Wella Koleston Perfect 12/1 Special Blonde Ash

This permanent hair colour delivers pure, balanced results with natural depth and shine. It is formulated with ME+ technology to reduce free radical formation and improve hair quality. The shade provides up to 100% grey coverage and achieves 5 levels of lift. It is intended for professional use on normal hair.

Professional permanent hair colour thermals noise

As a hair colour cream, this product does not generate heat, produce noise or draw electrical power during application. The formula works chemically at room temperature when mixed with developer at a 1:1 ratio. There are no thermal, acoustic or power considerations for the stylist or client.

Upgrade from standard permanent colour without ME+

This shade replaces traditional permanent dyes that lack ME+ technology for reduced sensitisation risk. The jump is worth it for colourists seeking pure blonde ash results with enhanced hair integrity and reliable grey coverage. It is not for home users without professional training or for clients needing temporary colour options.

Questions about this item

How do I mix the 12/1 shade with developer and what ratio mistake should I avoid?

Mix the colour cream with developer at a 1:1 ratio by volume. The common error is measuring by weight or guessing instead of using equal millilitres of each.

When will the 12/1 colour need to be reapplied on grey hair?

Regrowth at the roots typically requires a touch-up every four to six weeks because new growth shows the natural base again.

What limits how many levels of lift I can reach with this shade in one session?

The formula is rated for up to 5 levels of lift; pushing beyond that in a single application risks uneven tone and excessive damage.
