4B-4C Coil Pattern Fills a Texture Gap Most Brands Ignore
Here's the thing: tape-in extensions are overwhelmingly made in straight and wavy textures, which leaves tight-coily clients without options. This is an actual 4B-4C texture that matches that springy, z-shaped coil structure, so you get a blend that straight or wavy tape-ins just can't achieve without a ton of manipulation.
40 Pieces Distribute Weight Across 20 Sandwiches
Each sandwich holds a small, controlled section of your hair, spreading the total 100-gram load evenly across your scalp. Instead of concentrating weight at a few attachment points, you've got even distribution, and that's what reduces tension headaches and follicular stress.
Coily Texture Conceals the Tape Bond Beneath Curl Volume
The tight coils fan outward from the scalp in multiple directions, so they naturally bury each flat tape bond beneath layers of curl mass. Smoother textures just can't replicate that visual concealment without really careful layering. These do it automatically.
Tape Bonds Flex With the Coil Pattern
The adhesive tabs move with the natural spring and compression of 4B-4C curls rather than fighting against it. So the bond integrity holds through that stretch-and-return cycle tight coils produce during daily wear. They work with your texture, not against it.
Virgin Hair Responds to Standard Natural-Hair Products
Unprocessed cuticle and cortex absorb leave-in conditioners, curl creams, and oils at rates comparable to your natural hair. So your existing product routine works across both the tape-ins and your own strands. You don't need a separate regimen.
Coil Shape Is Permanently Set
The 4B-4C pattern lives in the strand's disulfide bond architecture, so the coils recover their original shape after stretching, pressing, or sleeping on them. No curling-tool intervention needed, because they just bounce right back.
Color-Liftable to Shade 27
Virgin cortex with intact melanin accepts lightener evenly to honey blonde, so you can add highlights or warm-tone accents on the extensions while your own hair stays completely untouched beneath the tape bonds.

4B-4C is the tightest coil pattern in this lineup. The strands form z-shaped bends rather than round spirals, and the coils compress so tightly against each other that from a distance, the hair reads as a dense cloud rather than individual curls. If your natural hair doesn't wrap around a pencil but instead kinks and bends at sharp angles, this is your texture.
What 4B-4C Coils Actually Do
Shrinkage is the biggest factor because 4B-4C hair shrinks 50-75% of its measured length. Twenty inches of this texture will hang around 5-10 inches when fully dry and coiled up, and that's not an exaggeration. So if you want length that shows, you need to order significantly longer than you think, or accept that the look is going to be about volume and density, not length.
And the volume is real. One pack of these at 100 grams creates more visible fullness than any other texture at the same weight. The coils stack and expand in every direction, so where straight tape-ins add length, these add crown. If you've been wanting that full afro silhouette or just more density in your wash-and-go, this is the texture that delivers it. For a deeper look at how extensions build fullness, our guide to hair extensions for volume covers the different approaches.
The Moisture Situation
4B-4C needs heavy moisture, but tape bonds don't like moisture near them. So the move is to keep your heavy products on mid-shaft and ends only, because that way the tape bonds stay dry and your coils stay fed. If you want a full breakdown of maintaining curly and coily textures in extensions, our curly hair extensions care guide walks through the details.
Before You Install
I know clarifying completely feels wrong for 4B-4C hair, but the tape needs clean, bare hair to bond. It's just for install day, and once the bonds are set you can go back to your full routine. Between appointments, keeping your natural hair moisturized underneath is just as important as caring for the extensions themselves, so our sew-in extensions guide has a section on moisturizing the hair beneath bonds that applies to any protective install.
Twenty sandwiches is enough for a full install on medium density hair. For high-density 4C hair, you might want a second pack, not because the first doesn't cover enough, but because matching the density of very thick natural hair with only one pack can leave the extensions looking thinner than your bio hair. On the other hand, if your natural hair is on the thinner side underneath those coils, our guide to extensions for thin hair explains which attachment methods to avoid and why single-sided tape might be a safer option for delicate strands.
