We require a skin test at least 48 hours prior to a colour appointment for new clients or clients who have not been to the salon in the last 6 months. There is no need to book this; you can pop into the salon whenever it is convenient. If you are unsure of when your last appointment was, please contact the salon at 02083182809, and we can check for you. Unfortunately, we do not offer a waiver form in place of a skin test.
