We strongly recommend you come in before each of your colour appointments for an allergy alert test. Whilst anyone can become allergic or sensitive to any colour product at any time, there is an increased risk of sensitivity or reactions with anyone who has tested positive for Covid-19 or even from just having any of the vaccines. Any change in your medical history can also affect your tolerance of hair colour.

If you are a New Guest to colour at Sally Adams or a returning guest who hasn’t visited us in the last 12 months, you will be required to have an allergy alert test at least 48 hours in advance of your appointment.

In addition, if you are a regular Sally Adams colour guest but you haven’t had a colour service with us since 1st February 2022, you will also be required to have a new Allergy Alert test as Aveda have changed their colour formulations & ingredients.

Please be aware that ahead of all colour applications you will be asked to confirm details of your allergy alert test or to sign a disclaimer to say that you have declined the test and chosen to have your service without it.

What is Allergy Alert Testing?

Allergy Alert Testing (previously known as Patch Testing) is a procedure used by our hair stylists, colour technicians and therapists before applying products that may cause an allergic reaction. It is a simple and safe way of identifying whether the product may cause an allergic reaction.

I thought Aveda only used natural ingredients. Why is it Necessary?

The Aveda colour products are about as natural as you can get! That’s one of the great things about the Aveda Colour system. It is kinder to the environment and kinder to your hair too. However a very small percentage of the ingredients are not naturally derived which is necessary to ensure any applications provide the fabulous results that they do. Our permanent colour is 97% naturally derived and semi-permanent 99%. Even so we strongly recommend an Allergy Alert Test - even if you have used the same product for many years, you can still develop an allergy over time.

(More information can be found on the Aveda website - Aveda.co.uk.)

What Does it Involve?

This is a complimentary procedure. The allergy alert test will usually be done 48 hours prior to an appointment. If the test produces a reaction on a client’s skin then the product must NOT be applied.

Prior to the allergy alert test we will ask you a few questions to ensure that it is safe for us to apply the product sample to your skin.

A small amount the product mixture is applied to the skin, usually behind the ear, and should not be washed off for the next 48 hours.

What are the Risks?

The chances of a reaction are very small. You should be particularly cautious if you have (or have previously had) a black henna tattoo. These temporary tattoos should be avoided because the paste often contains high levels of PPD, which can increase the risk of an allergic reaction to other hair/beauty treatments. If you develop itching, stinging or burning sensation or any signs of blistering however mild DO NOT proceed with an appointment. Contact your GP or attend an allergy clinic to investigate the reaction

What Should I Do if I Have a Reaction?

If you do have an allergic reaction to the patch test you should not under any circumstances proceed with an appointment until you have consulted a GP and clearly identified what caused your reaction.


Allergy Alert testing is an essential procedure to ensure the safe use of our products. Whilst it may be a little inconvenient to visit the salon 48 hours before your appointment it is essential to ensure your safety.
