Micro-Segmental Hair Analysis: Detailed Procedures and Applications in Forensic Toxicology

Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

A peptide-based delivery system for finasteride shows promise in reducing systemic side effects while maintaining hair growth effectiveness. Combining this with other treatments like minoxidil and RU58841 could enhance results with lower systemic absorption.

Hair loss treatments, specifically, discussing the effectiveness and side effects of finasteride, minoxidil, and RU58841 in various microdoses. It also includes an updated graph which provides information on how different doses affect DHT levels, scalp skin and serum androgen levels, as well as hair count.

New hair loss treatments like GT20029, Clascoterone, and PP405 are being discussed, with concerns about how to apply multiple topicals alongside existing treatments like minoxidil and finasteride. Suggestions include creating a routine, mixing treatments, or minimizing redundancy in treatment stacks.

David Barreto shared that a London-based research group is conducting a 12-month trial for a new nutraceutical treatment for pattern hair loss, designed with Dr. Carlos Puig. The trial aims to provide robust data, with results expected in 1-2 years, potentially representing a significant advancement since finasteride’s introduction in 1997.

A user created a tracker for hair loss treatments in clinical development, including compounds like Dermaliq, RU58841, and Pyrilutamide. The tracker updates with new information and allows filtering by conditions like androgenetic alopecia (AGA) and alopecia areata (AA).
