After much trial and error and discovering that many products caused scalp issues and weighed my hair down, I only use Natures Gate shampoo/conditioner (mostly the Biotin, Daily Herbal & Pomegranate Sunflower) and Marie Dean Mango Cupuacu Hair Pudding (protein free) which I scrunch in. And once or twice a month SS protein spray which is a leave in.
Today I used Mop C moisturing shampoo and the MD pudding and there was definitely an improvement in the frizzy tangles.
That's why I suspect the NG products which if I am reading the labels correctly are loaded with different types of proteins...including Panthenol, Hydrolyzed Soy Protein, and Hydrolyzed Vegetable Protein.
