Itching and redness are hallmark symptoms of scalp irritation, typically indicating that the skin has become inflamed or is reacting to an irritant. Scalp irritation can result from various factors such as allergic reactions to hair products, excessive scrubbing, or skin conditions like dermatitis. The sensation of itching often accompanies redness, as both signal inflammation and discomfort in the affected area.

While excessive oiliness, dry and flaky skin, and color loss can relate to other scalp and hair conditions, they do not directly signal irritation in the same way that itching and redness do. For example, excessive oiliness might indicate overactive sebaceous glands, and dry, flaky skin might be associated with different conditions like psoriasis or dandruff rather than irritation specifically. Color loss in hair may relate to chemical exposure or other health issues, rather than being a direct symptom of scalp irritation. Thus, itching and redness stand out as the most common and direct indicators of scalp irritation.
