Relieving an itchy, irritated scalp
There are no scientific studies that show a direct link between stress, diet and dandruff.
Should you keep an eye on the weather forecast? Maybe, weather does not cause dandruff, but it may make it more obvious. Less humidity in the air can lead to a reduced amount of oil on the scalp, which may keep flakes from sticking. Because they are being shed more readily, the flakes become more visible throughout the hair.
