Have you ever experienced itching and then discovering white flakes on the upper part of your clothes? This is a very irritating and embarrassing dilemma that anyone could experience. Dandruff is a condition of the scalp that is caused by malassezia fungus or pityrosporum. This is part of the normal flora that naturally grows on your scalp. But due to illness, excessive sebum, stress, hormonal imbalances, suppressed immunity, and inefficient washing, this organism causes inflammation that yields excessive skin cells. The dead skin cells combine with oils and cluster together and are seen as white flakes.
