4-Hydroxynonenal, a Lipid Peroxidation Product, Inhibits Glutathione Peroxidase: Protective Effect of Glutathione

Selenium sulfide shampoo helped with a sore scalp but may cause hair root damage. Users experienced hair loss with selenium sulfide and ketoconazole, suggesting reducing use if hair loss occurs.

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.

A Spanish dermatologist suggests sulforaphane for androgenetic alopecia (AGA) due to its potential to remove DHT metabolites, though high dosages are needed. A topical formulation might be possible.

Rotenone, a natural plant extract, may promote hair growth by increasing LDH activity and blocking MPC in the scalp, but it carries risks due to its toxicity. The suggested formulation includes Barbasco extract, DMSO, propylene glycol or PEG-400, ethanol, and a carrier oil.

The conversation discusses using NAC and quercetin as supplements for hair loss, with some users also mentioning finasteride. NAC is highlighted for its potential benefits, but concerns about its safety and absorption are also raised.

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.
