What is the greatest risk associated with improper hair dye application?

The greatest risk associated with improper hair dye application is skin irritation or allergic reactions. Hair dyes contain a variety of chemicals, some of which can be harsh and lead to adverse skin reactions if not properly applied. The skin around the hairline and scalp is particularly sensitive, and improper application can cause chemical burns, redness, swelling, or itching. Allergies can also occur, where a person might develop a more severe response, such as anaphylaxis in extreme cases.

On the other hand, loss of hair volume is more of a consequence that can arise from damage caused by excessive or incorrect usage of dye rather than a direct risk of the application itself. Increased hair growth is unrelated to hair dye application and is influenced by factors such as genetics and overall health. Color fading happens naturally over time, especially with certain conditions of hair and environmental exposure, rather than being a risk associated directly with application techniques.
