Dandruff is most commonly observed during the winter months due to several contributing factors. The cold weather associated with winter often leads to dryness in the air, which can cause the skin, including the scalp, to become dry and flaky. This lack of moisture is a significant factor that exacerbates dandruff conditions, as a dry scalp can lead to increased flaking and irritation.

Additionally, people tend to use indoor heating during the winter which further reduces humidity levels, contributing to dryness not only in the environment but also on the skin and scalp. Wearing hats and other head coverings, common in winter, can also trap heat and moisture, leading to a buildup of oils and dead skin cells, which may worsen dandruff.

In contrast, the other seasons may not see the same levels of dryness or the environmental factors that contribute to the problem, making winter a prime time for dandruff to flourish.
