"Dandruff is common condition that causes flaky skin on your scalp. In most cases, dandruff doesn't directly cause hair loss. However, the itchiness it causes can lead to scratching. This can injure your hair follicles, leading to some hair loss, though not complete baldness. The main cause of dandruff is seborrheic dermatitis, a condition that turns the skin oily, red, and scaly. ... Often, a fungus called malassezia triggers dandruff. This fungus normally lives on your scalp. Many factors can cause dandruff, such as dry skin, diet, stress, and some shampoos and hair products. Repeated inflammation in the hair follicles can cause damage and scarring, slowing or stopping hair growth. This can cause weak or thinning hair. Twisting the hair, aggressively brushing it, or scratching the scalp may make this type of hair loss worse. Scalpid drops helps to remove dandruff or related issue very effectively. "
