TLDR Lipids in Japanese hair help maintain glossiness and structure.

The study analyzed the lipid content in the medulla of Japanese hair, revealing that it contained unsaturated lipids, which decreased from the root to the tip. This reduction correlated with decreased hair glossiness, suggesting that these lipids contribute to glossiness. Thin-layer chromatography (TLC) and micro-attenuated total reflectance Fourier-transform infrared spectrophotometry (micro-ATR FTIR) identified squalene and oleic acid as key components of the medulla. The presence of these lipids was linked to the maintenance of the medulla, highlighting their importance in hair structure and appearance.

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.

community Does melatonin dissolve in isopropyl alcohol

in Technology 7 upvotes 2 years ago

The conversation discusses making a topical melatonin solution for hair loss treatment, questioning if isopropyl alcohol can dissolve melatonin. Melatonin is soluble in lipids and alcohol, but it's unstable and should be mixed fresh regularly; it may help hair growth by affecting certain cellular signaling pathways and has anti-androgenic effects.
