Effect of PEG 400 concentration on the physicochemical characteristics and stability of Persea americana seed oil nanoemulsion hair spray

PP405 shows promise for hair growth with significant results after 4 weeks, but skepticism exists due to its unavailability. Some users are hopeful for its potential, while others express concerns about side effects and market release delays.

Pumpkin seed oil showed a 40% increase in hair count, but its effectiveness is questioned due to other ingredients in the supplement. Users discuss its potential compared to finasteride, with some expressing skepticism and others showing interest.

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.

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.

PP405's effectiveness in increasing hair density is questioned due to a small sample size, despite investment from Google Ventures. Users express skepticism and suggest waiting for more conclusive results.
