Questions about Colourstart

Colourstart is a ready-to-use patch test for finding out if you might be allergic to one of the ingredients, called PPD, found in most hair colorants

If the product you intend to use recommends that you test for allergy before using hair colour, you can use Colourstart instead. You should not use both the Allergy Alert Test and Colourstart.

To check if Colourstart is suitable for you to use please download the Patient Information Leaflet (PIL). Colourstart is not suitable for use by anyone under the age of 16.

Colourstart should only be used once if you are using the same hair colour product but may be repeated if you are switching to another product.

Colourstart is available from hair professionals in the UK.

If the instructions are followed carefully, it should not be possible to use more Colourstart than intended because it is a single use product. However, if you apply more than one patch or if anyone else applies the patch to their skin, remove as soon as possible and wash the area gently with water.

If you get any side effects, talk to your doctor or pharmacist. You can also report side effects directly via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.

Allergic reactions to hair colorant can cause itchy rashes, redness and blisters. In some cases, more severe reactions can occur.
