Hair Bundles and Sew In Sets

Working out a sew-in usually comes down to two questions: how many bundles will actually cover the head at the length you want, and whether you're finishing the front with a closure or a frontal. Get those two things right and everything else, from texture to colour, is really about matching what you already have.

Straight and body wave bundle sets

Straight and body wave are the two textures most sew-ins are built on, because they sit closest to a natural blowout and are the easiest to match against a closure or frontal bought separately. A set built around three to four bundles gives enough length and thickness to fill a full head without needing extra one-off pieces later, and buying hair that's already pre-coloured saves the step of lightening virgin hair yourself.

Textured and curly bundles

Kinky straight and yaki textures suit installs meant to blend with natural relaxed or transitioning hair, since they read as a specific texture straight out of the packet rather than a straight weave. This matters if you're matching your own hairline or leave-out to a curl or coil pattern rather than starting from a blank, straight base.

Bundles with a frontal

A 13x4 frontal runs ear to ear, which lets you part the hair anywhere across the front and pull it back into a ponytail or updo without any leave-out. Full sets pair three or four bundles with a frontal for a complete head of length, while a single bundle sold alongside a frontal is really an add-on for a ponytail style rather than a whole install.

Colour-forward bundles

Balayage, piano highlights and pre-lightened blonde bundles skip the bleaching stage entirely, which spares the hair the extra processing of doing it yourself at home. A single bundle in a strong colour also works as a highlight piece mixed through a darker set rather than a full head of colour.

Single bundles for topping up

Not every install needs a brand new set. A single bundle is the right buy when you're matching an existing closure or frontal that's still in good shape, or just trying a texture before committing to three or four bundles of it.

Bundles with a closure

A closure is a small lace piece, usually four by four or five by five inches, sewn in to finish the parting instead of leaving your own hair out over it. It's the standard route for anyone who wants a natural-looking part without committing to a full frontal, and it asks for far less lace work to install cleanly.

How to choose

Bundle count: three bundles covers most shoulder to mid-back installs, four gives extra fullness for longer lengths.
Closure vs frontal: a closure covers the parting area, a frontal runs ear to ear and allows a shifted part or a ponytail.
Lace size: 4x4 sits close to the natural hairline, 5x5 and 13x4 give more room to style but ask for more careful lace melting.
Colour and texture: pre-coloured bundles skip a bleaching step, and matching curl pattern to your own hair keeps the blend seamless at the leave-out.

Questions people ask

How many bundles do I need for a full sew-in?

Three bundles is the standard for shoulder to mid-back lengths. Longer lengths or a fuller look generally call for four.

Do I need a closure or a frontal?

A closure is enough if you always part your hair in roughly the same place. A frontal is worth it if you want to change your part or wear the hair up.
