Weather is a factor when it comes to having dandruff so we need to take extra care of our scalp. Sunny and warm days can make us sweat more, while on rainy days, high humidity can increase moisture and oil on the scalp. Both can lead to the overgrowth of Malassezia globosa, a yeast-like fungus that thrives on scalp oils, causing the scalp to overreact and produce those white flakes.
