Stop Buying the Wrong Lace: Are You Making This $200 Wig Mistake?
You Did Everything Right. So Why Does It Still Look Like a Wig?
You spent two hours bleaching the knots. You tinted the lace to match your skin. You laid it, melted it, tied it down, and waited.
From the front? It's giving scalp. Edges laid, hairline invisible, the whole thing looks like it grew there.
Then you turn your head slightly to the side, maybe catch your reflection in a car window or see a candid photo a friend posted, and the illusion completely shatters.
Somewhere behind your hairline, the part just... stops. The hair sits a little too thick, a little too lifted. It looks placed, not grown.
If that's happened to you, you're not bad at installs. You've just run into something most wig wearers never get told about.
Meet "The Crown Cutoff"
Stylists have a name for that moment: the spot where a wig stops looking like natural growth and starts looking bulky. We call it The Crown Cutoff.
Every lace wig has one. It's the invisible line where the lace ends and the wefts begin. In front of that line, hair is hand-tied into lace, one strand at a time, so it lies flat and moves like your own. Behind it, hair is sewn in rows, which adds lift and volume, and also adds tracks.

When your Crown Cutoff sits in the right place for how you style, nobody can tell. When it sits in the wrong place, every side angle gives you away.
So where is yours? That depends on one number most shoppers skim right past on the product page.
Why Your Favorite Styles Keep Exposing You
Look at the styles everyone is saving right now:
- Deep, dramatic side parts that sweep from way back on the head
- Snatched half-up, half-down looks that pull hair away from the crown
- Celebrity claw-clip updos that show the whole hairline and the hair behind it

Every one of these asks your part, or your pulled-back hair, to travel further back than you might think. And the moment it crosses the Crown Cutoff, the lace runs out. What's left is wefts, and wefts don't part cleanly. They show tracks.
That's why so many women can recreate these looks on a client's head in a salon video, but not on their own wig at home. It has nothing to do with styling skills. It has everything to do with two hidden inches of lace.
The Secret: The 4-Inch vs. 6-Inch Depth Rule
Here it is. That number on the product page, 13x4 or 13x6, is a measurement of your lace in inches.
- The 13 is the width: lace runs about 13 inches from ear to ear across your hairline. Both styles share this.
- The 4 or 6 is the depth: how far the lace reaches from your hairline back toward your crown.
That second number is your Crown Cutoff. A 13x4 frontal gives you about 4 inches of parting space before the wefts start. A 13x6 gives you about 6.
Two inches doesn't sound like much. But on your head, those extra 2 inches carry the lace from the top of your head all the way back to the crown. That's exactly where a deep side part ends, where a half-up style pulls hair away, and where a claw clip exposes everything underneath.
With a 13x6 HD Lace Frontal, your part can travel back as deep as you want and keep looking like scalp the whole way. With a standard 13x4, it hits the wefts sooner.
But here's the part nobody tells you either: that doesn't make the 13x4 the wrong choice. For a lot of women, it's the smarter one.
So Which One Do You Actually Need?
Now that you know why past wigs fell short, the fix is simple: match your lace depth to how you really wear your hair.
Choose the 13x4 if you live in middle parts and loose waves. A center part or a shallow side part never travels past 4 inches, so you'd be paying for lace you'll never use. The 13x4 still gives you a full ear-to-ear hairline, it's typically a little quicker to customize, and it saves you money. It's the undefeated budget pick for classic styles.
Choose the 13x6 if you switch your part, wear your hair up, or want realism from every angle. If you flip from middle to deep side part, love a half-up look, or want to throw it in a claw clip without a second thought, the extra 2 inches are what make that possible. It's the closest thing to free-parting hair.

Both options live in Ustar Hair's Swiss HD Lace Body Wave collection. Every unit is 100% human hair with thin Swiss HD lace, often called "skin-melt" or invisible lace, designed to blend into your skin once it's customized.
