Emulsifying Properties of Alpha-Chitin Nanofibrils Prepared by Aqueous Counter Collision

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.

OP is trying to dissolve finasteride powder for a topical solution but faces issues with it not dissolving properly in ethanol or water. Users suggest methods like using a magnetic stirrer, shaking the mixture, or filtering out fillers, with some noting that finasteride is soluble in alcohol.

The conversation discusses using NAC and quercetin as supplements for hair loss, with some users also mentioning finasteride. NAC is highlighted for its potential benefits, but concerns about its safety and absorption are also raised.

The user is experiencing scalp irritation from using RU58841 with a 70% ethanol and 30% propylene glycol vehicle and is considering switching to a less irritating vehicle, such as 30% ethanol with 70% squalane or emu oil. They are seeking feedback on the effectiveness and irritation levels of these alternative carriers.

The conversation is about using distilled water as a solvent for topical finasteride to reduce systemic absorption. The user is considering avoiding ethanol and propylene glycol to achieve this.

Fibrin-based hydrogels support stem cells for hair follicle regeneration, showing promise for treating alopecia and wound healing. They enhance cell viability, maintain stemness, and promote hair and tissue regeneration without teratoma formation.
