Colourstart consists of an adhesive patch that contains two small, separate squares. One square contains a small amount of PPD (this is the positive ‘+’ part), the other contains no PPD (this is the negative ‘-‘ part) and is used for comparison only.
The patch is applied to an easily visible part of the arm at least 5 days before an appointment for hair colour. The patch is left on for at least 48 hours (2 days) and then removed. 48 hrs (2 days) later, the arm can be inspected for any sign of a reaction.
If there is any sign of redness, itching or inflammation on the site of the patch, this is an indication that you may be allergic to PPD. If this happens you should not use hair colorant. If you are unsure about what to do, or if you have a severe reaction, you should seek the advice of a pharmacist or doctor. Please see the Patient Information Leaflet (PIL).
