What is a common allergic reaction related to hair products used in braiding?

A common allergic reaction associated with hair products used in braiding is contact dermatitis, particularly stemming from the use of hair dyes or adhesives. Contact dermatitis is a skin condition characterized by redness, itching, and swelling, which occurs when the skin comes into direct contact with allergens or irritants. Many hair dyes contain chemicals such as paraphenylenediamine (PPD) and other reactive components that can provoke an immune response in sensitive individuals.

Adhesives used in hair applications, including braiding, can also contain various irritants that might cause similar reactions. These irritants penetrate the skin barrier, triggering the immune system to respond, leading to the symptoms of contact dermatitis.

While headaches, swelling of the scalp, and increased oiliness of hair can occur due to various factors, they are not direct allergic reactions related to the application of hair products. Those conditions might stem from other sources, such as tension from braiding or changes in sebum production, rather than an allergy. Therefore, contact dermatitis from hair dyes or adhesives represents a well-documented allergic response that can manifest in individuals exposed to these products during braiding.
