Welcome and thanks for posting your query to HealthcareMagic.
As per your query you have the problem of white hair over scalp
and chest with "male pattern baldness".
It is a common phenomenon in all males to have hair fall
and a pattern of hair loss because of the hormonal
influence. This also depends on the genetical factors form your parent's side.
I can understand your concern for the same. But you should understand that it is quite a natural phenomenon rather than any disease process or any illness which leads to greying of the hair.
Generally the greying begins by the age post 30 years. You are 29 years means you are close to that particular age. There are so many reasons for the white hair problem, but not a single one reason is close enough to tell the exact truth. Generally we consider it as aging process sooner or later.
We usually prescribe Vitamin B complex especially Pantothenic acid
to eat by mouth for multiple months. Though three are variable results but is the only oral therapy
Recently the product containing Melitaine is claiming good results can also be with tried. your doctor has very correctly prescribed the same.
Over all improve your diet with fruits and green leafy vegetables, stop any substance abuse
and reduce your stress
I hope these information's will help you. If you have further queries I will be happy to help.
