I have fine 3b curls and was told that my hair should like protein. However, after a couple of years, I think my hair needed a protein break. My hair started to feel like straw, got knotty, was frizzy and my curls were limp. I had been using a conditioner with protein as well as gel with lots of sea proteins. I switched my products so that only my co-wash contained protein -- everything else is protein-free and my hair is much happier. My current line-up:
Low poo - Mop C Hydrating (once a week)
Co-wash - Renpure Organics body & shine (green bottle) conditioner
Conditioner - Garnier Fructis Sleek & Shine NEW FORMULA with no cones
Leave-in conditioner - Garnier Sleek & Shine
Gel - Garnier Fructis Pure Clean Gel

Good luck!
