Leyton House Professional Couture Silk Permanent Hair Colour
Available Size: 100ml
Leyton House Professional Couture Silk Permanent Hair Colour is an advanced permanent colour system expertly formulated to simultaneously lift and deposit colour while maintaining the hair’s natural strength, condition and shine. Featuring innovative Simultaneous Lift & Deposit (SLD) technology, the formula uses high-performance micro-pigment colour molecules that penetrate the hair cortex faster than traditional colour, delivering rapid development, exceptional colour longevity and outstanding grey coverage.
The low-ammonia, pH-balanced formula is enriched with the exclusive Vegan Bond Complex, combining Hemp Seed Oil, Quinoa Oil, Erythorbic Acid and FillerPLEX to help protect, strengthen and condition the hair throughout the colouring process. The result is vibrant, long-lasting colour with incredible shine and up to 100% grey coverage.
