Hair Whitening Problem
As explained below
Hello, and welcome to 'Ask A Doctor'
Thanks for posting your query.
Hair whitening is usually hereditary or vitamin deficiency. You can take
Tab. Revilus once a day for 3 to 4 months.
Tab. Kerablak once a day for 3 months
You can also get some blood tests done to rule out other conditions such as haemoglobin level, and thyroid profile
I hope this helps. Please feel free to discuss further if any.
