Stress, pollution, hormonal imbalances, certain medicinal treatments and the use of unsuitable hair products can contribute to the appearance of dandruff. These various factors cause the spread of a yeast called Malassezia furfur, which created an imbalance in the scalp and triggers irritations and itching. This can lead to two types of dandruff: Dry dandruff: fine, white or greyish flakes. Not adherent to the scalp, these flakes detach themselves spontaneously and fall "like dust" onto the shoulders. Oily dandruff: these large, yellowish, oily, thick flakes stick to the scalp because the condition is accompanied by hyperseborrhea of the scalp.
