I gave him shampoo that turned from white to black. My parents are now in their forties, almost five. I think what saddens my children most is that their omnipotent parents have turned gray. I used to dye my father's hair several times at home, but in recent years, with the gradual improvement of "health awareness", parents paid more and more attention to health and began to resist hair dyes! This is a good thing. I told my parents not to dye their hair before, but they wouldn't listen for fear that they would look old. But I can still feel that my parents are very concerned about their white hair every day, and they are not completely at ease, so I bought this set. It is said that the effect will be obvious after they use it for almost three months.
