The problem: Applying 20 Vol Developer on Natural Roots
You've applied your colour, and you love it, but your roots have ended up lighter and kinda brassy? This is called hot roots.
Hot roots happen when you apply a colour mixed with a 20 vol developer to your natural root area as this strength developer lifts the hair slightly.
This is more common with lighter shades and toners.
The solution: Use an Activating Creme or 10 Vol Developer on the root area.
You can apply your regular colour/toner mixed with 20 Vol Developer on the rest of your hair, but keep a little aside and mix with either an Activating Creme or 10 Vol Developer to use for your natural roots.
Both the Affinage Activating Creme and the 10 Vol Developer have been tested by Tint Department and work perfectly with the Wella Colour Charm Permanent Toners, Permanent Colours and Demi Permanent Colours.
The problem: Selecting The Wrong Base Colour For Your Needs
Knowing the base of the colour or toner you're looking at is the most important thing you need to know when picking a colour. Just picking based on the swatch, without knowing the base, could leave you very disappointed with the result.
The solution: Choose a colour or toner with the correct base colour for you.
Purple: Cancels out yellow
Blue: Cancels out orange
Green: Cancels out red
All of the Wella Colour Charm Toners and Colours stocked at Tint Department have the base colour listed. Just find your fave and check that the base colour will target your hair concern.
