You've probably seen it. That flat, one-dimensional "box dye" look that screams I did this in my bathroom at 11 PM. It’s not necessarily that the color is bad. It’s just that it’s too perfect. Real hair isn't one solid sheet of pigment. It’s a chaotic, beautiful mess of shadows and glints. This is exactly where lowlights in hair come into play. Most people run straight for highlights when they want a change, thinking more brightness is always the answer. Honestly? That’s how you end up looking like a Barbie doll—and not in the cool, Margot Robbie way.
Lowlights are the unsung heroes of the salon.
While highlights pull strands lighter than your base, lowlights do the heavy lifting by adding depth. They involve weaving darker tones throughout your hair to create contrast. Think of it like contouring for your face. You don't just use highlighter; you need the bronze and the shadow to make the cheekbones pop. Without that darkness, the light has nothing to bounce off of. It’s basic physics.
What are lowlights in hair and why should you care?
Basically, lowlights are strands of hair dyed two to three shades darker than your current color. They aren't meant to make you look like a brunette if you’re a blonde. They are meant to make your blonde look expensive. When a colorist like Tracey Cunningham—who handles hair for people like Khloe Kardashian—talks about "lived-in color," she’s usually talking about a strategic use of darker ribbons to mimic how hair naturally darkens in the under-layers where the sun doesn't reach.
If you’ve been over-bleaching for years, your hair eventually loses its "internal" shape. It becomes a wall of light.

Adding lowlights breaks that up. It gives the illusion of thickness. Because dark colors recede and light colors come forward, placing darker tones underneath or peppered through the mid-lengths makes the hair look denser than it actually is. It's a total optical illusion. Thin-haired girls, this is your best friend. Seriously.
The technical side: How the pros actually do it
Your stylist isn't just slapping dark paint on you. They use a few different techniques depending on the vibe you're going for.
Traditional foils are the standard. They section off tiny bits of hair, apply the darker tint, and wrap them up. This gives a very precise, controlled look. Then there’s "lowlighting with a tint back," which is more common if you’ve gone way too blonde and need to find your way back to sanity.
- Tonal Variation: You aren't just stuck with "brown." You can do caramel, mahogany, violet-based ash, or even deep copper.
- The Transition: Lowlights are the easiest way to grow out your natural roots without that harsh "skunk stripe" line.
- The Gloss Factor: Because lowlights are usually done with demi-permanent dyes (which are acidic), they often leave the hair shinier than high-lift bleach does.
According to George Papanikolas, a celebrity colorist for Matrix, the key is the "two-shade rule." If you go more than two shades darker than the base, it starts to look "stripey" or like a 2004 Kelly Clarkson video. Unless you’re going for a Y2K throwback, you want the transition to be buttery and soft. It’s about the whisper, not the shout.

Why your blonde looks "muddy" (and how to fix it)
Sometimes people get lowlights in hair and they hate it. They say it looks "dirty."
This usually happens because the stylist didn't account for underlying pigments. Hair has "warmth" inside it. If you put a cool, ashy lowlight over porous, bleached hair, it can sometimes pull green or grey. This is called "hollowing out." A pro knows they have to "fill" the hair first—basically putting back the red or gold that was stripped out during bleaching—before the dark color will stick and look rich.
It’s a chemistry experiment on your head.
If you’re worried about it looking too dark, ask for a "shadow root" instead of full-length lowlights. This keeps the darkness at the top, blending into your natural color, while keeping the ends bright. It’s the ultimate lazy-girl hack because you can go six months without a touch-up.

Maintenance: The part everyone ignores
Don't think that because it’s "darker" it won't fade. Red-based lowlights are notorious for washing out.
You’ve got to use sulfate-free shampoo. Period. No exceptions. Sulfates are basically dish soap for your hair; they’ll strip those beautiful lowlights out in three washes, leaving you back at that flat, over-bleached blonde. Use cool water when rinsing. I know, it sucks. But hot water opens the hair cuticle and lets the pigment molecules slide right out.
Also, get a gloss treatment between appointments. It’s like a top-coat for your hair. It seals everything in and keeps the lowlights from looking dull.
Actionable steps for your next salon visit
Don't just walk in and say "I want lowlights." That’s too vague.
- Bring photos of "depth," not just "darkness." Show your stylist pictures of hair that has movement. Point to the darker bits.
- Define your "tone." Do you want "honey and gold" or "mushroom and ash"? This matters more than how dark you go.
- Ask for demi-permanent. Most lowlights don't need permanent dye. Demi-permanent is gentler and fades more naturally, which avoids a harsh regrowth line.
- Inquire about "ribboning." This is a specific placement where the lowlights are thicker, creating a more dramatic, modern look rather than the "blended" look of the 90s.
- Check your lighting. Hair looks different in the salon chair than it does in the car. Look at your new color in natural sunlight before you leave.
Lowlights are ultimately about balance. If highlights are the stars of the show, lowlights are the stage, the lighting, and the background crew. They make the stars look better. Next time you feel like your hair is looking a bit "blah," don't reach for more bleach. Go darker. It’s the counterintuitive secret to the brightest, healthiest-looking hair you’ve ever had.
