Dandruff is flaking of scalp (and othe areas on the skin) which is often accompanied by itching. Dandruff is not the direct cause of hair loss but itchiness leads to scratching which can injure the hair follicles and lead to some hair loss. One main cause of dandruff is seborrheic dermatitis. Seborrheic dermatisis is the occurrence of red and greasy (oily) skin that is covered in flaky white or yellow scales. These white flakes are clusters of dead skin cells. Dandruff occurs due sensitivity due to some hair products (unsuitable), skin conditions such as dry skin, eczema, etc, overgrowth of a yeast-like fungus, pollution, etc. Shampoo with pyrinthione zinc, salicylic acid, ketoconazole, selenium sulfide, etc helps to reduce dandruff.
Dandruff is a common condition that causes flaky skin on the scalp. This skin often falls off, leaving white flakes on your hair and shoulders. Generally, dandruff doesn't directly cause any hair loss. However, dandruff is associated with itchiness in many cases. The itchiness causes a person to scratch the head which causes hair fall. But psoriasis, which is a skin condition with similar symptoms, can cause hair loss. Therefore, it is important to talk to a doctor to confirm whether it is dandruff or something else.

But they both are different conditions and require different treatment. In most cases, dandruff symptoms include white, oily-looking flakes of dead skin that fall on your hair and shoulders, and may also be associated with an itchy and scaly scalp.
