1. What Colourstart is and what it is used for
Colourstart is used to test for allergic contact dermatitis.
Contact dermatitis is a skin reaction caused by exposure to
foreign substances resulting in an allergic reaction.
Colourstart is a ready-to-use patch test for finding if your
allergic contact dermatitis is due to p-Phenylenediamine

Colourstart works by showing if you are allergic to the PPD
(allergen) on the patch. If a substance to which you are
allergic comes into contact with your skin it causes an inflammatory reaction called contact dermatitis. This substance
could be an ingredient in your hair dye. PPD is a well-known
allergen. If you are allergic to PPD, then the skin under that
patch will react to it, becoming red and inflamed. If you are
not allergic to PPD, the skin under it will not react.

The test consists of surgical tape with two patches. One of
the patches contains PPD and the other is a control.

2. Before you use Colourstart

ingredients of Colourstart
