What is the reason for so much dandruff in winter?

There may be many reasons for dandruff in winter:

Dry scalp: factors such as low temperature and low air humidity may lead to dry scalp. This will make the cuticle of the scalp thinner and lose its luster, and it will easily fall off to form dandruff.

Too frequent or incomplete shampooing: Too frequent or incomplete shampooing will stimulate the scalp, causing the cuticle of the scalp to fall off and form dandruff.

Excessive secretion of scalp oil: when the temperature is low in winter, the secretion of human oil will decrease accordingly. If the scalp oil is secreted too much, it will lead to greasy scalp and promote the growth of dandruff.

Mental stress: excessive mental stress will affect the body's immunity and may lead to an increase in dandruff.

Health problems: Dandruff may also be a sign of a health problem. Such as scalp allergy, fungal infection and so on.

It is suggested to pay attention to scalp health at ordinary times, clean hair moderately, adjust diet, avoid excessive anxiety and stress, and consult a doctor for treatment if necessary.
