Redness and itching are key symptoms indicative of scalp irritation. These signs often suggest an inflammatory response, which could be triggered by various factors such as allergic reactions to products, environmental conditions, or underlying skin conditions like dermatitis. When the scalp is irritated, it becomes inflamed, leading to visible redness, and the sensation of itching can result from nerve endings becoming sensitized in the irritated area.

In contrast, while other symptoms like excessive oil production, flaking, and hair splitting might be related to scalp health, they do not specifically signify irritation in the same way. A change in hair growth rate may indicate a different underlying issue, such as nutritional deficiencies or hormonal changes, rather than direct scalp irritation. Therefore, redness and itching are the most direct symptoms that reflect irritation of the scalp.
