Hair dye dia color 1 black 60ml L'Oréal

Semi-permanent hair dye without ammonia with alkaline technology, designed to deliver intense shine, colour refresh, and a natural tone-on-tone result. Its advanced formula helps achieve even grey coverage while improving the look and quality of the hair during the colouring process, leaving it more vibrant, soft, and luminous.

It provides up to 70% grey coverage and up to 1 level of gentle lift, while neutralising unwanted undertones for a cleaner and more balanced colour result. It is suitable for all hair types and allows easy customisation across cool, neutral, and warm tones for a natural, professional finish.
