Dandruff, one of the oldest tales in the book. It is caused by a fungus called Malassezia which grows on the scalp and makes the skin damaged and very dry. However, there is also another type of dandruff that causes the scalp to start producing oil and thus appearing sticky and oily on the hair.
Some of the practices that can cause dandruff include irregular washing and brushing of hair, not using the correct shampoo, Parkinson’s disease amongst others.
