Colour Responsible Policy

John & Associates follow a Colour Responsible Policy for the safety and peace of mind of our clients.


We use testing and screening to check suitability for the colouring products we provide.

AAT (Allergy Alert Test)
For your first AAT with John & Associates or if it is 6 months since your last AAT; 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. This needs to be left uncovered for 45 minutes, as that is the processing time of our colour. After 45 minutes the area can be washed off with lukewarm water.

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 contact a medical professional.


When you attend the salon we will observe the test site and ask you to complete a questionnaire.


Subsequent colour services may not require an AAT test subject to screening questions. We advise you to speak to your stylist about what is best for you. All our stylists have been trained to test and screen for suitability for colour services. We have vast experience in safe colouring – you can be sure we only use the best products and invest in the most up to date practices. We take your safety and our work seriously. When you visit John & Associates you can have peace of mind that we are taking the best care of you and your hair.


We thank you for your co-operation in our preliminary procedures before your service with us.



Skin Testing FAQ

How long does an AAT take and how much does it cost?
You will need an AAT appointment at least 48 hours before your colour appointment. It only takes 5 minutes in the salon and is a free test.

Why do I need a skintest?
Reactions to hair colour can be serious and even life threatening. There are strict guidelines from manufacturers, insurers, industry bodies and the MHRA around using hair colour. We endeavour to give you peace of mind so that you can safely enjoy your visits to the salon.

Why don't you test me every time?
We use screening to monitor the need for testing you before your service. If nothing has changed since your last test and we have a valid record (typically within the last 12 months) it will be OK to proceed with your service.

I have been colouring my hair for years, why do I need a test?
One of the triggers for sensitivity and reactions to hair colour is exposure over time, therefore it is important we keep monitoring for your safety. This is also the reason why we don’t test before every application; this would double your exposure to colour products. John & Associates are committed to your safety and use only the best products and methods for hair colouring.


Why don’t you accept a colourstart passport?
Colourstart is a patch test kit and not the actual product that we will apply to your hair. To be effective your AAT needs to be carried out with the product range that we use within our salon.
