Hair Dyes Can Cause Allergic Reactions.................

Skin and other allergic reactions pose the biggest risk to hair dye users. It's difficult to say how many hair dye users suffer from allergic reactions, as most do not seek medical attention. However, there are many cases where allergic reactions to hair dyes have been severe or even fatal.

Signs of a mild reaction may only be irritation of the upper eyelids or rims of the ears, but in more severe reactions, the whole head or body may be involved.

A severe form of allergic reaction is anaphylactic shock. When this occurs, the mouth and tongue swell and the airways constrict. Anaphylaxis can be rapidly fatal, and there have been isolated cases of hair dyes causing anaphylactic shock.

Skin reactions can occur on a person's first exposure to hair dye, or can suddenly occur in a person who has been using them long-term. A patch test before every dyeing is important to help detect skin allergies, but very time dye is applied to the skin, the immune system may become sensitized, increasing the risk of future allergic reaction.

Working as a hairstylist is associated with an increased risk of skin allergies. One review found that 17-80% of stylists suffered from allergic reactions on contact with hair dye
