Softening is an important step in straightening. Softening is the process of applying medicine to hair without splint. After applying the potion, straighten it with an electric splint. This is called ion ironing.
If the hair is particularly thick, softening will not keep the hair for a long time, or you can choose to let the hair straighten naturally, which can obviously improve the current situation of the hair.
