Small, white scales appearing on the scalp and hair indicate:

1. Keratosis Pilaris

2. Pityriasis

3. Psoriasis

4. Eczema

The correct answer is: Pityriasis

Small, white scales appearing on the scalp and hair are indicative of pityriasis, a common skin condition caused by excessive shedding of dead skin cells. This condition is often seen in areas with a lot of hair follicles, such as the scalp, and can be accompanied by red, itchy patches. The other options may also cause similar symptoms, but they are not specifically associated with small, white scales on the scalp and hair. Keratosis pilaris is a skin condition characterized by small, rough bumps on the skin, commonly found on the arms and thighs. Psoriasis is a chronic autoimmune condition that causes red, scaly patches on the skin, typically on the elbows, knees, and scalp. Eczema, also known as atopic dermatitis, is a condition that causes red, itchy, and inflamed patches on the skin, and can occur anywhere on the body. In summary, while all of the options may present with some similar symptoms, pityriasis specifically describes the presence of small, white scales on the scalp and hair.
