Revlon ColorSilk 42 Medium Auburn is a vibrant yet balanced shade that blends medium brunette tones with rich copper and red reflects. It is designed for those who want a noticeable "glow" without moving into a deep burgundy or a bright fire-engine red. Formulated with Ammonia-Free technology, it provides a warm, autumnal finish that looks natural and high-shine.
Key Features & Benefits
Luminous Auburn Finish: Delivers a beautiful mix of red and gold undertones over a medium brown base, creating a "shimmering" effect in the sunlight.
Ammonia-Free Formula: Offers a gentle, odor-free application that respects the hair's structural integrity, making it ideal for those with sensitive scalps.
3D Color Gel Technology™: This signature Revlon tech ensures the color is multi-dimensional, providing natural-looking highlights and lowlights rather than a flat, artificial block of color.
Keratin & Silk Amino Acids: Infused with proteins that nourish and smooth the hair during the coloring process, often leaving it in better condition than before.
100% Gray Coverage: Specifically engineered to penetrate and saturate gray strands with warm, rich auburn pigments.
UV Defense: Built-in protection helps prevent the red molecules (which are prone to fading) from turning brassy or dull.
Shade Comparison: 31 vs. 42
