Many people think that hairdressers perform miracles and expect their hair to turn from black or dark brown to platinum blonde in one sitting, and that is simply impossible. The truth is that Depending on the dark tone you have in your hair, it may take between two, three or four sessions To do it good. Although after the first or second session you may have an undesirable process, such as orange.
Before starting the lightening process of your hair at the hairdresser you will have to achieve the best possible condition for your hair, with which you will have to stop harsh chemicals from right now.
