Does anyone know of a good and healthy hair relaxer for woman of color?

affirm fiberguard is suppose to be good, but you have to buy the whole system to get the full effect. I prefer Mizani, and some think Phytospecific is a healthy system, but its pricey $60 for one kit and at the salon they'll charge $80+ for that brand.Does anyone know of a good and healthy hair relaxer for woman of color?
