The #1 hair color brand in the USA, Colorsilk is co-developed with salon experts and formulated with Keratin and Silk Amino Acids to leave hair in better condition after coloring than before. One kit, complete at-home results.

Ammonia-Free Permanent Hair Color with 100% Gray Coverage

Revlon Colorsilk uses 3D Color Gel Technology™ to deliver natural-looking, multi-tonal color from root to tip. Unlike flat, one-dimensional color, 3D Color Gel mimics the way light interacts with natural hair — creating depth, dimension, and a radiant shine that looks like it came from a salon. Shade 37 Dark Golden Brown delivers a deep, rich brown with warm golden undertones that glow beautifully in natural light — the kind of color that looks like it was kissed by the sun rather than applied from a box.

The ammonia-free formula is gentler on hair and scalp than traditional permanent dyes. Keratin — the same protein that makes up your hair — is infused directly into the color formula to strengthen and smooth the hair shaft during the coloring process. Silk Amino Acids add moisture and shine, leaving hair feeling silky and healthy from the first wash after coloring.

Shade 37 Dark Golden Brown sits at the darker end of the golden brown spectrum, making it ideal for those with naturally dark brown hair who want to add warmth and golden dimension without going lighter. It provides complete gray coverage while delivering the rich, multi-tonal golden depth that makes this shade one of the most flattering warm browns in the Colorsilk range. Particularly beautiful on warm and olive skin tones.

Frequently Asked Questions

What is the difference between Revlon Colorsilk 37 Dark Golden Brown and 33 Dark Soft Brown?
Both shades are dark browns, but they differ in undertone. Shade 37 Dark Golden Brown has warm golden undertones that add visible warmth and a sun-kissed glow, particularly in natural light. Shade 33 Dark Soft Brown has neutral undertones that sit between warm and cool — it is more understated and universally flattering. If you want visible warmth and golden richness, choose 37. If you prefer a more natural, neutral dark brown, choose 33.

Will Revlon Colorsilk 37 Dark Golden Brown look orange or brassy on my hair?
Revlon Colorsilk’s 3D Color Gel Technology is designed to deliver balanced, multi-tonal color rather than flat or brassy results. Shade 37 Dark Golden Brown has warm golden undertones that are rich and natural-looking rather than orange. On very dark or previously colored hair, the golden tones may be subtle. To maintain color vibrancy and prevent brassiness over time, use a color-safe shampoo and conditioner and wash in cool water.

Does Revlon Colorsilk 37 Dark Golden Brown require a developer or mixing?
Yes. Revlon Colorsilk is a two-component system — the color gel and the developer are mixed together before application. Everything needed for a single application is included in the kit: color gel, developer, conditioner, and gloves. Follow the included instructions carefully for best results and even coverage from root to tip.
