 Although cutting the hair into a style is a simple and effective way to follow fashion and culture, there are more dramatic methods of hairstyling using chemical and plant extracts that give very different results. Hair colouring has long been a popular form of hairstyling. The colouring falls into four categories of temporary which washes out, semi permanent which usually lasts 6-8 weeks, deposit only/demi colouring and permanent. In colouring hair you have really an unlimited choice of colour especially in the case of permanent colours. Permanent colours use a developer and as alkalizing ingredient to alter the hair structure and penetrate the natural colour with the desired colour. Often peroxide is used to lighten hair and bring dark hair to a more blonde colour. Also popular today are highlights, which involve altering just certain sections of the hair with peroxide to give a textured multicolor effect.
Another choice of style is the permanent wave or Perm. This involves using chemicals to break the hairs natural structure and then set into curls. There is also an alternative for people with naturally curly hair. The use of a permanent relaxer has the same effect of breaking down the hair structure but instead of the formation of curls through rollers, the hair becomes straight. Another option that has become popular in recent years in western culture is Japanese hair straightening also known as thermal reconditioning. Instead of using relaxers to smooth out the hair, chemicals are applied and then the hair is ironed and blow dried straight piece by piece and has the benefit of causing less damage to the hair than relaxers do. |
