What is the most common cause of scalp irritation in clients?

The most common cause of scalp irritation in clients is often related to allergic reactions to hair products. Many hair care products contain various chemicals, fragrances, and preservatives that can trigger sensitivities in some individuals. When clients experience irritation, it may manifest as redness, itching, or inflammation of the scalp, which is typically a response to the ingredients in the products used.

While excessive heat exposure, frequent chemical treatments, and dry scalp conditions can contribute to scalp discomfort, they are less frequently the primary cause compared to allergic reactions. Heat can lead to dryness or exacerbate existing conditions but does not typically result in an allergic response. Frequent chemical treatments can also cause irritation, but the result is often due to damage rather than an allergy. Dry scalp conditions are a common concern but are usually not classified under irritation caused by products. Overall, the prevalence of product allergies makes it the most common cause of scalp irritation among clients.
