You can do hair softening like a hair salon! One step solution! I suggest you use something called "wake-up water"! That pair of bristles is better! At present, I only know that Mei Tao, Sassoon and Jesuits (Jesuits, not Jesuits) have produced such things! Attention! Don't use germanium! ! ! There are also hair care products with high styling (that will make your hair more and more fried)!
