Why is dandruff occur when there is extreme temperature?

Dandruff can occur in extreme temperatures due to changes in humidity and scalp oil production. Cold weather often leads to dry air, which can cause the scalp to lose moisture, resulting in flakiness. Conversely, excessive heat can stimulate the scalp's oil glands, leading to an overproduction of oil and a buildup of dead skin cells, both of which contribute to dandruff. Additionally, temperature fluctuations may also affect the scalp's microbiome, potentially exacerbating dandruff conditions.
