A temporary black henna tattoo may increase your risk of having an allergic reaction when you colour your hair.
DO NOT use Colourstart if you have a temporary black henna tattoo. DO NOT use Colourstart if you have had any reaction to a temporary black henna tattoo in the past.

DO NOT perform the “Allergy Alert Test” as instructed on hair colorants in addition to using the Colourstart patch test.
This is because repeated exposure of the skin to PPD, whether through using hair colorant, performing the “Allergy Alert Test” or in using Colourstart, may cause sensitisation (development of allergy) in some individuals. For this reason, the Colourstart patch test should not be used more than once if you are using the same hair colour product, but may be repeated if you switch to a new hair colour product.

In rare instances, you may become allergic to the PPD present in the Colourstart patch test. This is also a risk with exposure to
hair colorants containing PPD. Any reaction which occurs at the site where the patch was applied, approximately 10 days later,
may be a sign of contact sensitisation. If this happens talk to your doctor or pharmacist and DO NOT use hair colorants.

Talk to your doctor or pharmacist if you require further advice regarding use of this product or in deciding if it is suitable for you.
