Firstly, I feel I must explain my hair type. I have naturally curly hair that, when dried naturally without any products, is extremely frizzy and poofy, with deep waves at the crown of my scalp. However, it is not dry or brittle, in any way. When it dries, the curls don't define, rather they just look as though I touched a power outlet, then brushed it while dry. That being the case, I tried everything. Plain Moroccan Argon Oil, serums, Keratin treatments, you name it, it's been tested on this hair. I have even tried using products for women of color, ( I am Caucasian), which did not work for me either. One day I was in the grocery store and came across this and thought I would give it a try. That was about 6-7 years ago, and I have not used another thing since! After I get out of the shower, I apply it generously going from ends to roots (I have thick, long hair) and it dries leaving my curls defined, no frizz whatsoever, and absolutely no oily/greasy residue on my scalp! It smells awesome, too, which is a plus. As long as this product is on the market, I will not buy anything else.
