I've noticed that so many hair products have protein in them. For those that use Sta-Sof-Fro, or others who use gels with protein, how do you think it is effecting your hair? Is there enough protein in these products to cause problems? I'm curious because I really love Giovanni Direct Leave and it has soybean protein in it. It is way down on the list of ingredients, but I'm concerned about using it every day. Also, what about amino acids. I have a conditioner that I like to use for deep treatments (moisturizing) but it has amino acids in it. It doesn't leave my hair hard at all, like infusium did, but still....???
