EUFORA Ammonia-Free Hair Dye - 6.42/6CV Dark Copper Violet Blonde (3.4 oz) for Vibrant, Long-Lasting Color | Perfect for Salon-Quality At-Home Hair Coloring & Touch-Ups

Eufora color NO AMMONIA shades contain less than 1% MEA (Monoethanolamine) with permanent, long lasting 100% grey coverage. This series shines on its own and is calibrated to match level, tone and mixing formulations with the eufora color LOW AMMONIA Shades. The eufora exclusive Micro Molecular Technology in both LOW and NO AMMONIA shades allows for the low alkalizing agent levels in eufora color. This revolutionary technology allows for the creation of tiny pigment particles that easily pass through the small openings in the cuticle layer of the hair strand, depositing deeply into the cortex. The micro molecular pigment particles in eufora color are atomized in a vacuum environment, producing color pigment with 99.98% purity.
