in patients with androgenetic alopecia. Combining Botox with finasteride yields even better results.

The trial for TDM-105795 has been completed, and it was in phase 2A. The discussion seeks input on the next phases, 2B or 3, based on safety and efficacy.

The conversation discusses the delay in the PP405 Phase 2 study results, now expected by the end of 2025, and skepticism about research practices. There is also mention of optimism for Amplifica's AMP303 and a topical treatment in early testing.
