The signs of an allergic reaction to a hair product typically include redness, itching, swelling, and hives. These symptoms arise as the body produces an immune response to a substance it recognizes as harmful, even if the substance itself is not inherently dangerous. When a person applies a product that contains allergens, their skin may react by becoming inflamed, resulting in noticeable redness and swelling. Itching often accompanies this inflammation as the body signals discomfort and irritation. Hives, or raised welts on the skin, can further indicate a more severe allergic reaction.

In contrast, smooth skin and glossy hair do not indicate an allergic reaction; instead, they may suggest that a product is effective in enhancing the appearance of hair and skin. Dryness and hair breakage point to damage rather than an immune response. Lastly, excess oil production can be a reaction to certain products but does not align with the immediate hypersensitivity response typical of allergies, which is characterized by the symptoms mentioned. Thus, the symptoms listed in the correct response directly relate to how the body typically reacts to an allergen in hair products.
