Question: 1 / 400

What are common causes of dandruff?

Excessive washing

Dry skin and sensitivity to products

Dandruff is commonly caused by dry skin and sensitivity to hair care products. When the scalp becomes overly dry, it can lead to flaking, which manifests as dandruff. Additionally, some individuals may have a sensitivity or allergic reaction to certain ingredients found in shampoos, conditioners, or styling products, which can irritate the scalp and contribute to the flaking.

While excessive washing can strip natural oils from the scalp, it is not as directly linked to dandruff as dry skin is. Similarly, heat styling and having long hair do not directly cause dandruff; they may contribute to overall hair health or scalp condition but are not primary factors in the development of dandruff. Therefore, understanding the relationship between dry skin, product sensitivity, and dandruff is crucial in addressing and managing this common scalp condition.
