LumiShine YouthLock Permanent Creme Color - 7NN (7.00) - Natural Natural Medium Blonde / 2.5 oz. by Joico

Joico LumiShine YouthLock Permanent Creme Color - 7NN (7.00) - Natural Natural Medium Blonde. Revitalizing mature or gray hair isn't just about covering color—it's about restoring vitality, resilience, and brilliance. Joico's LumiShine YouthLock Permanent Creme Color infuses aging strands with youthful energy using a breakthrough formula powered by collagen. Designed to provide 100% gray coverage in 20 radiant shades, this advanced color solution delivers transformative results that go far beyond the surface. From the first application, hair regains its bounce, body, and signature LumiShine shine, while resistant grays are effortlessly blended with luminous, dimensional tones.

Powered by Collagen for Youthful-Looking Hair

At the heart of the YouthLock formula is collagen—celebrated in skincare for its ability to improve elasticity and moisture retention. Joico brings those same age-defying benefits to the world of professional hair color. With every treatment, this collagen-infused crème color helps soften coarse texture, improve manageability, and infuse dull strands with brilliance. Hair feels supple, hydrated, and more resilient, reflecting the vibrancy of younger days.

Instead of simply coating gray hair, YouthLock works in harmony with the hair's natural structure to restore softness, enhance movement, and maintain fullness. From lifeless, wiry strands to dry, brittle ends, this formula brings professional-grade care and radiant color together in one powerful service.

Complete Gray Coverage with Renewed Texture

One of the standout benefits of LumiShine YouthLock is its ability to completely cover gray, even in coarse, stubborn areas, without sacrificing shine or condition. Hair feels renewed—not just colored. The 1:1 mixing ratio with LumiShine Developer ensures a smooth, consistent application that glides easily through the hair and processes evenly from root to tip.

• 100% gray coverage in 20 professionally selected shades
• Mixes easily with LumiShine Developer for balanced, reliable results
• Ideal for brush or bottle application
• Processing time of 35–45 minutes ensures vibrant, even tone and coverage

Visible Transformation After Just One Service

Clients will notice a transformation in how their hair feels and behaves after a single treatment. Whether it's bounce in previously limp hair or a smoother texture where coarseness used to dominate, YouthLock helps stylists deliver outcomes that clients can feel immediately and see with every mirror glance. When used with Joico's K-PAK® Color Therapy™ Shampoo and Conditioner, the benefits are amplified even more, reducing breakage and restoring softness to chemically processed or aging strands.

• Infused with collagen to support elasticity, hydration, and fullness
• Improves bounce and body in fine or aging hair
• Smooths coarse, wiry strands for better control and styling flexibility
• Delivers a natural-looking finish with up to 2X the shine of untreated damaged hair
• Restores softness and resilience to brittle, dry hair types

Color with Confidence, Care, and Comfort

LumiShine YouthLock isn’t just about cosmetic color—it’s about care. The formulation respects the hair’s integrity throughout the coloring process, locking in hydration while helping prevent breakage. This makes it especially suited for mature clients whose hair may be more delicate, porous, or texture-challenged. The result? Hair that’s not only more vibrant but also easier to manage, style, and maintain between services.

Beyond the color itself, the user-friendly formula supports a smooth, stress-free application for stylists. Whether working with high-volume gray coverage or sensitive clients with texture challenges, this color line delivers on every front: from performance to finish to client satisfaction.
