Psoriasis

Psoriasis is a chronic autoimmune condition that can cause skin cells to grow too quickly, resulting in thick, scaly patches on the scalp and other areas of the body. In addition to scaling, scalp psoriasis can also cause itching and inflammation.

Seborrheic Dermatitis

Seborrheic dermatitis is a common skin condition that can cause yellow or white scales to form on the scalp. This condition is caused by an overgrowth of yeast on the skin and can also cause itching and redness on the scalp.

Hair Dye Allergy

Hair dye allergy is a common condition that can cause an itchy rash to form on the scalp and other areas of the body. This condition is caused by an allergic reaction to the chemicals found in hair dye products.
