MIX Wella Color Charm Toner with the matching Wella Color Charm 20 Vol Developer in a 1:2 ratio. This means you need double the amount of Wella Colour Charm 20 Vol Developer to Wella Color Charm Toner.
An easy way to measure this is to empty the toner into a bowl or application bottle first, then fill the bottle up with the developer twice and empty into your bowl or application bottle.
Your mixture should have a glue-like appearance.
APPLY Wella Color Charm Toner to well towel dried hair. As this is a liquid formula, if hair is too wet the toner may drip while it’s processing.
PROCESS the Wella Color Charm Toner for up to 30 minutes. It is very normal for your toner to turn a deep purple shade while processing. Scrape some of the toner off a strand to check often, until your desired shade is reached.
WASH the Wella Color Charm Toner from your hair well. Make sure the toner is well rinsed out, before applying a hydrating or protein treatment. To help the toner ‘stick’ better in your hair: rinse, treat and style as usual - and then wait approximately 3 days before washing the hair again. There is no need to shampoo after using the Wella Color Charm Toner.
