You’ve seen the TikToks. You’ve heard the jokes. For a minute there, it felt like the entire internet decided that a hair with side part was the ultimate "millennial" crime, right up there with skinny jeans and using the laughing-crying emoji. Gen Z marched in with their middle parts and declared the side part officially deceased. But honestly? They were wrong. Trends are cyclical, but facial geometry is permanent.
The middle part is a harsh mistress. It demands perfect symmetry. If your nose is a little crooked or your eyes aren't perfectly level, a center part acts like a neon sign pointing it out. That's why the side part is making a massive, quiet comeback in 2026. It’s not just about nostalgia. It’s about balance.
The Science of Why a Hair With Side Part Actually Works
Most people don't realize there’s actual math behind why your hair looks better when it’s shifted two inches to the left. It’s about the "Golden Ratio." Our faces aren't symmetrical. Usually, one eye is slightly higher, or one side of the jaw is more defined. A hair with side part creates an asymmetrical frame that masks these little "imperfections" by drawing the eye across the face rather than straight down the middle.
Think about the "Strong Side." Look in the mirror. Close one eye, then the other. You’ll notice one side of your face likely looks a bit more "lifted." Styling your hair with a side part over the weaker side exposes the stronger side, instantly making you look more alert. It’s a cheap facelift. No needles required.
Celebrity hairstylist Chris Appleton, who works with Kim Kardashian and Jennifer Lopez, has often pivoted back to deep side parts for red carpets because they provide volume that a middle part simply cannot. When you flip hair against its natural growth pattern, the roots stand up. You get instant height. If you have fine hair, a middle part can make it look flat and, frankly, a bit sad. A side part gives it life.
Finding Your Natural Parting Line
Stop fighting your cowlicks. Your hair has a natural "preference" for where it wants to fall. If you force it into a middle part when your crown wants to go right, you’re going to spend your whole morning fighting frizz and flyaways.
To find your spot, brush all your hair back while it’s wet. Use your palm to gently push the hair forward toward your forehead. Watch where it naturally starts to split. That’s your sweet spot. Usually, it’s aligned with the outer corner of your eye or the highest point of your eyebrow arch.

Not every side part is created equal.

If you have a round face, a deep side part is your best friend. It creates a vertical line that elongates the face. A middle part tends to make round faces look wider because it emphasizes the cheeks. By shifting the weight of the hair to one side, you create an illusion of length.
Square faces need softness. If your jawline could cut glass, a sharp middle part might make you look a bit too "severe." A soft, slightly messy hair with side part breaks up the sharp angles of the jaw and forehead. It adds a bit of curve where there’s mostly straight lines.
Heart-shaped faces—think Reese Witherspoon—benefit from a side part because it narrows the appearance of a wide forehead while adding "weight" near the jawline. It balances the top-heavy nature of the face.
And if you have an oval face? Well, you win the genetic lottery. You can do whatever you want. But even then, a side part adds a level of sophistication that a middle part lacks. It feels more "intentional." It feels like you actually tried.
The "Millennial Side Part" vs. The Modern Side Part
We need to talk about the 2010s side part. You know the one. It was flat, it was glued down with hairspray, and it usually involved a very long, very straight bang that covered one eye like an emo kid from 2005.
That is not what we’re doing today.
The modern hair with side part is all about texture and movement. It’s not a straight line drawn with a ruler. It’s often a "deconstructed" part. Use your fingers instead of a comb. You want it to look like you just ran your hand through your hair and it happened to land there. This adds volume at the root without the "helmet head" effect.

- Pro Tip: Use a dry shampoo or a texture spray at the roots before flipping the hair over. This prevents the hair from falling flat against your scalp within twenty minutes of leaving the house.
- The "Zig-Zag": If you have visible thinning or just want a more bohemian vibe, a slightly messy, non-linear part hides the scalp better than a stark white line of skin.
Dealing With the "Growing Out" Phase
One reason people bail on the side part is the transition. If you’ve been rocking a middle part for three years, your hair has "memory." It’s going to keep trying to fall back into the center. It’s annoying. You’ll feel like you’re constantly tucking hair behind your ear.
Train it. When your hair is wet, part it where you want it and use a small duckbill clip to hold the roots in place while it dries. Do this for a week. Eventually, the follicles will give up the fight and stay put.
You also have to consider your haircut. A haircut designed for a middle part usually has symmetrical layers. If you suddenly flip that into a side part, one side is going to look significantly longer and heavier than the other. If you’re serious about the switch, tell your stylist. They need to "balance" the layers so the hair flows correctly when pushed to one side.
The Gender Neutrality of the Side Part
This isn't just a "women's hair" conversation. For men, the side part is the backbone of classic grooming. From the 1920s jazz era to the "Mad Men" look of the 60s, the side part has always signaled a level of professionalism.
But in 2026, we’re seeing a shift away from the "greased-back" executive look. Men are opting for longer, flowier side parts—think Timothée Chalamet or Dev Patel. It’s less about pomade and more about sea salt spray. It’s a look that says "I’m successful but I also might own a vineyard," rather than "I work 90 hours a week in a cubicle."
For guys with receding hairlines, a side part is a tactical maneuver. A middle part (or the dreaded "curtains") highlights a receding temple. A side part allows you to sweep the hair across the forehead, camouflaging the areas where the hair is thinning. It’s the oldest trick in the book because it works.
Debunking the "Side Parts Make You Look Old" Myth
The biggest argument against the hair with side part is that it’s "aging." This is a misunderstanding of how style works.

What makes someone look "old" isn't the part itself—it's the styling. If you're wearing a side part with a dated, crunchy perm or a 90s "pouf," then yes, it’s going to look dated. But a sleek, low side-parted bun? That’s timeless. It’s what you see on the runways for Chanel and Dior year after year.
The middle part is actually more punishing as we age. As we get older, our faces naturally lose volume and "sag" slightly (it happens to the best of us). A middle part creates a downward-pointing arrow right in the center of your face, which can emphasize drooping. A side part provides an upward lift. It’s a visual "pull" that counters gravity.
Actionable Steps to Perfect Your Part
If you're ready to jump back on the side-part bandwagon, don't just flip it and hope for the best.
First, get a tail comb. The thin handle is essential for precision, even if you’re going for a messy look. Start the part at the highest point of your eyebrow. This is the most universally flattering starting point.
Second, invest in a root lifting spray. If you have flat hair, a side part without volume looks like a wet curtain. Spray the roots while damp, blow-dry with a round brush pulling upward, and then flip the hair over.
Third, check the back. This is where most people fail. They part the front perfectly, but the back of the head is a mess of criss-crossed hair. Make sure your part either tapers off at the crown or continues in a clean line all the way back.
Finally, don't be afraid to switch sides. Most people have a "cowlick" on one side of their forehead. If you part against the cowlick, you get more volume. If you part with it, the hair will lay flatter. Decide which vibe you’re going for today.
The middle part era was a fun experiment in symmetry, but the side part is the reliable friend that never lets you down. It’s versatile, it’s corrective, and it’s finally being recognized again for the powerhouse styling tool it actually is.
Go to your mirror. Try the flip. See the difference. Sometimes, a two-inch shift is all it takes to completely change how you see yourself.
Your Next Steps for a Better Hair Day
- Analyze your face shape in a mirror today to see if your current part is highlighting your features or just hiding them.
- Experiment with depth. Try a "deep" side part (starting further toward the ear) for your next night out to see how it changes your jawline's appearance.
- Talk to your barber or stylist during your next appointment about "weight distribution." Ask them if your current cut supports a side part or if it needs a slight adjustment to lay correctly.
- Buy a high-quality dry shampoo. Volume is the secret ingredient that keeps a side part from looking like a "comb-over."
