The symptoms of an allergic reaction to hair dye typically include redness, itching, and swelling. These manifestations occur due to the skin's immune response to allergens present in the hair dye, such as para-phenylenediamine (PPD) or other chemical components. When a person who is sensitive to these substances applies hair dye, their body may react by causing inflammation and discomfort in the affected areas, often leading to visible redness and itching. This is the body's way of signaling that it is reacting to a foreign substance, and in some cases, it can also lead to swelling around the application site.

The other options mentioned, while they might represent issues related to hair or scalp health, do not specifically indicate an allergic reaction to hair dye. For example, dryness, split ends, and frizz are often related to the hair's condition rather than an allergic response. Dandruff and irritation could suggest a variety of scalp issues, but do not specifically point to an allergic reaction. Uncontrollable hair growth is not associated with allergic responses associated with hair dye; rather, it's a hormonal or genetic condition that would not be triggered by typical hair treatments. Thus, the symptoms listed in the correct answer are directly indicative of an allergic reaction.
