I have worked alongside Naturawhite offering their one hour, non peroxide whitening treatment for about 2 years. I offer Naturawhite and their advanced Americanwhite treatment. The difference comes do how many treatments you will get on the day of your appointment, along with the strength of the whitening gel.
I can treat up to 2 clients at the same time which allows us to offer a reduced price treatment.
These treatments are both COSMETIC and fully legal in the UK.
