You've probably spent years chasing the perfect sun-kissed glow. We all have. We've sat in those salon chairs for four hours at a time, foils stacked high, bleaching our strands into oblivion just to get that "expensive brunette" look. But here's the thing. Eventually, your hair starts looking flat. It looks muddy, or worse, just one solid, uninspired block of tan. That’s because you forgot about the shadows.
Lowlights on brown hair are actually the secret weapon of high-end colorists like Sharon Dorram or Tracy Cunningham. If you look at celebrities who always seem to have "perfect" hair—think Hailey Bieber or Dakota Johnson—they aren't just getting highlights. They’re getting depth painted back into their hair.
It's counterintuitive, right? Adding darker color to make your hair look better? But without the dark, the light has nothing to pop against. It's basic color theory.
The big mistake everyone makes with dark tones
Most people think lowlights are just "the opposite of highlights." Sorta, but not really. If you just slap some dark brown streaks into light brown hair, you end up looking like a zebra. It’s 2004 all over again, and nobody wants that.
Real dimension comes from choosing a shade that is only two, maybe three levels darker than your current base. If you’re a Level 6 light brown, you’re looking for a Level 4 or 5 for those lowlights. Go too dark, and it looks "inky." Go too warm on a cool base, and it looks orange in the sun. It’s a delicate balance.
Honestly, the biggest tragedy in modern hair color is the "over-foiled" look. You know the one. You keep going back for touch-ups, and the stylist keeps adding more blonde or light caramel. Suddenly, you aren't a brunette anymore. You’re just a washed-out blonde with dark roots. Lowlights on brown hair fix this by breaking up that solid mass of light color. It restores the "movement" that makes hair look healthy and thick.
Why your hair looks "thin" even if it isn't
Light reflects. Dark absorbs.
When your hair is all one light color, the light bounces off every single strand uniformly. This flattens the appearance of the hair. By strategically placing darker ribbons underneath the top layer and throughout the mid-lengths, you create the illusion of density. It’s like contouring for your face, but for your head.
I’ve seen clients with fine hair get a few well-placed mocha lowlights and suddenly, their ponytail looks twice as thick. It’s a total optical illusion. No extensions required.
Finding the right shade for your skin tone
We need to talk about undertones because this is where things go south. Fast.
If you have cool-toned skin—think blue veins and you look great in silver jewelry—your lowlights should be ash-based. Think mushroom brown, espresso, or cool mahogany. If you put a warm, gold-based lowlight on cool skin, it’s going to look "muddy" or "dirty." It’s just physics.
On the flip side, if you’re warm-toned (gold jewelry is your best friend), you want rich caramels, chocolates, and chestnuts. A cool, ashy lowlight on a warm brunette can actually make the skin look gray or tired.
- Cool Brunettes: Look for descriptors like "ash," "violet," or "iridescent."
- Warm Brunettes: Search for "golden," "honey," "copper," or "bronze."
- Neutral Brunettes: You can honestly play with both, but a "chocolate" shade is usually the safest bet.
The "Mushroom Brown" trend isn't for everyone
You've seen it on Pinterest. That gorgeous, earthy, almost-grayish brown. It’s beautiful. But listen: mushroom brown lowlights are high maintenance. Because they lack red undertones, they tend to fade quickly. Our hair naturally wants to be warm (thanks, melanin), so as soon as that ash toner starts to wash out, you’re left with a weird, mousy color.
If you go this route, you better have a blue or purple shampoo in your shower. You'll need it.
Placement matters more than the color itself
It’s not just about what color you use; it’s about where it goes.

A lot of stylists use a "weave" technique, but for lowlights on brown hair, a "slice" or a hand-painted balayage approach often looks more natural. You want the darker bits to live in the "recessive" areas—behind the ears, at the nape of the neck, and just under the crown.
This creates a "backlight" effect. When you walk, or when the wind hits your hair, these darker pieces peek through, making the lighter highlights on top look even more vibrant. It's the difference between a DIY box dye job and a $400 salon visit.
The "Money Piece" trap
Everyone wants the bright face-framing "money piece" right now. It's the TikTok trend that won't die. But if you have bright blonde ribbons right against your face and nothing but dark hair behind it, it looks harsh.
Lowlighting the section immediately behind the money piece creates a "frame for the frame." It makes the face-framing highlights look intentional rather than like an accident with a bottle of bleach.
Gloss vs. Permanent Color
Do not let a stylist put permanent color in for your lowlights unless you are 100% sure you want to stay dark for a long time. Permanent color opens the hair cuticle and deposits pigment deep inside. It’s a commitment.
Most expert colorists prefer a demi-permanent gloss or toner for lowlights. Why?
- Shine: Glosses are packed with conditioning agents. They make the hair look like glass.
- Fade: They fade gracefully over 6 to 8 weeks. This is actually a good thing. It means you aren't stuck with "stripes" as your hair grows out.
- Flexibility: If you decide you want to go lighter again in three months, it’s much easier to lift a demi-permanent color than a permanent one.
Permanent color is for gray coverage. If you aren't trying to hide grays, stick to the gloss. Your hair’s integrity will thank you.
Maintaining the dimension without breaking the bank
Let’s be real. Hair is expensive.
The beauty of lowlights on brown hair is that they are actually lower maintenance than highlights. Since they’re closer to your natural root color, the "grow-out" phase is almost invisible. You don't get that harsh line of demarcation at the three-week mark.
But you do have to deal with oxidation.
Air, water, and sun all conspire to turn your beautiful chocolate lowlights into a brassy mess. This is why a sulfate-free shampoo is non-negotiable. I’m not just saying that to sound like a commercial. Sulfates are literal detergents. They will strip that expensive demi-permanent gloss right off your hair in three washes.
A note on hard water
If you live in a city with hard water (looking at you, Los Angeles and London), the minerals in your shower are ruining your color. Calcium and magnesium buildup makes brown hair look dull and orange.
Get a shower filter. They're $30 on Amazon. It’ll save you $200 in "color correction" fees later.
Common misconceptions about going darker
"I’ll look too pale."
Actually, the right lowlight can add warmth back into your complexion. If you’re feeling washed out, it’s probably because your hair is too light and lacks contrast with your skin.
"It’ll look like a mistake."
Only if the sections are too thick. The key is "subtlety." You want people to say "Your hair looks so healthy," not "Did you dye your hair dark?"
"I can do it at home with a box of Revlon."
Please don't. Box dyes are formulated with high levels of ammonia and developer so they work on "everyone," but that usually means they’re too aggressive for most people. Plus, trying to weave your own lowlights in the back of your head using a bathroom mirror is a recipe for disaster.
Actionable steps for your next salon visit
If you’re ready to bring your brunette back to life, don't just ask for "lowlights." That’s too vague.
First, bring photos. But not just any photos—look for people who have a similar skin tone and eye color to yours. If you have brown eyes and olive skin, showing your stylist a photo of a blue-eyed, pale-skinned woman with ash-brown hair won't work out the way you think it will.
Second, use the right terminology. Tell them you want to "restore the secondary reflect" or "add depth to the interior." These are phrases that tell a stylist you know what you’re talking about.
Third, ask for a "tonal shift" rather than a "color change." You’re looking to enhance what you have, not start over from scratch.
Finally, prepare for the "fade-back." The first time you get lowlights over previously lightened hair, they will fade faster because the hair is porous. Plan for a "toner refresh" appointment about 4 weeks after your initial service. It’s usually a quick 30-minute
appointment and costs a fraction of a full color service, but it’ll lock that dimension in for the long haul.
Stop being afraid of the dark. The most beautiful, multi-dimensional brunettes aren't the ones with the most bleach—they’re the ones with the best shadows.
Next Steps for Long-Lasting Dimension:
- Audit your shower: Switch to a pH-balanced, sulfate-free shampoo specifically designed for color-treated hair to prevent the "brassiness" that often plagues brunettes.
- Book a "gloss only" session: If your hair feels flat but you aren't ready for a full foil, a 20-minute clear or tinted gloss can revive existing lowlights and add insane shine.
- Use a UV protectant: Brown pigment is particularly sensitive to sun exposure; a light hair oil with UV filters will keep those chocolate tones from turning orange during the summer months.
- Evaluate your lighting: Check your hair in natural daylight before deciding it's "too dark"—salon lighting is notoriously deceptive and often makes cool-toned lowlights look flatter than they actually are.
