A common cause of scalp irritation is an allergic reaction to hair products. Many hair care products contain various chemicals, fragrances, or preservatives that can provoke sensitivity in some individuals. These reactions may manifest as redness, itching, flaking, or even swelling of the scalp. Identifying triggers is essential for individuals with sensitive skin or allergies, as it can lead to the selection of more suitable products that are free from irritating ingredients.

While overuse of hair conditioner can lead to buildup on the scalp, which might cause irritation, it is less specific than an allergic reaction. Cold weather can also impact skin health but is generally not a primary cause of scalp irritation. Improper hair washing techniques may lead to oil and dirt buildup, also contributing to irritation, but again, it does not directly compare to the specific physiological response that occurs with an allergic reaction. Understanding these various potential causes helps in managing and preventing scalp irritation effectively.
