Ayurveda and Dandruff Ayurveda places the problem of dandruff in the category of Shudra Roga-Darunakam which appears due to an imbalance of all three doshas (Ayurvedic humor). The primary doshas involved are Pitta and Vata. In an aggravated state, both doshas cause production of specific impurities, called ama, which are dry and heating in nature. These impurities accumulate in the deep tissues of scalp and contaminate them. Contamination of the deep tissues and aggravated Vata-Pitta Dosha cause itching and patches on scalp. Due to these factors, the scalp sheds larger than normal amounts of dead epidermal cells, which leads to the problem of dandruff.
