Anti-Frizz No.4 Weekly Booster - 4 Pcs x 0.3 oz

Reclaim control over your morning routine with a targeted shot of high-performance humidity defense. The Milbon Signature Anti-Frizz No. 4 Weekly Booster is a professional-grade, intensive "top-up" treatment designed to extend the life of your salon results and keep stubborn flyaways at bay. Specifically engineered for frizz-prone hair, these convenient single-use vials deliver a concentrated dose of Milbon's proprietary Aqua Balancing technology. It works by evening out the moisture distribution within the hair shaft—essentially "filling in" the dry gaps that usually soak up atmospheric humidity—to ensure your style remains sleek, defined, and touchably soft from Monday to Sunday.

The magic lies in the formula's ability to weightlessly define waves and curls without the "crunch" or greasy residue of heavy oils. Infused with SSVR-Silk™, a powerful silk-based protein complex, this booster reinforces the hair’s internal integrity while smoothing the outer cuticle to a glass-like finish. It’s an essential insurance policy for anyone living in humid climates or struggling with naturally unruly textures. As you massage the creamy treatment into your mid-lengths and ends, it creates a moisture-locking shield that allows your hair to move naturally while maintaining total structural discipline. The experience is topped off with a sophisticated, refreshing fragrance of Lemon and Aloe, melting into soft notes of Muguet and Apple for a clean, botanical finish.

This isn't just a conditioner; it’s a strategic intervention for hair that refuses to behave. Because it is color-safe and ultra-gentle, it protects the vibrancy of your professional dye job while repairing the porosity that often leads to color fading. By using one vial per week in place of your usual conditioner, you provide your strands with the intensive nourishment they need to stay resilient against environmental stressors. It’s the ultimate "reset button" for your hair’s texture, providing that elusive salon-quality slip and shine in the comfort of your own shower. Authentic, effective, and expertly balanced, this booster ensures that your "good hair days" aren't just limited to the day you leave the stylist's chair.

Targeted Humidity Blocking Technology: Formulated with Aqua Balancing ingredients, this treatment optimizes internal moisture to prevent hair from swelling or frizzing in damp conditions. It provides a long-lasting, smooth finish that maintains your style’s integrity even in 80% humidity.

SSVR-Silk™ Protein Repair: This proprietary, silk-based complex penetrates deep into the hair fiber to fill in micro-gaps and restore structural strength. It repairs the internal damage that causes dullness, resulting in hair that looks healthier and more vibrant with every weekly application.

Weightless Definition for All Textures: Unlike heavy masks that can flatten fine hair, this booster provides a light, airy finish that enhances the natural bounce of waves and curls. It leaves no tacky buildup, ensuring your hair remains voluminous, manageable, and incredibly soft to the touch.

Color-Safe & UV Protective: Specifically designed to be gentle on treated hair, this formula locks in pigment while providing a protective layer against environmental oxidation. It helps prevent "wash-out" and sun damage, keeping your professional color looking rich and multidimensional for longer.

Convenient Professional Dosing: Packaged in four 0.3 oz vials, this system provides the exact amount of product needed for a weekly intensive treatment. This takes the guesswork out of your haircare routine, ensuring you receive a potent, salon-grade concentration of active ingredients every single time.
