Switching from propylene glycol to glycerin in topical finasteride may reduce systemic absorption and side effects while maintaining local scalp DHT suppression. Concerns exist about glycerin's ability to deliver the full dose to hair follicles.
Homemade topical finasteride solutions are discussed, with one user using 30% ethanol, 50% propylene glycol, and 20% water. Alternatives like dissolving finasteride pills in minoxidil and using stemoxydine are also mentioned.
A user is considering using 70% isopropyl alcohol with glycerin as a carrier for topical finasteride for hair loss but is concerned about its safety compared to ethanol. They are unsure where to buy ethanol without toxic methanol.
The conversation is about making a solution of RU58841 using propanediol instead of propylene glycol due to skin irritation. The user seeks advice on whether this substitution is acceptable.
The conversation is about the best vehicle for RU58841, comparing trichosol and Garnier/Vichy Stemoxydine, avoiding propylene glycol (PG) or ethanol due to previous scalp damage. The user is also seeking sources for these products in the EU.
The conversation is about the effectiveness of Minoxidil formulations with different alcohol and propylene glycol (pg) ratios. The user finds that a formulation with 20% pg and 80% ethanol dries faster but is concerned about absorption time.
The conversation discusses adjusting the isopropyl alcohol, propylene glycol, and water ratios in a topical finasteride solution for better scalp comfort and less dandruff. The user considers using 20ml IPA, 25ml PG, and 15ml water in a 60ml bottle, moving away from mixing finasteride with topical minoxidil.
The conversation discusses using propanediol as an alternative to glycerin in PG-free minoxidil for better absorption. The user also plans to try nanoxidil, which may absorb more easily due to its smaller molecule size.
Koshine KX-826 has different versions, and the green version uses a plant-based carrier that may be less irritating for those sensitive to propylene glycol. Users report irritation with some versions of KX-826.
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.
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 the stability of pyrilutamide in different solutions. The user is asking if a 70/30 ethanol/pg solution with 4% water will degrade pyrilutamide.
Isopropyl alcohol should not replace ethanol in homemade topical finasteride serums due to potential toxicity with frequent use. Denatured ethanol, also known as parfum or cosmetic alcohol, is a safer alternative.
A user is seeking advice on creating a homemade finasteride foam similar to over-the-counter Minoxidil foam, due to issues with glycerin and propylene glycol in their current solutions. They are considering using a mixture of ethanol/alcohol and water for the foam.
The conversation is about creating a DIY topical finasteride solution using ethyl alcohol and propylene glycol. A user suggests using a compounding pharmacy instead.
Doctors are testing verteporfin topically for healing and potential regeneration after transplants. The user is asking how it is formulated for topical use, such as if it's mixed with a carrier gel.
The conversation discusses the differences between PG/Ethanol and KB solutions for RU58841 application, focusing on potential scalp irritation. KB solution is suggested for those allergic to PG, though both contain ethanol which can dry the scalp.
A user is seeking UK-based sources for propylene glycol and ethanol to dilute topical finasteride for hair loss treatment. They currently order from MinoxidilMax but want a faster shipping option.
The user is using Dutasteride and oral Minoxidil for hair regrowth and is considering adding topical Minoxidil but is allergic to propylene glycol, which is present in the product they found. They need a solution with tretinoin that does not contain propylene glycol.
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.
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.
Oral minoxidil was ineffective for OP, causing hair loss and unwanted body hair, while topical minoxidil showed significant regrowth. OP is switching to topical minoxidil with glycerin due to scalp issues with propylene glycol.
A user made a 70/30 ethanol/propylene glycol topical finasteride solution but noticed chunks at the bottom. The discussion focuses on this issue with the DIY hair loss treatment.
A user applied the 8T3 product for hair loss, targeting LPP and AGA, and plans to update on its effectiveness. The product uses a saline buffered phosphate vehicle, suitable for those intolerant to ethanolic vehicles.
The user is considering making a homemade topical finasteride solution using an ethanol-based carrier. They are inquiring if a solution containing partially denatured ethyl alcohol and benzalkonium chloride is suitable.
The conversation is about making a 20mg/ml RU58841 solution for hair loss treatment using ethanol and propylene glycol. The user receives advice on calculating the correct amount of RU58841 powder needed.
OP asked if a product from Amazon is sufficient to dilute finasteride. A user advised against using propylene glycol alone, suggesting a pre-made solution instead.
Kintor plans to release pyrilutamide foam and a plant-based Koshine by year-end, with GT20029 progressing in their pipeline. Users are pleased about the absence of propylene glycol (PG) in the new products.
