Sudden greying of beard and chin hair at a young age can be due to factors like genetics, stress, or nutritional deficiencies (especially Vitamin B12, iron, or thyroid imbalance). Sometimes, lifestyle factors like poor diet, smoking, or lack of sleep can also contribute. While it is difficult to reverse already grey hair naturally, you can slow further greying by improving your diet (including protein, green vegetables, nuts, and fruits), managing stress, and maintaining good sleep.

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.

Premature greying can sometimes be linked to nutritional deficiencies, especially low Vitamin B12, iron, calcium, or thyroid issues, but it can also be genetic or stress-related. In many cases, fully reversing grey hair is difficult, but improving your diet (with protein, green vegetables, nuts, and fruits) and correcting deficiencies may slow further greying. It is a good idea to get blood tests like Vitamin B12, iron levels, and thyroid function checked. If a deficiency is found, proper treatment may help improve hair health and prevent further greying.
