Ultimate Color Sealer Liquid Layer - 6.2 oz

Lock in your salon-fresh vibrance instantly with the Wella Ultimate Color Sealer Liquid Layer, an advanced acidic post-color treatment designed for the most demanding color-treated hair. This innovative leave-in liquid works by rapidly rebalancing the hair's pH back to its natural acidic state (around 4.0), which effectively closes the hair cuticle and traps color pigments deep within the cortex. By sealing the cuticle structure immediately after an oxidative service, it prevents the dreaded "color washout" that typically occurs during the first few home washes, ensuring your signature shade remains rich and luminous for up to 8–10 weeks.

The magic of this "Liquid Layer" lies in its dual-action approach to scalp and hair health; while the acidic formula smooths the hair surface for mirror-like shine, it simultaneously provides instant relief to the scalp. Infused with skin-loving Allantoin and Aloe Barbadensis Leaf Juice, it soothes any post-color sensitivity, with 87% of consumers reporting improved scalp comfort after just one use. The inclusion of Wella’s patented Metal Purifier technology further detoxifies the hair by neutralizing copper and other metallic impurities found in tap water, preventing the chemical reactions that lead to brassiness and dullness over time.

This professional-grade treatment is engineered with a high-performance blend of Glycine, Squalane, and Pro-Vitamin B5 to reinforce the hair's internal structure and replenish lost moisture without weight. It creates a silky, anti-porosity shield that makes detangling effortless and protects against environmental stressors and free radical damage. Perfect for layering under other Ultimate Color products, this weightless mist transforms the texture of your hair from the first application, leaving it feeling revitalized, exceptionally smooth, and resilient enough to handle daily styling while maintaining its high-definition brilliance.

Instant Acidic PH Balance: This formula rapidly lowers the hair's pH to approximately 4.0, which is the optimal state for sealing the cuticle and locking in oxidative color molecules. By closing the hair's "door" immediately after treatment, it significantly reduces color fading and ensures a smooth, light-reflective surface.

Advanced Metal Detoxification: Featuring patented Metal Purifier technology, the sealer identifies and neutralizes copper and other metallic minerals in water that can cause unwanted color shifts. This proactive defense keeps your highlights bright and prevents your base color from turning dull or brassy between salon visits.

Immediate Scalp Comfort: Formulated with calming Allantoin and Aloe Vera, this liquid layer provides instant soothing relief to the scalp after chemical processing. Clinical tests show that 87% of users experience a noticeable increase in scalp comfort, making it a "must-have" for clients with sensitive skin.

Vibrancy for Up to 10 Weeks: When used as the primary post-color step, this sealer extends the life of your professional hair color for over two months. It acts as a permanent "glossy topcoat" that maintains the intensity of bold fashion shades and subtle tones alike.

Weightless Molecular Repair: Infused with Glycine and Squalane, the treatment penetrates the hair fiber to repair internal bonds and restore elasticity without any greasy residue. It instantly improves combability and reduces hair porosity, leaving your locks feeling revitalized and four times more resistant to breakage.
