Blondes may have more fun… but trust us, they have a lot more fun when their icy color stays sassy not brassy. & no shade on the color wheel helps maintain this cool more effectively than violet – the classic counterpoint that banishes oxidized yellowing; maintains the integrity of gray hair; & even turns into an instant at-the-sink toner following a blonde color service. That’s a whole lotta power for violet, don’t you think? Joico Color Endure violet Shampoo is the perfect choice for: blonde or gray hair that wants to stay calm, cool, & perfected.
