Is it true that doctor's garden changed from white hair to black hair?

Fake. Doctor Garden is a company specializing in plant hair care and hair growth products. Its products and methods of turning white hair into black hair mainly rely on hair dyes and some ingredients that claim to promote hair health and growth. These products and methods have not been scientifically proved to really turn white hair into black hair. The formation of white hair is due to the fact that with the increase of age, melanocytes in hair follicles gradually reduce or stop producing melanin, which makes the melanin in hair decrease or not produce, thus forming white hair. At present, there is no scientific method to reverse this process and make the white hair turn black again. Therefore, it is false for the doctor's garden to turn white hair into black hair.
