Hair Coloring or Bleaching is the process of turning your natural hair color in a different tone. You do it if you like to cover some gray or white hair, or if you want to be more fashionable or desirable.
The benefits of reaching the highest tone level are that you can change your hair color as often as you like and as long as it is applicable. You can go from Blonde to Platinum to Ash Brown, etc. in just 5 mins, you can match it with your suit, watch or shoes, and if you get bored with it, still it only takes 5 mins to go back to the way it is.
