MCL-1 is important for hair follicle stem cell survival, but its impact on human hair regrowth is unclear. Minoxidil and finasteride are the main treatments, with doubts about new discoveries leading to effective human solutions soon.
A new alcohol-free, propylene glycol-free topical finasteride foam is available for prescription in Canada and the USA, offering a cleaner alternative for hair loss treatment. The product also offers a combination of 0.1% finasteride with 5% minoxidil and aims to be affordable and less irritating for sensitive scalps.
Aminexil/Kopexil may help reduce hair loss by addressing perifollicular fibrosis in androgenetic alopecia, but it lacks the extensive clinical backing of finasteride and minoxidil. Some users find it effective, but availability and cost are issues, especially in the US where it's not FDA-approved.
