Achieve cool, sophisticated tones with this professional-grade colour correction system specially formulated to neutralise unwanted warmth whilst delivering exceptional shine and condition. The Ash Series from this celebrated collection features blue-violet undertones that effectively counteract brassiness and orange-yellow tones, making it the perfect solution for toning freshly lightened hair or refreshing faded cool shades. Advanced Melanin Gap Filler Technology works to reinject colour inside the hair fibre, filling gaps from lost melanin for a natural, dimensional finish that appears sophisticated rather than flat or artificial. The innovative ammonia-free formula operates on an acidic pH that respects your hair's natural structure, balancing and conditioning whilst closing the cuticles for healthier-looking results with three times more shine than untreated hair. Available in a comprehensive range of ash tones from Light Ash Brown (5.1) to Very Light Ash Blonde (9.1), plus sophisticated combinations like Ash Mocha (5.18, 7.18) and Ash Iridescent (6.12), this versatile colour collection allows for complete customisation whether you're neutralising yellow tones, creating an on-trend cool blonde, or seeking subtle ash brunette results with up to 70% grey coverage.

The premium gel-crème texture ensures easy mixing, seamless application and effortless rinsing, making it a pleasure to use for both professionals and at-home colourists seeking salon-quality results. L'Oreal Professionnel has formulated this specialised range with up to 92% natural origin ingredients, demonstrating their commitment to creating professional-quality products that are gentler on both hair and the environment without compromising performance. Each shade delivers true-to-tone colour that remains consistent from application to application, removing the guesswork often associated with toning and colour correction services. Particularly effective on blonde hair seeking to eliminate yellow tones (8.1, 9.1), or brunette shades requiring neutralisation of red-orange warmth (5.1, 6.1), these demi-permanent formulas provide the perfect solution for achieving cool, ashy results that look natural yet distinctly refined. The versatile shade selection includes standard ash tones alongside more complex combinations with mocha and iridescent reflects, offering unlimited creative potential for customised cool-toned results.

What truly distinguishes the Dia Color Demi Permanent Gloss system is its perfect balance between effective toning action and gentle hair care benefits that leave strands looking healthier than before colouring. Unlike harsh permanent dyes or toners that can leave hair feeling dry and damaged, this ammonia-free formula with shea butter and conditioning agents helps improve hair's overall condition while delivering precise colour results. The ash pigments are calibrated to provide effective neutralisation without creating overly flat or dull results, maintaining dimension and natural movement within the hair. Each 60ml tube provides sufficient product for a full application on medium-length hair when mixed with the recommended Dia Activateur (sold separately), with the colour gradually fading over approximately six weeks without harsh demarcation lines for easy maintenance. For clients struggling with persistent brassiness or warmth in their hair, these ash formulations represent a professional solution that addresses colour concerns while simultaneously enhancing shine and condition for a truly premium result. The carefully balanced cool tones work effectively on natural, coloured or highlighted hair, making this range extraordinarily versatile for all cool-toned colour aspirations from subtle ash enhancement to dramatic cool blonde transformation.

Whether you're a blonde battling unwanted yellow tones, a brunette seeking sophisticated cool dimension, or simply desire the current trend for ash-toned hair, this professional-grade system offers the perfect solution with gentle yet effective formulations. The 100% true-to-tone colour results eliminate the uncertainty often associated with toning services, delivering predictable neutralisation that can be precisely controlled through development time and shade selection. Particularly valuable for correcting colour issues or refreshing grown-out highlights, these ash formulations integrate seamlessly with existing colour while enhancing overall tone and dimension. The acidic technology not only ensures gentle processing but also creates exceptional shine that enhances the multidimensional appearance of the finished result, lending hair a healthy, polished appearance that appears naturally cool rather than artificially processed. With options ranging from subtle ash reflects to more intense neutralisation, this comprehensive collection addresses virtually every cool-toned colour goal with flexible, customisable solutions that can be used alone or intermixed for truly bespoke results. Combining professional neutralising performance with hair-enhancing conditioning benefits, this premium demi-permanent system represents the intelligent choice for achieving sophisticated cool tones without compromising on hair health or future styling options, delivering salon-worthy results with minimal commitment and maximum shine.
