Instructions

Step 1: Shampoo. The charcoal pre-colour shampoo helps remove product build-up to prepare your hair for fabulous results.

Step 2: Rinse thoroughly, until the bubbles have left the building.

Step 3: Tip the colour into the rapid activator and shake it baby, shake it!

Step 4: Apply to towel-dried hair. No need to fully dry it off, this is a gel colour that does best on slightly damp hair.

Step 5: Wait. The rapid activator can shave 20 minutes off your colour’s processing time, depending on your desired colour result. So, which time is right for you?

For a natural blend:

Wait for 20 minutes if you want to blend grey hair rather than totally cover it. Twenty minutes is all you’ll need for natural looking beard or moustache coverage too.

For full coverage:

For maximum grey coverage, full colour integrity and the longest lasting colour wait between 30 and 40 minutes depending on how stroppy your grey hairs are.

Step 6. Rinse and condition. Add a bit of water to your colour to lather, then rinse until the water runs clear. Squeeze excess water out and lavish your locks with conditioner to help lock your colour in.
