Wella\'s classic Welloxon Perfect developer range is now better than ever to create the most accurate hair colour possible. Available in a variety of volumes, the possibilities are now infinite as this new mixture has been specifically reformulated to achieve the best results on all hair types. This 6%/20 Volume Developer will provide 1-2 levels of lift, making it ideal for grey coverage and lightening without sacrificing the hair\'s moisture or shine. This also promises the most comfortable colouring experience possible as it creates an easy and fast mixing formula that works amazingly with adhesive foils. Another thing that makes this Welloxon Perfect formula better than past versions… It can now be used in conjunction with a larger variety of Wella colour ranges including Koleston Perfect, Blondor and Illumina Colour.
