Hair Extensions - Jerry Curl 4x4 Transparent Lace Closure - Natural Black (1B)

A Square You Can Move the Part On
Four inches each way is a small panel, but it's still a square rather than a strip, so you get real say in the line. Drop it center, nudge it a touch off to one side, shift it with the day. A narrow lane forces you to live on one part; this compact square hands you a little room to change your mind while still capping only the crown.

The Smallest Patch of Lace to Disappear
Four inches square is the least mesh of any free-part base here, and the clear grade carries no colour, so it simply takes on the tone of the scalp showing through it. Less bare lace than any wider closure asks means the least to make vanish, which is why this one skips the tea-soak and concealer-matching stylists fight to get a base reading as their own part. That little window melts on its own.

Scales Facing One Way Keep It Smooth
Because the hair is root-turned, the outer scales all lie the same direction down every strand, root to tip. Processed hair gets those scales scrubbed off to stop it tangling; keeping them whole and lined up is exactly what lets a curly texture slide past itself instead of catching and matting through a full wear. On a jerry curl, which loves to knot, that's the difference between a clean install and a felted one.

A Core That Answers Heat Like Your Own
The inner body of a virgin strand, the part that makes up most of it, has never been chemically forced open, so its keratin still responds to heat the way it should. Press it under a flat iron or wrap it on a rod to wear it stretched for a day, then rinse, and the coil finds its way back on its own.

Curl Set at the Root and Kept There
This spiral is built into the strand's own inner bonds rather than wound onto a perm rod, which is why it keeps its bounce wash after wash where a rod-set curl loosens and drops over a long install. On a base this small the coil is doing your volume work, piling body over a footprint that barely registers.

Locked Down Fast, Least Left Out
This is the quickest base here to seat, simply because there's the least lace to stitch. A curved needle works a lock stitch every three-quarter inch through cotton-covered thread, anchoring each track without shrinking up or biting into the strands. And being the smallest cap in the line, it leaves the least of your own hair out underneath it.

Warms Up Evenly When You Want It To
Virgin 1B holds all its pigment, so it climbs the lift levels steadily rather than jumping. Carry the natural black to a warm honey #27 without the blotchy, banded result a pre-dyed strand gives, and on one compact square the closure takes that lift uniformly right alongside your bundles, no patch of lace-tint shifting on you.
