Had a day out with Sophie today, we went to Tynemouth and did a Murder Hunt (like Cluedo meets Treasure Hunt), it’ll be a Fraggle report one day. So pleased to find this lady along the way, to help with my project. 🙂
Hair colouring is the practice of changing the hair colour. The main reasons for this are cosmetic: to cover gray hair, to change to a colour regarded as more fashionable or desirable, to restore the original hair colour after it has been discoloured by hairdressing processes or sun bleaching. The dyeing of hair is an ancient art that involves treatment of the hair with various chemical compounds. In ancient times, the dyes were obtained from plants.
The development of synthetic dyes for hair is traced to the 1860s discovery of the reactivity of para- phenylenediamine with air. Eugène Schueller, the founder of L’Oréal, is recognized for creating the first synthetic hair dye in 1907. In 1947 the German cosmetics firm Schwarzkopf launched the first home colour product, “Poly Color”. Hair dyeing is now a multibillion dollar industry that involves the use of both plant-derived and synthetic dyes.
