How Colourstart can help you

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.
