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

A Six-Inch Square of Working Part
Six inches square gives you a whole hand-span of part to work, wider than a 5x5 opens up yet without the bare outer run a 7x7 leaves you to lay down. It's the middle of the range that reads generous but stays manageable, and it seals the crown right at the point your Spanish wave wefts finish, so the handoff never surfaces.

Every Scale Facing the Same Way
This is true Remy hair, with the outer scales still lying the direction they grew, every strand agreeing from root to tip. Sand that alignment away and matting starts within a wash or two. Kept in order like this, the waves glide past one another and stay tangle-free for weeks.

It Comes Through Both Stylist Checks
A good stylist runs two quick tests before she starts, a slide of thumb and finger up the strand to feel the surface, and a wet tug to read the bounce. Virgin hair like this passes both with a smooth outer layer and honest spring, which is exactly why the wave keeps its tension through a sew-in instead of going limp on you.

One Stitch Line, More Crown Sealed
Put your hair in flat braids and sew this one on, a curved needle carrying whichever knot you trust, a single lock, a double, or an overcast run. The six-inch base takes in more crown per stitch line than a 5x5 does, letting the part fall deeper toward a corner on the very same piece, edges braided away underneath with nothing loose to blend in.

Sheer Enough to Hold a Wide Part
A full six-inch square is a lot of mesh to keep believable, and HD is the one grade that carries it. Its knots ride on threads thin enough that the whole hand-span passes for scalp, so the part holds up across more width than a 5x5 gives without the exposed border a 7x7 asks you to bury. On a deep 1B there's no milky wash at the parting either.

Press the Square, Rinse the Wave Back
Nothing's permed into this hair, so the wave rides on the soft bonds that loosen under water and warmth and firm back up as it air-dries. That turns the part into its own styling surface. Press the full six-inch square flat for one event, let it dry, and the loose S returns across the crown. Keep a heat guard on for every hot-tool pass.

Room to Set the Part Where the Colour Lands Best
Nothing has ever forced this 1B's pigment open, so a lift comes up level and even all the way to honey blonde when you're matching bundles you've already coloured, with none of the patchy stretches pre-lifted hair leaves. Or keep it dark out of the pack, 16 inches or 18. The six-inch square then leaves you room to set the part wherever the new tone flatters you most.
