You're standing in the hair care aisle or scrolling through Pinterest, and everything looks... fine. Just fine. But "fine" is boring. If you’ve got dark hair, you probably feel like your options are either "staying dark" or "going blonde." It’s a binary that honestly drives me crazy because it ignores the most versatile, low-maintenance middle ground in the history of salon chairs: brunette with auburn highlights.
It’s a vibe.
Auburn isn't just one color. It’s a spectrum. We’re talking about everything from a faint copper shimmer to deep, moody mahogany. When you weave those reddish-brown tones into a brunette base, you aren't just changing your hair color; you’re adding dimension that makes your hair look thicker than it actually is. Seriously. Flat color reflects light in a single plane, but a mix of warm tones creates shadows and highlights that trick the eye.
The Science of Why Warm Tones Work
Most people are terrified of "warmth." They hear the word and immediately think of brassy, orange hair that looks like a DIY disaster. But here’s the thing: natural hair almost always has warm undertones. When you fight that too hard with ash tones, the hair can end up looking dull or "inky." Adding brunette with auburn highlights actually works with your biology rather than against it.
According to color theory, red and copper tones sit across from blues and greens on the color wheel. If you have green or hazel eyes, auburn is basically a cheat code to make them pop. Even with brown eyes, the warmth in the hair brings out the amber flecks in the iris. It’s subtle, but it’s there.
I’ve seen stylists at high-end salons like Nine Zero One in LA use this specific technique to save over-processed hair. If you’ve gone too light and your hair feels fried, "filling" the hair with warm pigment—essentially creating that auburn base—is the only way to get it back to a healthy-looking brunette. It’s restorative.
Choosing Your Shade of Copper or Crimson
Don't just walk in and ask for "red." You'll regret it.

You need to know if you’re a Cinnamon or a Black Cherry. If your skin has cool undertones (think veins that look blue or purple), you want a cooler auburn. Think deep plum or burgundy mixed into your brown. If you’re warm-toned (veins look green, you tan easily), go for the fiery coppers and gingery browns.
It’s about the "melt."
A bad highlight job looks like stripes. You want a balayage approach. This is where the stylist hand-paints the auburn onto the brunette base, focusing on the mid-lengths and ends. It’s meant to look like you spent a month in the Mediterranean sun, not like you sat under a foil for three hours.
Maintenance Is the Catch (But It’s Manageable)
Red pigment molecules are huge. Like, physically larger than other color molecules. Because they’re so big, they don’t penetrate the hair shaft as deeply as brown or black pigments do. They sort of sit on the surface, which is why red is the first color to fade down the drain.
You’re gonna need a sulfate-free shampoo. Period.
I’m a big fan of the Pureology Hydrate line or anything by Kevin Murphy. If you use cheap drugstore stuff with heavy sulfates, that beautiful brunette with auburn highlights is going to look like muddy water in three weeks.

Also, cold water. I know, it sucks. Nobody wants a cold shower in January. But hot water opens the hair cuticle and lets those giant red molecules escape. Rinse with the coldest water you can stand. It seals the cuticle and keeps the shine locked in.
Why Celebs Keep Coming Back to It
Look at Dakota Johnson or even Rihanna during her more subdued phases. They often return to this specific mix. Why? Because it photographs better than flat black or platinum blonde. Under camera flashes, the auburn catches the light and creates a "halo" effect. It looks expensive.
In the industry, we call it "expensive brunette." It’s the opposite of the high-contrast "skunk stripe" trends we see on TikTok. It’s sophisticated. It says you have a 401k but you also know where the best dive bars are.
The Budget Reality
Let’s talk money.
Going blonde is an investment. You’re looking at $300+ every six to eight weeks, plus the cost of deep conditioning treatments because your hair is literally screaming for help.
Brunette with auburn highlights is the "quiet luxury" of hair. Since the base is your natural color (or close to it), the regrowth is seamless. You can go twelve weeks—sometimes even four months—between appointments if you get a good balayage. You’re essentially paying for the artistry once and then just coasting on it.

Just get a gloss.
Every six weeks, pop into the salon for a 20-minute gloss treatment. It’s usually around $50, and it deposits just enough pigment to refresh the auburn without the damage of a full color service. It’s the best-kept secret for keeping that "fresh out of the chair" look.
Stop Falling for the "Ash" Trap
Modern hair trends have been obsessed with "ashy" and "cool" for a decade. But honestly? Most people look washed out with ashy hair. It makes your skin look gray. Adding that touch of auburn is like putting on a permanent layer of blush. It brings "life" back to the face.
If you’re worried about it looking too "red," ask your stylist for "bronzed brunette." It’s the same concept but leans more toward a metallic brown than a primary red. It’s the gateway drug to full auburn.
Practical Steps for Your Next Salon Visit
Don't just show a picture. Explain the feeling you want.
- Ask for "internal dimension." This tells the stylist you want the color inside the hair, not just on the top layer.
- Bring three photos. One of what you love, one of what you "kinda" like, and one of what you absolutely hate. The "hate" photo is actually more helpful for a colorist.
- Discuss the "fade out." Ask them what the color will look like in six weeks. If they say "orange," find a new stylist. A good auburn should fade into a warm honey brown, not a rusted penny.
- Invest in a color-depositing conditioner. Brands like Overtone or Madison Reed make "espresso" or "copper" glosses you can use at home. Use it once a week to keep the vibrancy alive.
The biggest mistake is over-washing. Use dry shampoo. Embrace the oils. Your hair will thank you, and your color will stay vibrant long enough for people to actually notice it. This isn't a high-maintenance look unless you make it one. It’s the ultimate "lazy girl" hack for looking like you spent hours on your appearance when you actually just rolled out of bed and threw it in a claw clip.
The warmth of the auburn does all the heavy lifting for you. It reflects light, hides split ends better than blonde does, and grows out like a dream. If you’ve been on the fence, just do it. Hair grows back, but the confidence of a killer color shift is worth the risk.
Actionable Next Steps:
- Identify your skin's undertone by looking at your jewelry preference; if gold looks better, lean into copper-auburn; if silver, go for black cherry-auburn.
- Book a "consultation only" appointment before the actual dye job to ensure the stylist understands the "melt" technique.
- Purchase a microfiber hair towel to reduce friction and cuticle damage, which is the primary cause of premature color fading in warm-toned brunettes.
