Hair Extensions - Deep Wave 6x6 HD Lace Closure - Natural Black (1B)

A Deep S That Falls Full and Stays That Way
Deep wave is the tight, heavy S-pattern, and its whole character is bulk that holds. Wave after wave stacks dense down the strand, so the coil reads as texture that grew in rather than curl you set. That density is doing the real work on a closure: where a wider part shows more of the mesh below, this pattern falls thick over it and swallows the extra scalp, and it keeps that body across every wash instead of dropping the way an ironed-in curl does after one night.

The Coil Is What Buries the Six-Inch Join
A 6x6 opens thirty-six square inches at the crown, wider parting than a 5x5 allows without the near-frontal upkeep a 7x7 forces on you. On a square this open the deep wave earns its keep twice: it lets you set a part down the middle or angled off a corner, and its dense fall settles right over the six-inch seam where your wefts hand off, so the extra crown a wider closure bares is exactly what the pattern hides. Trim the border into the coil and the join reads as growth at talking distance and on camera.

HD Knots on the Sheerest Grade Tied
This is the finest mesh made, sheer enough that against a level-1 black the knots vanish with no dust of tint or foundation to help them along. A 6x6 only bares the crown your part runs through while a 7x7 opens a far sweeping field, so you start with that much less lace begging to be hidden at all, and the coil spilling over the edge shades the border for you.

Scales Kept the Way They Grew
Every cuticle here still points root to tip, all of it running one direction down the strand the way it sat on the head it came from. Strip that layer, which processing does, and matting and shedding start there; kept aligned, the coil slides past itself and stays smooth clear through a full sew-in. It's worth knowing what makes hair truly Remy before you spend.

Press It Bone-Straight, Wash the Wave Back
The deep wave lives in the strand's strongest internal links, and only a thio or hydroxide relaxer resets those. So iron the whole six-inch crown bone-straight for a single evening with a thermal shield on each pass; heat and water only ever bend the soft temporary bonds, so the wash after hands the full S right back across the square. Because this is genuine human hair, your wand and flat iron shape it the way they shape your own, where synthetic would singe.

A Level-1 Base With One Pigment to Move
Natural black sits at the very bottom of the colorist's ten-step scale, one pigment and nothing else pulling against a lift. Because this cuticle was never cracked by an earlier process, bleach reaches that pigment cleanly from root to tip, so a lift climbs without the muddy bands box colour throws. Take it toward honey blonde, or wear it black the day it lands. The 16 and 18 inch cuts are picked to end level with matching deep-wave bundles, so the wave carries down flush at the join instead of stacking short.
