In order to get rid of the harm of chemical hair dye to human body, medical scholars have developed five-shell hair dye for a long time by using nanotechnology and coagulation patent technology after years of research. Galla Chinensis hair dye is made of pure natural ingredients and does not contain harmful substances such as lead, mercury and p-phenylenediamine.
Gallnut hair dye will open the hair scales when it comes into contact with hair, and complete the coloring process and close the hair scales within 15 minutes. After dyeing, the hair is dark and bright, and it can be washed for 45 times, which is quite rare for a natural product.
