Transform your hair with this gentle yet effective professional-grade colouring system that delivers exceptional results without the harshness of traditional permanent dyes. Dia Color Demi Permanent utilises advanced Melanin Gap Filler Technology to reinject colour inside the hair fibre, filling gaps from lost melanin for a natural, dimensional finish that lasts up to six weeks. The innovative ammonia-free formula works on an acidic pH that respects your hair's natural structure, balancing and conditioning while closing the cuticles for healthier-looking results with three times more shine than untreated hair. Available in a comprehensive range of natural shades from Clear to Very Light Blonde (9), this versatile colour collection allows for complete customisation whether you're toning freshly lightened hair, refreshing faded lengths, or seeking up to 70% grey coverage with minimal commitment. Each shade delivers true-to-tone colour that appears natural and luminous, without the flat, one-dimensional effect often associated with permanent colouring.
The convenient gel-crème texture ensures easy mixing, seamless application and effortless rinsing, making it a pleasure to use whether you're a professional or at-home colourist. L'Oreal Professionnel has formulated this premium 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. Natural Series shades can be used alone for classic results or intermixed to create bespoke colour combinations tailored to your precise requirements, offering unlimited creative potential. Particularly effective on sensitised, lightened or previously coloured hair, this demi-permanent formula provides the perfect solution for neutralising unwanted tones, refreshing colour between permanent applications, or adding a glossy finish to natural hair without significant commitment. The 60ml tube provides sufficient product for a full application on medium-length hair when mixed with the recommended Dia Activateur (sold separately), delivering salon-quality results that enhance both colour and condition simultaneously.
Whether you're new to hair colouring or a seasoned enthusiast seeking a gentler alternative to permanent dyes, this professional-grade system offers the perfect balance of performance and hair care. The ammonia-free formulation minimises scalp irritation and unpleasant odours commonly associated with traditional colouring products, making the application process significantly more comfortable. Each natural shade delivers predictable, consistent results that gradually fade over approximately six weeks without harsh demarcation lines, allowing for easy maintenance and flexibility to change your colour as desired. When used as a gloss treatment over natural or coloured hair, the acidic technology imparts exceptional shine that enhances the multidimensional appearance of your existing colour while improving the overall condition of your hair. The carefully calibrated natural shade range provides options for subtle enhancement or more noticeable transformation depending on your preference, with the versatility to address specific colour concerns such as brassy tones or fading. With its combination of gentle formulation, impressive colour results, conditioning benefits and flexible application options, this premium demi-permanent system represents the perfect solution for anyone seeking professional-quality colour enhancement without compromising on hair health or future styling options.
