How Many Bundles Do I Need for a Sew In?

One of the most common questions when shopping for human hair is: How many bundles do I need for a sew in?

There isn't one number that works for every installation. A shorter style may require less hair than an extra long style, while someone who wants dramatic fullness may choose more hair than someone who prefers a natural density.

Your closure, frontal, texture and bundle length can also change how much hair you need.

Big Boss Bundles offers luxury human hair bundles in lengths from 10 inches through 32 inches, giving you options for everything from shorter everyday styles to long Boss Beauty transformations.

Quick Bundle Guide

The following is a general starting point rather than a rule. Your stylist, installation method and desired fullness can change the amount of hair needed.

Are 2 Bundles Enough for a Sew In?

Two bundles may be enough for some shorter styles, especially when a natural level of fullness is desired or when a closure or frontal is contributing additional hair to the finished look.

However, two bundles may not provide the fullness you want for longer installations.

Before purchasing only two bundles, consider your length and the amount of volume you expect from the finished style.

Are 3 Bundles Enough for a Full Sew In?

Three bundles are a popular starting point for many sew in installations.

For medium lengths, three bundles can often provide enough hair for a full appearance, depending on the texture, installation and density you want.

As the hair becomes longer, you may decide that a fourth bundle is necessary to maintain the fullness you prefer from the top of the style through the ends.

When Should You Consider 4 Bundles?

Four bundles may make sense when you're choosing longer lengths, want significant volume or are creating a style that requires more hair.

Customers shopping in the 22 to 32 inch range may want to consider the additional fullness that another bundle can provide.

If your goal is a dramatic, full look at 28, 30 or 32 inches, purchasing too little hair can leave you trying to stretch a small amount of hair across a much larger installation.

How Many Bundles Do I Need for 30 Inch Hair?

For a 30 inch sew in, many installations may use around four bundles, but the exact amount depends on your desired fullness, texture and whether you're incorporating a closure or frontal.

If you prefer very full hair, you may want more than the minimum amount.

Long hair makes density especially noticeable because you want the finished style to look full throughout the length rather than full only near the top.

How Many Bundles Do I Need With a Closure?

A closure covers a portion of the top of the installation and contributes hair to the finished style.

Because the closure is providing coverage and hair at the top, you may not need exactly the same amount of wefted hair you would use for a traditional leave out sew in.

The size of the closure and the length of the installation still matter.

Big Boss Bundles offers HD lace closures and frontals that can be paired with your bundle selection.

How Many Bundles Do I Need With a Frontal?

A frontal provides broader coverage across the front of the installation than a smaller closure.

Because the frontal itself contains hair and covers a larger area, it can reduce the amount of wefted hair needed in that portion of the installation.

However, the length and fullness you want through the back and ends still determine how many bundles make sense.

Does Hair Texture Affect How Many Bundles You Need?

Yes, texture can influence how full the finished style appears.

Curly and kinky curly textures may visually appear fuller because of the shape and volume of the curl pattern. Sleeker straight textures can create a different visual density.

That does not mean there is a fixed number of bundles required for every texture. It means texture should be considered along with length and your preferred fullness.

How Many Bundles for a Straight Sew In?

Straight hair creates a sleek silhouette, so the amount of hair used can be especially noticeable through the lower portion of a long style.

For medium lengths, three bundles may be a reasonable starting point. For longer straight styles, especially 24 inches and above, you may prefer three to four bundles or more depending on the density you want.

How Many Bundles for a Curly Sew In?

Curly hair can create substantial visual volume because of its curl pattern.

Some curly installations may achieve a full appearance with fewer bundles than an equally long straight style, but there is no universal rule.

Consider the specific curl pattern, length and how large or defined you want the finished style to appear.

Should All Your Bundles Be the Same Length?

They can be, but they do not have to be.

Using bundles of the same length can create a fuller appearance toward the ends.

Mixing lengths can create a layered effect. For example, a customer may combine 20, 22 and 24 inch bundles instead of using three 24 inch bundles.

Your choice depends on the finished shape and style you want.

What If I Want Extra Full Hair?

If your personal style is all about volume, plan for that before your appointment.

The minimum amount needed to complete an installation is not necessarily the amount needed to create the look you actually want.

If you love thick, dramatic hair, adding an additional bundle may make more sense than wishing you had purchased one after your installation has already started.

Bundle Length Matters

One of the biggest mistakes is assuming that three 12 inch bundles and three 30 inch bundles will create exactly the same density.

Longer hair distributes its weight across more length, which can mean less track width per bundle when bundle weights are similar.

That is why your bundle count may need to increase as your desired length increases.

Choose Your Hair Origin and Texture

Your bundle decision is not only about quantity. Hair origin, texture and the finished look are part of the experience too.

Big Boss Bundles offers luxury hair options including Cambodian, Burmese, Indian Raw, LAOS and Vietnamese hair in textures such as Straight, Body Wave, Deep Wave, Curly, Kinky Straight and Kinky Curly.

Ask Your Stylist Before Your Appointment

If a professional stylist will be installing your sew in, ask how much hair they recommend for the exact style you are requesting.

Your stylist can consider your head size, braid pattern, installation technique, closure or frontal and desired density.

Showing your stylist an inspiration photo can also make it easier to communicate the fullness and finished appearance you want.

So, How Many Bundles Should You Buy?

As a general starting point, shorter styles may use around two to three bundles, medium lengths often use around three bundles and longer styles may use three to four bundles or more.

But there is no single bundle count that works for everyone.

Your length, texture, closure or frontal, head size, installation method and desired fullness should all be considered.

When you're investing in quality human hair, the goal is not simply to buy a certain number of bundles. The goal is to have enough hair to create the Boss Beauty look you actually want.
