Wella Koleston Perfect ME+ 44/0 Permanent Hair Colour, 60 ml

Wella Koleston Perfect is a permanent cream colour for rich colour and shine. It suits both root touch-ups and full-head colouring from roots to ends; the appropriate colour and developer combination provides up to 100% grey coverage.

Mix the main range's shades with Welloxon Perfect at a 1:1 ratio. Select developer strength for darkening, same-depth colouring or lightening rather than using one concentration for every service.

What needs does this product address?

• Covering grey hair with permanent colour.
• Refreshing regrowth and matching it to the rest of the hair.
• Lasting changes to colour depth or tone with the selected shade.

How the formula works

The oxidative cream colour is designed for use with Welloxon Perfect. The main range's mixing ratio is 1:1. Use 6% developer for grey coverage; with the specified colour application method, 9% provides up to two levels of lift and 12% up to three. These methods differ from the Special Blondes 1:2 formula.

How to use

• For standard colouring, mix one part colour with one part suitable Welloxon Perfect developer (1:1).
• Apply the freshly prepared mixture immediately, touching up regrowth or colouring from roots to ends according to the chosen technique. Standard development time without added heat is 30–40 minutes.
• After development, add a little warm water, emulsify and rinse thoroughly. Shampoo with a product suitable for coloured hair and use the designated after-colour treatment.

For professional use. Before the service, follow the application and safety instructions on the packaging.

About the product

For grey root coverage, choose both the desired tone and a suitable natural shade and developer. Koleston Perfect's natural, brown and vibrant tonal families allow the formula to be tailored to the starting colour. The proportion of grey hair affects the shade mixing ratios.

For standard colouring, mix colour and Welloxon Perfect in equal parts. Use 4% developer for same-depth colouring or darkening when grey coverage is not required; select 6%, 9% or 12% for coverage or a defined level of lift. Standard development without heat is 30–40 minutes.

Refreshing previously coloured hair does not automatically require the same colour and developer as the roots. Welloxon Perfect Pastel 1.9% is used in designated colour-refreshing services, while Color Touch allows a separate toning service. After colouring, emulsify and rinse, then use an after-treatment for coloured hair.

Who is this product for?

For permanent root touch-ups or colouring from roots to ends, including grey coverage. Potential lift depends on the starting colour, chosen shade and developer strength.

Frequently asked questions

Do all Koleston Perfect shades use the same mixing ratio?

The main range uses 1:1. Special Blondes has a separate 1:2 method with a different development time.

Should the root mixture always be applied to the rest of the hair?

Choose a separate method for refreshing previously coloured hair according to fading and hair condition. The colour, developer and development time may differ from those used for the roots.
