The Role of Linoleic Acid in Skin and Hair Health: A Review

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.

Oleic acid and microneedling are being explored for hair regrowth, but results are mixed. Addressing DHT and fibrosis is crucial, with treatments like finasteride, minoxidil, and scalp massage also discussed.

Carnosic acid in rosemary extract may enhance skin repair and promote hair follicle regeneration. It could be used alone or with verteporfin for scarless healing after dermal wounding.

Oleic acid and ethanol are being considered for hair regrowth, with some users planning to self-experiment. There is skepticism about their effectiveness, and ongoing use of treatments like finasteride and minoxidil is mentioned.

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.

The conversation discusses the potential of long-chain unsaturated fatty acids, like oleic and linoleic acid, as an additional treatment for hair loss, which may inhibit the enzyme responsible for converting testosterone to DHT and promote hair growth. Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.
