Professional hair colour with ME+ technology

Wella Koleston Perfect 66/0 is a permanent cream colour formulated for professional use. The shade delivers intense dark blonde natural tones with pure, balanced results and natural depth. ME+ technology reduces free radical formation during processing for improved hair quality. The 60 ml tube mixes at a 1:1 ratio with developer.

Grey coverage and lift performance

The formula provides up to 100% grey coverage and achieves 5 levels of lift in a single application. Colour remains even and vibrant through repeated washing cycles without rapid fading. Balanced pigment distribution prevents patchiness on porous or previously coloured hair. Professional expertise is required to manage processing time and developer strength correctly.

Replaces standard permanent colour without ME+

Salons upgrading from older permanent ranges gain reduced free radical exposure for clients with sensitivities. The jump is worth it when clients demand maximum grey blending with minimal hair stress. Not suited for home users without professional training or for direct application without developer. Buyers seeking temporary or semi-permanent options should choose a different product type.

Questions about this item

Does the 60 ml tube need any extra equipment to mix and apply?

You need a developer and a non-metallic bowl and brush to mix at the 1:1 ratio before applying.

Can I use my existing developer with shade 66/0?

Yes, the shade works with standard oxidant developers mixed at 1:1 for up to 5 levels of lift.

Will the ME+ formula reduce irritation if I colour my hair every few weeks?

ME+ technology lowers free-radical formation, so repeated use carries less risk of new sensitisation.
