NHS Choices Condition

It is important to note that dandruff, or seborrhoeic dermatitis of the scalp, is not caused by poor hygiene. The exact cause is unknown, but there are a number of suggestions.
Not brushing your hair regularly may lead to dandruff because the dead skin cells are not able to shed properly.
Certain natural yeasts that are produced by your body may also cause dandruff to occur. The condition may develop if your body is sensitive to the yeast.
If this is the case, you may find that your dandruff improves during warmer months, and gets worse during colder months. This is because the UVA light from the sun counteracts the yeast.
