The best hair day of your life? You probably haven't had it yet-unless you've used this restorative, color-protective shampoo. Its thick, honey-like formula contains an extremely high dose of vitamin B5, which sinks moisture deep into every strand. Meanwhile, a Russian-inspired blend of chamomile, grape seed, rosemary, nettle, burdock, and sage infuses locks with a healthy gleam. The result: full, shiny, smooth tresses you've only dreamed of (until now).
