There is no reliable safety information available on the use of Kerablak Hair Serum in children. For any specific hair or scalp concerns in children, it is advised to consult a doctor or paediatrician, and do not use this or any similar product on your own in a child without proper medical guidance.

No, you don’t need to wash your hair before each use. Just apply the serum once a day and leave it on your scalp. For the best effect, it’s good if your scalp is reasonably clean, but a full wash every time isn’t necessary.

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.
