Questions about this item

Will the 6.66/6RR shade work on hair that still has old permanent dye in it?

The formula lightens up to 3 levels in 35 minutes and covers up to 100% of white hair, so it can lift through previous colour while depositing the dark deep red blonde tone.

How do I know the ODS2 ammonia-free formula processed correctly after the 35-minute development time?

Rinse until water runs clear; hair should feel softer than before colouring with a sublime shine and no ammonia odour, confirming full development.

Does the 60 g tube include the developer or must I buy it separately?

Only the 2.1 oz colour cream is in the box; a compatible oxidant developer must be purchased separately for the 1 to 1 mixing ratio.
