How Many Bundles Do You Need For A Sew-in?

If you are going to buy bundles but don’t know how many bundles you need for a sew-in, this blog will help you solve this problem.

This blog will explain the factors that influence the number of bundles you need for a sew-in clearly and systematically. Besides, you will also learn how many bundles you need for different sew-in styles.

At the end, there are also some frequently asked questions, which may be helpful to you.

1. Factors that influence how many bundles you need for a sew-in:

(1)Hair length

First of all, the hair length will have a great and essential influence on the number of bundles you need. The longer the hair you have, the more bundles you need in order to have a seamless and glorious appearance.

There is a reality that the standard weight of a hair weft is about 100 grams, which means longer hair extensions will have shorter wefts, and shorter extensions will have longer wefts.

Actually, the reason why hair length has an impact on the number of bundles is that the weight of a bundle is relatively fixed.

For example, a 16-inch bundle and an 18-inch bundle will have the same weight, while a 16-inch bundle has more wefts than the other. 

So if you are looking for a long hair appearance, you will need more bundles than those looking for a short hair appearance.

①Short hair

The range of short hair is from 8 inches to 14 inches. Normally, two bundles are enough for you to have a natural and seamless look, for the bundles are usually fuller and denser. 

Of course, you can also buy the third bundle according to your personal demands and individual preferences.

②Medium-length hair

The range of medium-length hair is from 16 inches to 20 inches. For medium-length hair, you can use three bundles to achieve a seamless and natural look.

If you want to add extra volume to your hair, you can also buy the fourth bundle.

③Long hair

The lengths of long hair are 22 inches or above. It requires three or four bundles to achieve a full and natural look.

What’s more, if you want a thicker and more voluminous appearance, you should also buy an extra bundle.

(2)Hair texture

As we all know, different hair textures have different densities, which will have an important and crucial effect on the number of bundles you need.

What’s more, hair texture will also influence the appearance of your hair, for different hair textures have various weaves and volumes.

①Straight hair 

If you have straight hair, you will need approximately three or four bundles to achieve a full and seamless look, for straight hair is normally sleek and has no volume.

②Wavy hair

If you have wavy hair, you will need about two or three bundles in order to have a glorious and appealing appearance.

The number of bundles you need is less than for straight hair because the wavy hair has more volume than the straight hair.

③Curly hair and kinky curly hair

Two or three bundles are enough for you to achieve a natural and seamless appearance for curly hair, and kinky curly hair is usually voluminous and dense.

(3)Head size

You should also take your head size into consideration when deciding how many bundles you need to buy.

That is to say, the larger the head size is, the more bundles are needed.

①Smaller head size

If you have a small head, you only need two bundles to achieve a full and glorious appearance, whether you have short hair or medium-length hair.

Of course, you can buy the third bundle in order to add more volumes according to your demands and preferences.

②Average head size 

Normally, the average head size for women is from 21 inches to 23 inches. If your head size is average, you will need three bundles to achieve a natural and seamless look.

③Larger head size

If you have a larger head size, you will need three or four bundles to achieve a natural and seamless look.

What’s more, if you have long and straight hair, you should buy an extra bundle to have a full and glorious appearance.

(4)Frontals and closures

A)Frontal:

The amount of bundles needed is smaller because frontals can cover a larger area. For shorter hair, two bundles are enough for you to have a natural and seamless appearance.

Medium-length hair will need three bundles, while longer hair will need three or four bundles to achieve a full and seamless look.

B)Closures:

If you choose closures, you will also need to buy fewer bundles. Shorter hair needs two bundles, and medium-length hair often requires three bundles in order to have an optimal and wanted look.

For longer hair, you need to buy three or four bundles to achieve a full and natural appearance.

If you have short hair, two bundles are enough for you.

If you have medium-length hair, you will need three bundles.

For long hair, you should buy three or four bundles to achieve a perfect and voluminous appearance.

Actually, there is no difference in numbers for you to choose frontals or closures.

(2)Partial sew-in

Partial sew-in style is also called a leave-out sew-in, which means you can leave out a section of your hair in order to make your hair blend with the hair extensions naturally and seamlessly.

What’s more, the sections of your hair left are usually the front, crown, and edges.
