A hair cut that sits right and is manageable for you to do at home?
Did you know that the hair has Hydrogen Bonds inside each strand of hair? When the hair is wet, the hydrogen bonds are broken, allowing hair to be formed into a new shape (Blow Dry or Blow Wave), as the hair dries they are re-formed in a new position thus holding the new shape.
Also hair is elastic, a hairdresser shampoo's your hair prior to cutting to thoroughly break the hydrogen bonds so that the hair stretches uniformly and then is cut in small methodical sections to enable precision and to build shape.
Because we stretch the hair and lift or elevate it whilst we work, we create graduation and weight, which cannot be seen when hair is wet and clumped together.
Without blow drying off the hair, then checking it for graduation or weight, where it should or shouldn't be, the haircut is only half done. The finish to a hair cut is achieved after the blow dry, as the stylist can check off any stray hairs from the perimiter, bulk in the layers, corners or weight where two different techniques meet and personalize your hair cut to your own personal head of hair. This is why to get the best result for your hair you should always go for a shampoo, cut and finish!
