A staple!!!
My hair has never been this strong in my entire life! I can pull on my strands and they won’t budge. I have fine/medium 3c/4a hair that I flat iron weekly and I get a keratin treatment once a year. I’m a snob about haircare so when I say this is amazing i mean it. Use conditioner though.
