Fevi 2019, Seti 2021. Seti is being trialed for mbp right now, fevi is being trialed for asthma but in theory should work better than Seti. As far as knowing if it will work, it appears that it is excellent for maintenece and thickening but probabaly won’t regrow much hair. The problem is that fibrosis occurs in areas that have been bald for a while. It is very hard for hair to grow in those areas. You’d probably get pretty decent regrowth with a Seti, minoxidil, and wounding regimen. That’s what I’ll be starting soon when my Seti arrives.
