This isn't just a conditioner; it’s a professional-grade glow-up in a pouch. Designed specifically for those who want to keep their color vibrant and their shine levels "blinding," this refill pack delivers the same acidic-pH magic you love, with 75% less plastic than two of our standard bottles.

The "Science" of the Shine

How does it work? It’s all about the Acidic Shine Complex. Think of it like a top coat for your hair:

• Seal the Deal: The acidic formula (pH 3.5–4.5) mimics your hair's natural pH, sealing the cuticle tight to lock in color and moisture.
• Mirror-Like Finish: Infused with Vitamin E and Arginine, it smooths every strand for a finish so glossy you might see your reflection in it.
• Long-Term Love: Keeps your color looking salon-fresh for up to 32 washes, even when the "real world" tries to dull your vibe.

Why You’ll Obsess Over It:

• Eco-Chic: High-performance hair care that’s kinder to the planet.
• Mega Value: 500ml means fewer "out of stock" panics in the shower.
• Instant Detangling: Slippery, soft, and impossibly smooth—taps out tangles in seconds.
• The Fragrance: That signature Redken scent that makes your bathroom feel like a high-end spa.

How to Glow:

After shampooing with Acidic Color Gloss Shampoo, apply this liquid gold to mid-lengths and ends. Wait 1-3 minutes (use this time to practice your "shampoo commercial" hair flip), then rinse.

Pro Tip: For the ultimate glass-hair effect, use the full Acidic Color Gloss system. Your hair will thank you.
