The condition that may cause the scalp to become itchy and flaky is seborrheic dermatitis. This skin disorder is characterized by red, greasy patches covered with flaky white or yellow scales. It most commonly affects areas of the body where the glands that produce oil are concentrated, such as the scalp. The itchiness and flakiness can result from the overproduction of oil and the presence of yeast that thrives on this oil. Seborrheic dermatitis can be triggered by factors such as stress, hormonal changes, or certain weather conditions.

Dandruff, while also causing flakiness, typically doesn't present with the same level of redness or inflammation seen in seborrheic dermatitis. It is often milder and may not involve as much oil or sensitivity. Psoriasis is another skin condition that may cause flakiness and itchiness, but it typically has more defined, thick, silvery scales and is associated with rapid skin cell turnover. Allergic reactions can cause itching and flaking, but they tend to present with acute symptoms rather than the chronic condition associated with seborrheic dermatitis.
