Important: For any hair colouring services an Allergy Patch Test is required (free). It is the client's responsibility to book and visit the salon 48 hours before the actual treatment for the free patch test. The patch test involves putting a dab of hair dye behind the ear, leaving it there for two days, and looking for itching, burning, redness, or other reactions. If you experience any of these symptoms you must not continue with the treatment but seek medical advice. You should always tell your stylist before you begin any colour process if you had experienced of any allergies or recently have had a new tattoo done.
