Mix a small amount of BioKap Nutricolor Colouring Cream with an equal amount of Nutrifix Colour Developer lotion. As a container you can use a lid, a paper cup or a coffee cup.
Using a cotton bud, apply a small amount of the product behind the ear or in the crook of the elbow, enough to cover an area equal in size to about 1 cm square.
Repeat this two or three times, letting it dry in between. Close the colouring cream tube and the Nutrifix lotion bottle carefully, then wait 48 hours without washing, covering or touching the area.
If itching, redness or other skin abnormalities occur during this period, do not use the product and consult a dermatologist before using any other colouring product.
The patch test is a sensible precaution that can reduce, but not eliminate, the risk of an allergic reaction, even in the event of a negative result. If, after this period, no itching, redness or swelling is evident, apply the BioKap Nutricolor Dye product.
