Other skin conditions, like very dry skin, eczema, itchy scalp, malassezia (yeast infection), and psoriasis can also cause a scaly scalp and dandruff symptoms. Very often, it is related to hair loss. This is because an individual with this problem tends to scratch the scalp frequently, which at times, leads to uprooting of the hair from the follicles. With correct hair care and natural remedies, scaling of the scalp can be treated. One such effective remedy is applying the diluted form of vinegar on the scalp, which helps restore the acid-base balance in the scalp.
