What type of scalp condition is characterized by redness and inflammation?

The condition characterized by redness and inflammation of the scalp is seborrheic dermatitis. This condition presents with symptoms like red, inflamed skin, often accompanied by oily or flaky patches. Seborrheic dermatitis can create an environment conducive to the overgrowth of yeast on the skin, which can exacerbate the inflammation and lead to increased flaking.

Psoriasis, while also a condition that can affect the scalp and cause redness, is typically characterized by raised, thick, silvery scales and is part of a broader systemic condition involving the immune response. Dandruff is usually associated with flaking and may involve some mild redness, but it doesn’t typically present significant inflammation. Alopecia refers to hair loss and does not inherently involve a specific inflammatory response or redness of the scalp.
