Unpopular opinion: keratin treatments are way overhyped for most hair types
I kept hearing how keratin would save every frizzy head, so I finally tried it on a client last month. Turns out, the stats from a 2023 survey by Professional Beauty Association say 68% of clients with fine hair ended up with damage or breakage within 6 months. I found that number buried in a trade article about ingredient safety. Don't get me wrong, they work great for coarse, thick hair in my experience. But for the average person with medium density hair, I think we push these as a fix-all too much. Has anyone else seen more split ends or thinning after doing these treatments on clients?
