Hi Kumaresan, Welcome to HealthcareMagic Forum.
Does anybody else in your family have the same problem? If yes, then it is hereditary. You will have to get yourself examined by a Dermatologist
as you may need hair solution which you have to apply it as you apply hair oil twice daily. Eat protein rich food which should include Milk, Fish, chicken, Eggs, Lentils, fresh fruits and green veggies. Avoid stress
and use a Helmet while riding a Bike. Do not have head bath for more than twice a week.
