Can washing your hair once a week cause dandruff?


    If you assume your dandruff is due to a dry scalp, it might be tempting to cut back on washing it so often. But whether the cause is dryness or oiliness, you should be washing your hair pretty regularly to rinse away the flakes and buildup of debris on your scalp. If your scalp is too dry, it can cause flaking, itchiness, and even skin peeling. Having an oily scalp can also be a factor. Yeast can also feed on the oil on your scalp, which can cause an inflammatory response in some. The fungus occurs naturally in healthy scalps, but if allowed to overgrow, it can result in problems for some.
