Can Kerablak Hair Serum turn white hair back to black?
Kerablak Hair Serum claims to naturally restore hair colour, but there is no scientific evidence proving it can fully turn white hair back to black. While it may help slow further greying or improve hair health, reversing white hair to its original colour is not guaranteed. The effectiveness depends on factors such as genetics, age, overall health, diet, lifestyle, and environmental factors. For personalised advice and realistic expectations, it's advised to consult a trichologist.
