You've seen them everywhere. On your Instagram feed, on that cool girl at the coffee shop, and definitely on every second celebrity hitting the red carpet lately. Medium long shaggy hairstyles aren't just a trend; they’re a full-blown lifestyle shift for people who are tired of high-maintenance blowouts. Honestly, it’s about time. For years, we were told hair had to be "done" to look good. But the shaggy look? It thrives on being a little bit undone. It’s messy. It’s gritty. It’s basically the cool older sister of the classic lob.
But here’s the thing. Most people walk into a salon, show a photo of Mick Jagger or 70s-era Debbie Harry, and walk out looking like they’ve got a literal mop on their head. Why? Because there is a massive misconception about what makes a shag actually work on hair that hits between the collarbone and the chest. It isn't just about hacking away at the ends with thinning shears. If your stylist does that, run. Seriously.
Why Your Current Hair Is Probably Bored
The "shag" is technically defined by heavy layering, usually focused around the crown, and often paired with some kind of fringe or curtain bang. When you apply this to medium-long lengths, you’re playing a dangerous game with "the shelf." You know the one. It’s when the top layer is too short and the bottom is too long, leaving a weird gap that looks like two different haircuts joined by a prayer.
A real expert knows that medium long shaggy hairstyles require "internal weight removal." This is a fancy way of saying they cut hair from the inside out so the layers collapse into each other rather than stacking like a staircase. Stylists like Sal Salcedo or Anh Co Tran have mastered this by using dry-cutting techniques. Dry cutting lets the hair live in its natural state during the process. You can see exactly where the wave sits. If you cut it wet, you’re basically guessing where those layers will land once they dry and shrink.
Most people think shags are only for people with natural waves. That’s a total myth. Even if your hair is as straight as a ruler, a shag can add the illusion of volume that no "volumizing" shampoo will ever give you. It’s all about the texture. By creating shorter pieces around the face and crown, you're forcing the hair to move. It stops being a heavy curtain and starts being a frame.
The Anatomy of the Modern Shag
Let’s break down what actually goes into this look. It’s not a one-size-fits-all situation.
First, you have the fringe. This is the heart of the shag. For medium-long lengths, a "bottleneck bang" is usually the move. It’s slim at the top and widens out around the eyes. It blends into the layers. If you go for a blunt bang with a shag, you end up looking like a Victorian doll who went through a hedge backwards. Not the vibe.
Then there’s the length. We're talking "medium long," which generally means hitting anywhere from the tops of the shoulders to the mid-back. This length is the "Goldilocks zone." It’s long enough to put in a ponytail when you’re at the gym, but short enough that the layers still have enough "bounce" to stay lifted. If the hair is too long, gravity takes over. The weight of the hair pulls the layers down, and suddenly your shag is just a messy long haircut.

Then we have surface layers. These are the bits you see on top. They need to be carved out. I’m talking about actual "carving" with a razor or point-cutting with sharp shears. This creates those "shards" of hair that catch the light and make people ask what products you use.
Texture and the Reality of Styling
Let's get real about the "effortless" part. No haircut is truly effortless unless you’re okay with looking like you just woke up from a 48-hour nap. But medium long shaggy hairstyles come close.
The secret weapon here is salt spray or dry texture spray. If you’re using a heavy silicone-based serum on a shag, you’re killing it. You’re weighing it down. You want grit. Think of the French girl aesthetic—it’s slightly matte, slightly "dirty" looking (even if it’s clean), and has a lot of air between the strands.
- Start with damp hair and apply a mousse. Yes, mousse. It’s back and it’s better than the crunchy stuff from the 90s.
- Roughly dry your hair with a diffuser. Don't touch it too much. Touching leads to frizz.
- Once it's 90% dry, hit the roots with some volume powder.
- Use a flat iron to create "S" waves, not curls. A curl is a circle; an "S" wave is just a bend.
If you have curly hair (type 3A or 3B), a shag is actually your best friend. It removes the "triangle hair" effect. By layering the top, you allow your curls to spring up, giving you height at the crown instead of all the volume being at the bottom. The "Rezo cut" or the "DeVa cut" philosophies often use shaggy layering principles to balance curly shapes.
Common Mistakes to Avoid
People often forget that face shape matters more than the Pinterest photo. If you have a long face, a very tall shag with a lot of volume on top can make your face look even longer. In that case, you want the volume at the sides, near the cheekbones. If you have a round face, you want those layers to start lower, maybe around the chin, to elongate the look.
Also, the "mullet" fear. It’s real. A shag is a cousin of the mullet. The difference is the transition. A mullet has a disconnected short front and long back. A shag is connected. If your stylist cuts the sides too short too fast, you're in mullet territory. Which is cool if that’s what you want! But if you wanted a bohemian, Stevie Nicks vibe, you’ll be disappointed.
- Don't over-thin: Too much thinning makes the ends look "ratty" or transparent. You want thick, chunky layers, not wispy ones.
- The Bang Gap: Ensure your bangs connect to the side layers. A gap there looks accidental and dated.
- Product Overload: Shags love movement. If your hair is stiff from hairspray, the "shag" loses its soul.
Maintenance: The Unspoken Truth
You might think a "messy" haircut means you don't have to visit the salon. Wrong. Because the layers are so specific, they can grow out into some weird shapes. To keep medium long shaggy hairstyles looking intentional, you need a trim every 8 to 10 weeks. This isn't about taking off length; it's about "re-pointing" the layers.

As the hair grows, the weight shifts downward. That volume you had at the crown? It’s now sitting at your ears. A quick "dusting" of the layers brings the shape back to life.
And let’s talk about the fringe. If you have bangs with your shag, you’ll likely need a bang trim every 3 weeks. Most salons offer this for free or a very small fee if you’re a regular client. Don’t try to do it yourself with kitchen scissors. You will regret it. I've seen it happen too many times.
How to Talk to Your Stylist
Don't just say "I want a shag." That word means a hundred different things to a hundred different people.
Instead, use specific language. Ask for "interior layering." Ask for "shattered ends." Tell them you want "movement without losing the perimeter weight." The perimeter is the very bottom edge of your hair. If that stays solid while the inside is layered, the haircut feels modern. If the perimeter is too thin, it feels like a 70s throwback (which is a choice, but usually not what people are after in 2026).
Bring photos, but bring photos of people who have your hair texture. If you have thin, fine hair, don't show a photo of a woman with a thick, curly mane. It’s physically impossible to recreate that volume without a gallon of hairspray and some clip-in extensions. Look for "fine hair shag" or "thick hair medium shag" specifically.
Actionable Steps for Your New Look
If you're ready to make the jump, here is how you actually execute this without the "haircut regret" that usually follows a big change.
Invest in a professional-grade dry texture spray. Brands like Oribe (Dry Texturizing Spray) or Amika (Un.Done) are industry standards for a reason. They provide the "grip" that keeps layers from laying flat. You spray it from the bottom up, shaking your hair out like you're at a rock concert.

Learn the "pinch and spray" technique. Take a small section of your layers, pinch the ends, and mist them with a light-hold spray. This defines the "shards" of the haircut so they don't just blend into one big blur of hair.
Switch to a microfiber towel. Regular towels roughen the cuticle too much. For a shag, you want the hair to look lived-in, but not damaged. Microfiber or even an old cotton T-shirt helps keep the layers clumped together naturally.
Adjust your sleep routine. A silk or satin pillowcase is non-negotiable. Because you have more layers, you have more "ends" exposed. Friction from a cotton pillowcase will lead to split ends much faster on a shaggy cut than on a blunt one.
Embrace the "Day 2" hair. Shags actually look better on the second day. The natural oils from your scalp add a bit of weight and shine that makes the layers look more cohesive. If it looks too oily, a bit of dry shampoo at the roots—not the ends—fixes it instantly.
The beauty of the medium long shag is its versatility. You can wear it "rocker chic" with a leather jacket, or you can soften it with a floral dress for a "boho" feel. It’s the ultimate "cool girl" shortcut. Just remember: it’s all in the layers. Keep them internal, keep them moving, and for heaven's sake, keep the thinning shears away from the very bottom.
Go find a stylist who understands the "carving" method. Your hair will thank you. No more boring, flat hair. Just movement, volume, and a little bit of that 70s rebellion that never truly goes out of style.
