Hair coloration is a popular fashion. Modern products can be divided into oxidative and nonoxidative types depending upon the chemistry that is used. The most common method is permanent or oxidative hair dyeing which requires three main components. The first is an easily oxidised electron rich aromatic amine such as p-phenylenediamine or p-aminophenol which is called a primary developer. The second component is a coupler such as m-phenylenediamine or m-aminophenol. The third component is an oxidant which is typically hydrogen peroxide mixed with aqueous ammonia. The hydrogen peroxide and aqueous ammonia mixture oxidise the primary developer which reacts with the coupler and colours the hair. Typically from 4-10 aromatic precursors are used. This process is based on AW Hofmanns 1863 discovery but it has three main disadvantages. It uses hydrogen peroxide which can be used to make explosives, ammonia is environmentally unfriendly and p-phenylenediamine is toxic along with the other aromatic amines and many by-products which form. A new method studied here avoids these three problems. In this method a suitable set of dyes will be designed, synthesised, purified and evaluated. As well as overcomeing the above disadvantages the dyes must adhere strongly to hair like the classical p-phenylenediamine derived dyes.
