Scalp irritation can be caused by a variety of factors. Some of the most common include dandruff, lice and contact dermatitis.

Dandruff is a problem caused by a yeast-like fungus called Malassezia, which thrives on oleic acid, an oil found in your scalp buildup shampoo. These oils can cause your skin to shed faster than usual and build up into clumps of dead skin cells, which form visible white dandruff flakes.

Regular shampooing is a key treatment for dandruff. It removes the dandruff flakes as quickly as they form, and can also help to control the production of oleic acid.

Contact Dermatitis

Some shampoos and hair dyes contain ingredients that can irritate your skin, which can lead to a itchy, red rash. This is known as contact dermatitis.

Irritant contact dermatitis can occur after a single exposure to a strong irritant, or after repeated use of a mild irritant. It may also develop after exposure to a substance that enters your body through food, flavorings or medicines (systemic contact dermatitis).

Allergic contact dermatitis is triggered by an overreaction of the immune system to a particular substance, which often comes from a plant, a pet, a drug, or a product in your home. This reaction affects only the area of skin that was in contact with the allergen.

Itching of the scalp is the most common symptom, but it may not happen right away. A rash is also possible.
