Superior gray coverage is one of the most effective ways to turn and reverse the clock on aging hair. Now, with 14 new shades added to the Joico Vero K-PAK Color Age Defy collection, gray coverage is just the beginning to revealing renewed hair! Vero K-PAK Color Age Defy is the first professional hair color that actually reverses the signs of aging. With the addition new shades in Natural Natural (NN+), Natural Ash (NA+), Natural Gold Copper (NGC+) and Brown Copper Red (BCR+) shade families, stylists can color with confidence - all shades provide 100% gray coverage. Gray is not the only characteristic of aging hair-strands also tend to become coarse, dry, dull, brittle and lifeless with time. Vero K-PAK Color Age Defy series defies the aging process, offering salon clients incredible coverage, unparalleled softness and manageability, dazzling shine and luster, and optimum condition. Shades are completely intermixable with all Joico Vero K-PAK Color shades, and feature a one-to-one mixing ratio.

A combination of time-released lipids, essential amino acids and bio-mimetic ceramides create superior condition and manageability with every color application. What's more, Vero K-PAK Color Age Defy contains Joico's award winning Quadramine Complex. This molecularly diverse keratin protein works from the inside out, offering unparalleled reconstruction, strength and long-lasting protection.
