Common Shag Haircut Mistakes & How to Fix Them
If you struggle to keep a shag haircut from veering into mullet territory, you’re not alone. The balance between effortless texture and unwanted disconnection can be tricky. That’s why we hit up Rachel Williams (@rachelwstylist), Moroccanoil® Global Ambassador, ARC™ Scissors Artistic Team Member and expert in all things shags and dry detailing, for the mistakes she sees most (and how to fix them).
Mistake #1: Over-Layering the Crown
Leaving the back too long disconnects the shape, creating a mullet effect. This often happens when the crown is over-layered without blending.
The Solution:
Don’t take out too much weight and easily avoid over-layering: Rachel uses the ARC™ Scissors 30/2 Reversible Blender dry to carefully remove just enough weight. “They only remove 15 to 20 percent of the hair (depending on density) and I love this because for me, less is more,” she explains. This prevents collapse while keeping softness.

Mistake #2: Skipping the Face Frame First
A shag should flow from fringe to back. If the front isn’t mapped early, the shape disconnects.
The Solution:
Follow Rachel’s tried-and-true shag roadmap. “I always start with the face frame and fringe,” Rachel says. That way, top layers have something to connect to and the overall shape feels intentional.

For this voluminous curly shag, Rachel used Moroccanoil Root Boost Spray and finished with Moroccanoil Dry Texture Spray and Moroccanoil Luminous Medium Hold Hairspray.

Mistake #3: Not Customizing Shag Approach for Different Hair Types
Not every shag is cut the same, and sometimes, hair type determines if your client is suited for a shag. “I will never recommend a shag for thin hair because it is such a layered cut that it will take out too much weight and look like a mullet,” Rachel says.
The Solution:
If you’re cutting on finer hair, adjust your technique to customize with less layering—like Rachel demos below: “My client has fine hair, so I approached the way I cut a shag differently. She didn’t want to lose too much weight in her hair with too many layers!” Rachel shares.
Why you should consider cutting dry: “Notice how I did her cut on dry hair? That’s because I wanted to be able to cut while her hair is in her natural dry state in order to not take to much hair off, and to visually see her hair as I cut,” Rachel explains.
Mistake #4: Too Much Razor, Not Enough Strategy
Razors are excellent for creating movement, but excessive use without a plan can remove too much weight in the wrong places, leaving behind a choppy, harsh look.
The Solution:
Instead of using a razor, Rachel uses the ARC™ Scissors PHANTOM II 6″, to cut on the axis, mimicking razor-softness with more control.

Final Pro Tip: If You Have to Ask, It’s Probably a Mullet
Step back and assess the overall shape. Shag haircuts should have movement, softness and balance—not an abrupt contrast between short layers and long sections.
