Permanent Hair Colour Wella Koleston Perfect ME+ Pure Naturals 9/01 Blonde 60 ml

Wella Koleston Perfect ME+ Pure Naturals 9/01 Blonde 60 ml is a professional permanent hair colour formulated for even, long-lasting blonde results. Part of Wella's ME+ range, this 60 ml tube delivers concentrated pigment designed for full coverage on natural and previously coloured hair. The formula aims to provide natural depth and shine while offering reduced risk of developing a new allergy to hair colourants for people who are not already allergic. This shade is suitable for colour correction, root retouching and overall light blonde colouring in salon or at-home professional use.

Advantages

The ME+ technology in this Koleston Perfect formula provides stable, balanced colour with natural-looking shine and depth. The product offers reliable grey coverage and a straightforward 1:1 mixing ratio for consistent results. Compared with previous formulations, the ME+ range is designed to help reduce hair damage colour after colour by neutralising free radicals that can form during the colouring process. The 60 ml tube size is compatible with standard professional mixing volumes for targeted applications such as root touch-ups or full-head colour.

Suitable for

• Root retouching to restore even blonde tone
• Full-head colouring to achieve a light blonde shade
• Colour correction when moving to a lighter, natural blonde
• Covering up to 100% grey hair
• Use by professional stylists or trained users following salon protocols

When it may not be suitable

This product is not suitable for people with a known allergy to hair colourants. Although ME+ technology reduces the risk of developing a new allergy for those not already allergic, there remains a possibility of an allergic reaction. An allergy alert test should always be performed 48 hours before each colouration. The shade may not provide the same lift or tone on hair that has been heavily pre-lightened, bleached, or chemically treated; additional professional assessment may be required for such hair.

Usage recommendations

For predictable results, consult product instructions and a professional colourist. Use the 1:1 mixing ratio with the appropriate developer and keep to recommended development times. Test a small strand if changing from darker or heavily treated hair before full application.
