Your scalp state has a great impact on hair strength. If you have an oily scalp, then there is a chance for getting dandruff. An oily scalp can be caused by the overactive sebaceous gland on the scalp. It may lead to excessive shiny hair. Oil content in your hair attracts dirt easily and make it very sticky. It may result in dandruff. My cousin also had faced this problem and lost his hair. Then he had a hair loss surgery in Toronto for volumizing his hair. But due to his oily scalp, he had faced a dandruff problem even after his surgery. This made him desperate and sought the help of his doctor. The doctor referred him a medicated shampoo for daily usage. And now he is free from dandruff problem.
