In order to identify whether a client can have a colour service, a professional consultation needs to be conducted.

^{Disclaimer: This allergy alert test serves as an important precaution and has demonstrated reliability when executed under the specified conditions. However, it is important to be aware that even after conducting an allergy alert test, there remains a possibility of experiencing an allergic reaction when applying hair colour. This does not guarantee immunity from future allergic reactions. If you have any uncertainties, please consult a doctor.}

‍

Before proceeding with the test, ask your client:

‍

1. Is your client under 16 years of age?

2. Has your client had an allergic reaction to hair colourant products in the past?

3. Has your client had an allergic reaction to a temporary ‘black henna’ tattoo or permanent make-up?

4. Does your client have a rash on their face or a sensitive, irritated or damaged scalp?

‍

IF YES TO ANY OF THESE DO NOT CARRY OUT A COLOUR APPLICATION.

‍

‍

TESTING STEPS:

‍

Step 1: Prepare -

Mix in equal parts a small amount of product from Colour Sample (1) with Developer Sample (2) and create a thin layer covering an area measuring 2 by 2 cm onto the inside of the forearm.

‍

‍

‍

Step 2: Development

- Leave the product on for 45 minutes ensuring that you do not cover or touch the treated area. Avoid contact with clothing.

If you observe any itching, redness, or swelling on or around the test area, rinse the area immediately, discontinue use, and seek advice from a medical professional.

‍

‍

Step 3: Removal

- Rinse off the product from the test site and pat dry.

‍

‍

Step 4: Assessment

- Carefully examine the test area over the next 48 hours. If there is no reaction, you can proceed with the colour service.
