Detailed Product Description

This product L'Oreal Casting Creme Gloss 300 Darkest Brown Semi Permanent Hair Dye is used for enhancing natural hair colour, adding long-lasting gloss, and blending away first greys with a rich, darkest brown shade. As the UK’s top semi-permanent glossing colour, it features an ammonia-free formula that prioritizes gentle colouring while delivering striking results. Infused with 10% Glycolic Gloss Complex, skincare’s gold standard ingredient, it seals hair cuticles to lock in colour and create a luminous, mirror-like shine that endures through up to 32 shampoos. Designed for hassle-free at-home use, it caters to first-time colourers and seasoned users alike, coming as a complete kit with everything needed for a professional-quality experience. The conditioning formula nourishes hair from within, leaving it not only vibrantly coloured but also up to 4x silkier and visibly healthier, without the harshness of ammonia. Whether preparing for a special occasion or simply refreshing your look, this darkest brown shade offers a rich, natural tone that complements a wide range of complexions, fading gradually over time for a seamless transition back to your natural colour.

Direction for Use

First, conduct an ALLERGY ALERT TEST 48 hours before each use, even if you have used hair colour products previously. Ensure your hair is damp and towel-dried (not unwashed dry hair) for optimal formula absorption. Put on the protective gloves provided in the kit. Mix the entire tube of Colorant Crème with the full bottle of Developer Crème and shake well to achieve a uniform blend. Apply the non-dripping mixture evenly all over the hair, spreading it thoroughly from roots to ends and massaging gently to ensure complete coverage. Leave the formula to develop for 20 minutes (up to 25 minutes for more intense colour). After development, rinse the hair thoroughly with warm water until the water runs clear. Apply the included Glossing Mask, leave it on briefly, then rinse again to reveal silky, glossy, and vibrantly coloured hair. Wait at least 2 weeks after a relaxer, perm, or straightening treatment before using this product. Follow the instruction leaflet for full details.
