Is it true that the mystery of black turns from white to black?

Yes The effect of turning black and white is mainly achieved by applying something similar to hair dye to the hair, but it can't fundamentally treat white hair, which may be caused by congenital genetic factors, deficiency of qi and blood, and physical weakness. Black mystery products and physical therapy services mainly improve the scalp environment and hair follicle conditions, so as to achieve the effect of turning white hair into black.
