Colour Testing Policy

Evolve Hairdressing follow a Colour Responsible Policy for the safety and peace of mind of our guests.


We use testing and screening to check suitability for the colouring products we provide. You may choose either;

Colourstart Passport (MHRA APPROVED METHOD)

Register your interest in joining up to a Colour Passport by speaking to your Stylist. Once you have purchased your pack, you will receive an email invitation inviting you to sign up to the ColourStart Passport Service. Follow the instructions to create your profile; you will need information from your Colour Start Passport pack in order to complete your registration. Answer the screening questions and apply your Colourstart Patch following instructions in the video. Upload your results to your online passport. Share your results with your Evolve Hairdressing – (we are registered with Colourstart). Once you have created your passport and completed your first test, subsequent colour treatments require you to answer the screening questions – testing with a Colourstart test may not be necessary unless something changes. Your Colourstart Passport will confidentially store your records.

AAT (Allergy Alert Test)

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 forearm. 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 will require an AAT.. 

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 Evolver Hairdressing 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.

Frequently Asked Questions

How much is Colourstart and where do I buy it?
The Colourstart test is £15. You can buy it from Evolve Hairdressing. This can be posted out if more convenient for you. 

 You used to give me a Colourstart transfer for every colour service – what has changed?
Colourstart has been registered and approved by the MHRA (Medicines and Healthcare products Regulatory Agency) – subsequently we have to follow the guidelines as set out by the regulations. The test is different from the transfer test. It is supported by the Colourstart Passport. Your details are securely and confidentially held on your passport. Once you have tested with new Colourstart, subsequent colour services only require screening on your passport which could be just a couple of minutes. Potentially you could make an appointment and get your hair coloured on the same day.

Why is it Evolve Hairdressing’s preferred method for screening for colour allergies?
You are in control of your passport and therefor your testing and screening. It is confidential, we only get to see your result if you choose to share it with us. You can use your Colourstart passport for screening for any colour services in any salon. Example, if you have brow colouring service you can use the same test. If you are travelling and you need to use a different salon, you can share your passport result with any salon. You can get your service done with little notice, you do not have to wait 48 hours for a skin test.

I’ve been told Colourstart is not suitable for me – why is that?
If you are pregnant or have active dermatitis you cannot test with Colourstart. You should speak to a member of the team about an AAT (Allergy Alert Test) in the salon.


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 10 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 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 Evolve Hairdressing are committed to your safety and use only the best products and methods for hair colouring.
