Hair colorants, or hair dyes as they are popularly known, occupy a large market today. They are used either to hide gray hair or to change the colour of the hair by individuals, either at home or at a hairdressing saloon. Colouring of hairs, eyebrows and eyelashes is not new and practiced from the earliest antiquity but in crude form. Avoid products that containing paraphenylenediamine (PPD), p - Aminophenol or Lawsone. The chemical have been reported associated with contact dermatitis (ranged from blister to full thickness chemical burn). This chemical also reported associated with cancer, however there is no sufficient data to support the relationship between hair dye use and cancer.
