Sew In Hair Extensions - Jerry Curl Human Hair Bundles - Natural Black (1B)

A Coil Set to Last Rather Than Styled In
This spiral doesn't fall out by evening because the pattern lives in the strand's deepest bonds, the kind only a chemical straightener could pry apart to relax it flat. Day-to-day damp and friction can't reach that far, so the coil keeps its shape wash over wash instead of loosening into tired waves.

The Tight Jerry Spring
A jerry coils small and snug, tighter than a loose curl and springier under the hand, and that close wind is what packs so much volume into a single length. Give the spiral a squeeze and it bounces right back, which tells you the hair is fresh enough to hold its pattern through the whole install.

Off-Black Right From the Root
Sitting at #1B, this is the lived-in off-black your own coils grow into, and it never turns into the hard blue-black a box dye prints down. At the part that matters: the added spring picks up right where your leave-out stops, so your tracks settle into one head of hair with no telltale seam giving the bundle away.

Sews Flat, Lifts Off Clean
These wefts are built for a braid-and-sew, laid over your cornrows and stitched down so the weight rests on your braids and off your scalp. Come take-down, a single pass of the scissors along the top seam frees the row and your own coils sit undisturbed underneath.

A Coiled Edge That Won't Creep Loose
A curly weft wants to spring open at the cut, so the top seam is locked down twice to pin it shut. That double line of stitching is what keeps the row tight and shedding little after weeks of wear, right where you trimmed it to length.

Coils That Sip Their Moisture
A tight spiral bends the strand so hard that your scalp's own oil can't slide down to the ends, which is why a jerry runs dry rather than greasy. Work a moisturizing conditioner through after every wash and a leave-in between, and the pattern stays plump. There's a full routine in this guide to caring for curly extensions.

100 Grams the Coil Spreads Wide
That full 100 grams matters more on a spiral than on a flat sheet, because a coil fans out at every row. The weight has to reach across each track for the curls to read as one thick head rather than gapping between the rows, and a jerry bundle carries enough to do it.

Simple to Settle for the Night
With the curl set into the fiber and your own hair braided away beneath, bedtime is easy: a loose plait and a satin pillowcase. Satin cuts the drag that roughs up the strand's outer layer, and that's what keeps a curly install from waking up matted at the nape.

Takes a Clean Lift to Honey
It starts as deep as the natural black most heads already carry, and that even #1B depth is exactly what a colourist wants under the bleach. The outer layer is smooth and unbroken, so a jerry climbs to a #27 honey without the blotchy grab worn-out hair gives. The colour builds slowly through the strand, so you can call it done the moment the warmth looks right and the spring never leaves the coil.
