If this is your first hair colour appointment with us. you must visit the salon at least 72 hours before your appointment in order for us to complete a patch test. This only takes 5 mins in the salon for us to do and you can visit any time during our opening hours, there is no need to book an appointment. We will then send you a follow-up email 24 hours later to confirm whether or not you have had any allergic reactions. If all is ok you can then attend your appointment as normal.
