My Hairdresser’s Hair Lightener is essentially a Bleach for the Hair. It is used to Lighten the Hair above 3 levels. It is generally used to achieve Blonde Hair from a Darker Hair Colour.
This could be for 2 reasons. 1. Your Colour has not lifted all the way. You need further lightening. 2. Don’t worry, this is normal! All you need to do is Tone. Try the My Hairdresser Toner Kit.
When using Hair Lightener, watch your Hair closely and leave the Hair Lightener on your Hair until you reach your desired Colour. Do not leave on for longer than 60 minutes.
