Topical Application of Newly Developed Pseudoceramide Improved Both Skin and Hair Barrier Functions

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 conversation discusses using peptides BPC-157 and TB-500, combined with microneedling, to potentially enhance hair regrowth. The user plans to try BPC-157 due to its lower cost and reports of hair growth, despite limited human trials and concerns about side effects from other treatments like minoxidil and finasteride.

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.

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 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.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.
