2. Dandruff or itchy scalp

3. Oily hair

4. Split ends

The correct answer is: Dandruff or itchy scalp

A common sign of product build-up on the scalp is the presence of dandruff or an itchy scalp. When hair care products such as gels, sprays, and conditioners accumulate on the scalp without being adequately cleaned off, they can irritate the scalp's surface. This irritation may lead to flaking, which resembles dandruff, and can also cause itchiness as the scalp reacts to the excess residue. Product build-up can result from using too much product, not clarifying the hair regularly, or using products that are not designed for a specific hair type. Often, the buildup can hinder the natural processes of the scalp and hair, resulting in an uncomfortable and unhealthy condition. Addressing this issue typically involves using a clarifying shampoo or an exfoliating treatment to help remove the layers of product residue and restore scalp health. While dryness, oily hair, and split ends can indicate various scalp or hair issues, they are not as directly associated with product build-up itself. Dryness may result from lack of moisture, oily hair is often a sign of excess sebum production, and split ends are typically caused by environmental factors or damage to the hair shaft rather than product accumulation.
