when many think of hairdressing they simply think if the cutting and dying of the hair. although hairdressing is so much more then this. even for just cutting someone hair you need great experience in how much to cut off and how to work the hiar around the face and the shape of it. to properly dye someones hair you cant just chuck some bleach on there and then wait for a couple hours to then add colour, you need to properly match the bleach with the hair colour your putting it on.
