In 2025, the definition of hair strength is getting a glow-up. It’s no longer just about breakage resistance—it’s about resilience, shine, vibrancy, and a healthy look and feel that lasts beyond your salon appointment. As beauty trends lean into individuality, lived-in color, and healthy hair texture, Redken Shades EQ and the Acidic Bonding Concentrate Leave-In Treatment are leading the charge.
Strong Hair Is Healthy Hair: The 2025 Trends
This year, hair trends are all about elevated natural beauty. Think soft dimension, blended tones, and high-gloss finishes that look effortless. From low-maintenance blondes and espresso brunettes to copper balayage, these color trends are taking center stage, and they all require one thing— healthy, conditioned hair that can hold color while looking and feeling its best.
Strength in 2025 isn’t just about managing damage—it’s about preventing it while enhancing your hair’s natural texture and shine. This is where Redken's Acidic Bonding Concentrate and Shades EQ come in.
Shades EQ: Color, Shine, & Care in One
Redken Shades EQ isn’t your average color product—it’s a demi-permanent hair gloss that’s ammonia-free and formulated with an acidic pH that helps maintain the integrity of your hair. Rather than penetrating deep into the hair’s cortex like traditional dyes, Shades EQ coats the cuticle, delivering vibrant tone and serious shine—without the long-term commitment or damage.
What Makes Shades EQ Different?
- Ammonia-free formula with an acidic pH that’s gentle on hair
- Fades gradually with no harsh line of demarcation
- Adds condition and shine with wheat amino acids
- Neutralizes brassiness and enhances natural tones
- Ideal for glossing, toning, lowlighting, and gray blending
- Shades EQ Bonder Inside tones and strengthens in one step
Whether you’re deepening your brunette, canceling brass in your blonde, or simply adding clear shine with no color change, Shades EQ is a stylist-favorite that delivers results in just 20 minutes. And when paired with the right care, that radiance lasts.
