Recommended time to leave the colour on the hair: is it important?
If you decide to leave the colour on your hair more or less than the recommended time, the end result cannot be guaranteed. The performances of the product can also be impacted.
Timing begins at the end of the application.
As a general rule, you must carefully follow the application instructions found on every Garnier hair colouring product.
This ensures the best possible result and guarantees your hair colouring product’s performances are optimized.
