The signs of an allergic reaction to hair products are typically characterized by skin responses rather than hair alterations. Redness, swelling, itchiness, or blistering on the scalp are specific manifestations of an allergic reaction. These symptoms occur when an individual's immune system reacts adversely to certain ingredients found in hair products, such as dyes, fragrances, or preservatives.

In contrast, persistent hair fall and dryness may result from various hair care practices or damage but do not specifically indicate an allergy. Frizziness and a hard texture can also stem from product build-up, environmental factors, or improper hair care techniques rather than an allergic response. Changes in hair color could occur due to the use of hair dyes but are unrelated to an allergic reaction, as this would involve a different type of chemical reaction, not an immune response. Therefore, the distinctive symptoms associated with allergies are clearly articulated in the correct choice.
