All clients new to a colour service with us are required to have an AAT (patch test), or if it has been 6 months since your last colour or AAT. You will need to make an appointment to attend the salon at least 48 hours before your appointment. We will apply a small amount of colour formula to the inside of your elbow to leave for 48 hours. Should you experience any signs of irritation, reddening, swelling, inflammation or itching please contact us. If you develop symptoms that make you unwell, please seek medical advice. When you attend your colour appointment we will examine the patch test and ask you to complete a questionnaire.
