Colourstart Patch Test
There is no shipping charge on this product.
Colourstart is a clean and convenient way to screen for potential allergy to one of the chemicals, called para phenylenediamine (PPD), found in most hair colours. To reduce the risk of experiencing an allergic reaction to hair colour, some manufacturers recommend screening for allergy by using an Allergy Alert Test (AAT) on the skin.Colourstart can be used instead of the AAT to test for allergy to PPD.
Colourstart Passport is an online app that helps the user decide if Colourstart is suitable for them. Colourstart Passport can also store the user’s Colourstart test result for sharing with participating hair professionals, so making walk in colours possible.
This convenient method of patch testing means that you don’t have to come into the salon 48 hours prior to every colour service for a patch test. Once you’ve completed the Colourstart patch test and completed the questions in your passport & shared your results, all you need to do prior to each colour appointment is to simply log back in to your Colourstart passport and answer the questions again, sharing them each time with your salon. As long as there have been no changes, you are good to go.
