This true-blue formula color-corrects on contact, instantly banishing those overly warm, orange tones that tend to turn up in graduated dark hair that’s been chemically lightened. Bonus: It preserves 89 percent of your precious hair color for nearly eight full weeks by bonding to hair fibers like a new best friend.
Perfect choice for naturally dark-brunette hair with salon highlights.
Massage into wet hair and allow the shampoo to absorb for three to five minutes, then rinse. Repeat the process two or three times per week, alternating with your regular shampoo.
