Characterization of the Lipid Composition at the Proximal Root Regions of Human Hair

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.

Topical finasteride in a liposomal formulation reduces systemic absorption compared to ethanol solutions. The user is seeking sources for such products, noting that popular options like morr-f are not liposomal.

A user is interested in creating a hair growth serum using oleic acid, palmitoleic acid, and anhydrous ethanol, and seeks advice on sourcing these ingredients. Another user plans to mix these with minoxidil, which already contains ethanol, and mentions using RU58841.

Ethosomes are suggested as an effective delivery method for topical finasteride solutions, requiring the addition of a phospholipid like soya lecithins. The user questions why do-it-yourself solutions don't commonly use ethosomes despite their potential benefits.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

The user is seeking alternatives to propylene glycol and glycerin for mixing with RU58841 due to allergies and greasiness. Suggestions include reducing glycerin and considering stemoxydine as a solvent.
