If you’re looking for a softer, more natural way to wear red undertones, a cinnamon swirl balayage is the way to go. I paint these warm, spicy red tones onto a medium brown base to mimic how the sun would naturally lighten your hair.

4. Classic Auburn Glow

You can never go wrong with a classic auburn. This timeless color is the perfect harmony of brown and red, creating a shade that is both earthy and vibrant. It’s a universally flattering choice that exudes confidence and warmth.

5. Copper-Kissed Brunette

6. Mulled Wine Merlot

7. Spiced Chestnut

Spiced chestnut is the ultimate cozy color. It’s a warm, medium brown base with beautiful reddish and golden undertones that remind me of roasting chestnuts. It’s an inviting and easy-to-wear shade.

8. Black Cherry

For the bold at heart, black cherry is a showstopper. This color is an extremely dark brown, almost black, with a secret—a deep, cool-toned cherry tint that reveals itself in the light. It’s mysterious and incredibly high-fashion.

9. Terracotta Tones

12. Subtle Scarlet Ombré

An ombré is a fantastic way to experiment with red tones without committing to an all-over color. We keep your natural dark brown at the roots and gradually blend it into beautiful scarlet-tinged ends.

13. Russet Brown Waves

Want a high-impact look with minimal commitment? The money piece is your answer. We keep your gorgeous dark brown color and add a bold, face-framing highlight in a deep merlot red.

15. Toasted Almond & Cherry Babylights

Babylights are my secret weapon for creating the most natural-looking dimension. For this look, I weave superfine threads of cherry-red through a warm, toasted almond brown base.

16. Sun-Kissed Auburn Brunette

This look is all about recreating that perfect end-of-summer hair. We start with a natural brown base and strategically place warm auburn highlights where the sun would naturally hit, focusing on the layers around the face and the ends.

17. Garnet Glaze

Think of this less as a color and more as a top coat for your hair. A garnet glaze is a sheer, semi-permanent color applied over dark brown hair to give it a stunning, jewel-toned red reflect and incredible shine.

18. Fiery Brunette Bob

A sharp bob paired with fiery red undertones is a match made in heaven. The clean lines of the haircut really allow the vibrant color to take center stage.

19. Burnt Sienna Layers

This is a beautiful way to add warmth and dimension to long, layered hair. By concentrating the warm, earthy burnt sienna color on the ends of each layer, we create a gorgeous, flowing effect.

20. Cranberry Tinted Curls

For my curly girls, a subtle all-over tint can be transformative. A sheer cranberry red tint over dark brown curls adds a beautiful warm glow without overpowering your natural color.

21. Rich Chocolate and Burgundy Blend

This is the ultimate in decadent hair color. We melt tones of rich chocolate brown and deep, velvety burgundy together to create a seamless, multi-dimensional masterpiece.

Finding Your Perfect Red-Brown Hue

Well, there you have it! A deep dive into the wonderfully warm world of brown hair with red undertones. From the subtle glow of a Spiced Chestnut to the bold statement of a Cherry Cola Pop, there’s truly a shade for every personality and style. What I love most about these colors is their versatility—they can be soft and sun-kissed or deep and dramatic, but they always add a touch of warmth and sophistication that’s hard to beat.

For 2025, I’m seeing a huge trend towards these rich, dimensional brunette shades. People are moving away from one-note colors and embracing looks that have movement and complexity, and adding red undertones is the perfect way to achieve that. Think of stars like Zendaya or Isla Fisher, who have mastered the art of the radiant red-toned brunette. It’s all about finding that perfect balance that makes your skin tone glow and your eyes sparkle.

I hope this list has sparked some major inspiration for your next salon visit! Don’t be afraid to bring these photos to your stylist and have a real conversation about what you’re looking for.
