Permeant Lipophilicity and Vehicle Composition Influence Accumulation of Dyes in Hair Follicles of Human Skin

The conversation discusses the lack of public information on the chemical structure of PP405, a hair loss treatment, and the challenges of synthesizing it without a patent. It also explores a patent related to hydrogen-based topical formulations for reducing oxidative stress and inflammation.

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.

Rotenone, a natural plant extract, may promote hair growth by increasing LDH activity and blocking MPC in the scalp, but it carries risks due to its toxicity. The suggested formulation includes Barbasco extract, DMSO, propylene glycol or PEG-400, ethanol, and a carrier oil.

The conversation is about making and selling RU58841 scalp lotion by mixing the powder with ethanol and propylene glycol. The user is considering selling it as a lotion due to import restrictions in their country.

A user is attempting to reformulate a topical gel using PP-405 for hair loss, aiming to enhance its effectiveness with additional compounds. They discuss the potential of PP-405 compared to other treatments like Minoxidil and GT20029, and emphasize the importance of proper formulation for efficacy.

Minoxidil can be effectively delivered through nanoemulsions containing eucalyptol or oleic acid, enhancing its diffusivity and targeting hair follicles. This contradicts the advice against mixing minoxidil with oils in topical formulations.
