A common cause of scalp irritation during a hair treatment is an allergic reaction or chemical burns from products. Many hair treatments involve the use of various chemicals, such as dyes, relaxers, and treatments designed to alter the hair structure. These substances can sometimes provoke an allergic response in some individuals, resulting in redness, itching, or other inflammatory reactions on the scalp. Additionally, if these products are applied improperly or left on longer than recommended, they can cause chemical burns, leading to further irritation.

The other options do not typically lead to significant scalp irritation in the context of hair treatments. Excessive washing before treatment is usually not harmful to the scalp, although it could strip away natural oils. Exposure to excessive heat can potentially cause damage to hair but is less likely to cause scalp irritation compared to chemical reactions. Using water that is too cold is generally a matter of personal preference and unlikely to cause irritation; rather, it can affect the overall comfort of the treatment experience. Therefore, allergic reactions and chemical burns remain the primary concerns in scalp irritation during hair treatments.
