Hair Dye And Its Dangerous Side Effects
Colouring the hair in the form of streaking to make it look stylish or to cover grey hairs, has become an important aspect of grooming for women and men alike, it is also quite routine, but what we don’t realise is, that regularly colouring the hair may be the cause of several health hazards.
In addition to using colouring agents. the hair dyes sometimes contain colourless substances such as aromatic amines or phenols. And in the presence of hydrogen peroxide, these substances go through a chemical reaction to become darker hair dyes.
Hair dyes also contain PPD (a chemical which is the main source of concern found in hair dyes) and ammoniated mercury metallic chemicals. If the hair dye does not contain PPD, it may have a higher concentration of lead, mercury and toxic metals. These have a bleaching action which enhances the colour of the hair. Peroxide breaks down melanin in the hair shaft to lighten the hair.
Hair dye may also contain some other chemical ingredients like coal tar, formaldehyde, paraben, phthalates, SLS, SLES, toluene, fragrance and hydroquinone.
The most common way to get exposed to the chemicals in hair dye is to dye the hair. Some chemicals in the hair dye can be absorbed in small amounts through the skin or inhaled from the fumes. People who work with hair dye as a part of their jobs such as hairdressers, stylist and barbers are likely to be exposed to these chemical ingredients.
