Though dandruff does not cause hair fall, when it is left untreated, your scalp can become so itchy and inflamed that it can cause temporary hair loss. You can keep dandruff at bay by following a good haircare regime, by using home remedies and anti dandruff shampoos. However, if the symptoms persist and you feel that it could be a medical condition, such as seborrheic dermatitis, psoriasis, fungal infections, you should consult a dermatologist.
