I'm back...trying all my BF products.
Camille Rose Naturals Nangai &Tsubaki Strength Restore Protein Treatment is possibly holy grail.
It was just as amazing (actually better) as the Hydrathermal Naturals treatment...it made my curls pop in a way I've never seen.
For reference, I'm 4a/3c, high porosity, fine strands, very high density and my hair loves protein.
