Chemical hair treatments often involve the use of strong substances that can alter the structure of the hair and scalp. One of the most significant risks associated with these treatments is skin irritation or allergic reactions. These reactions can occur due to the harsh ingredients found in chemical products, such as relaxers, perms, or hair dyes, that may cause redness, itching, or swelling when they come into contact with the skin.

Individuals may have varying sensitivities to these chemicals, resulting in allergic responses that can affect the scalp or skin surrounding the hairline. It's important for professionals to conduct patch tests before applying a new product, as this can help identify any potential allergies and mitigate the risk of adverse reactions.

While issues like split ends, color fading, and heat damage are certainly concerns associated with hair treatments and styling, they do not pose the immediate health risks such as those associated with skin irritation or allergic responses. Hence, understanding the potential for irritation or allergic reaction is crucial for both cosmetologists and clients to ensure safe and effective hair care.
