Human Essential Fatty Acid Deficiency: Treatment by Topical Application of Linoleic Acid

Excess sebum rich in cholesterol and triglycerides can lead to hair loss through inflammation, with treatments like Ciclopirox shampoo, Benzoyl Peroxide shampoo, and Clindamycin gel recommended for managing conditions like seborrheic dermatitis and folliculitis. Pioglitazone is suggested for Lichen Planopilaris, while Omega-3s and reducing processed foods may improve sebum quality, though genetic factors play a significant role.

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.

A user is experiencing hair thinning and is using a peptide with oleanic acid as a DHT blocker, along with minoxidil, while waiting for topical finasteride. They plan to use a combination of minoxidil, finasteride, dermastamp, ketoconazole, and scalp massages, but are advised to stick to proven treatments like finasteride and minoxidil.

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.

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.

Excessive scalp sebum, worsened by DHT, can lead to inflammation and hair loss, with clascoterone mentioned as a treatment. Diet changes seem ineffective for scalp sebum, and treatments like minoxidil and finasteride are suggested.
