5 / 489 resultscommunity Anyone on topical fin using glycerin instead of PG as humectant?
Switching to a DIY topical finasteride solution using ethanol, glycerin, and distilled water instead of propylene glycol for a gentler application. Users report positive results with both DIY solutions and a low PG minoxidil and finasteride product from India.
community Making topical finasteride with ethanol + propylene glycol vs mixing it with topical minoxidil
The conversation discusses two methods for making topical finasteride: using ethanol and propylene glycol or mixing it with topical minoxidil. The focus is on solubility and absorption, with a suggestion to crush pills finely and possibly mix with minoxidil at a slightly elevated temperature.
community Are we underestimating systemic absorption with homemade/generic Topical Fin? (HPCH vs. PG/Ethanol formulations)
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.
community Best way to go about making a DIY topical fin for someone who's allergic to PG?
The conversation discusses creating a DIY topical finasteride solution for someone allergic to propylene glycol, with suggestions to use glycerin or a glycerol-based vehicle instead. The user also mentions using foam minoxidil.
community Best way to go about making a DIY topical fin for someone who's allergic to PG?
A user allergic to propylene glycol seeks alternatives for a DIY topical finasteride solution, considering glycerin or glycerol-based vehicles. Another user suggests a recipe using propanediol, DMSO, MCT oil, and peppermint oil, incorporating minoxidil, dutasteride, and finasteride.
