How do I do a patch test?

Even if you have used Water Colour Gel hair dye before, and although it is an ammonia and PPD free hair dye, it is essential to patch test before every hair dye gel application.

Patch testing with Water Colour Gel is a simple 3-step process:

1. Mix Test Solution

Take a small pinch of Water Colour Gel powder and mix it with a drop of warm water. Be careful to reseal the cap securely on the remaining dye to keep it dry.

2. Apply Test

Clean a small area inside your elbow and apply the solution with a cotton bud. Allow it to dry and leave on for a minimum of 48 hours.

3. Monitor for Reactions

If irritation, redness, itching, swelling, or burning occurs, wash off immediately and do not use the product. If symptoms persist seek medical advice.
