A common sign of an allergic reaction to hair color is indeed redness and itching on the scalp. This occurs because hair dyes often contain chemicals that can irritate the skin or trigger an immune response in sensitive individuals. When someone develops an allergic reaction, the body's immune system identifies substances in the dye as harmful, leading to symptoms like inflammation, redness, and intense itching.

Recognizing this reaction is crucial for both the barber and the client, as it can lead to further complications if not addressed. The presence of redness and itching serves as a direct indicator that the client may be having an adverse reaction to the hair color product, prompting the need for immediate action, such as rinsing the dye out and possibly applying soothing treatments.

In contrast, dry hair, oiliness of hair, and increased hair growth are not typical indicators of an allergic reaction. Dry hair might be a sign of product buildup or damage rather than an immune response, oiliness of hair usually results from excess sebum production, and increased hair growth is unrelated to reactions to hair color. Thus, understanding the specific signs of allergic reactions can help prevent severe dermatological issues and provide safer services in the barbering industry.
