What it is:An illuminating, color-preserving serum that provides weightless definition.What it does:This revitalizing, silky smooth serum provides heat-styling protection, controls frizz and flyaways, polishes hair, and keeps all tones true. By locking color in and locking water out, you can keep even the hardest-to-keep hues as rich as the day of your service. Designed to treat dry or processed hair, Color Minded seals in shine and smooths the cuticle to make hair color glow, fights the horrid humidity, and adds healthy-looking luster and luminosity (just like a finishing coat). What else you need to know:Formulated with a new, proprietary two-polymer technology that covalently binds to and cross-links over color-treated hair, this color-preserving complex works to resurface the process-damaged cuticle and seal the hair to prevent color washout and fading. The color process opens the cuticle to deposit color into the hair shaft. If the cuticle is not sealed properly, water can enter and wash away new color as soon as the first shampoo (which is when the most color washout happens).
