How Many Bundles For A Sew In?

If you've ever wondered how many bundles you will need for a sew-in, let's ease your worry about that in this article.

Like it or not, you can't achieve your desired look with the wrong number of sew-in hair bundles. So, from partial sew-ins to full-head sew-ins, the estimated number of bundles you need will be here.

Hair wefts come in a standardized 100 grams unless noted otherwise. This means you get about 3.5oz in every bundle.

You might have found yourself asking why you need extra bundles for lengthier hairstyles, well, it's because of the weight. Shorter hair extensions tend to have longer wefts and longer ones have shorter wefts.

That's why answering how many hair bundles you need for a sew-in is important to achieving what you want. But before giving specific numbers, some factors contribute to the number of bundles you will use. Let's see these factors below.

Factors that Influence How Many Bundles You Will Use

1. Length

From what we've stated earlier, clearly, a 30-inch bundle and a 20-inch bundle will have the same weight. Although one will have more wefts than the other, their weight remains equal. This means if you're choosing a longer hairstyle, you need more bundles than someone opting for a shorter hairstyle.

Our tip: Go for more than three bundles to have a fuller appearance if you want your hair longer than 22 inches.

2. Head Size

The average head is between 21 to 24 inches. With a measuring tape, measure yours. By measuring your head from ear to ear, you can discover the number of bundles you will use.

If the circumference is higher, you will need to get more bundles. But if it's smaller, two to three bundles should be enough.

3. Texture

You may be wondering how texture determines how many bundles you will use, it does and that's due to the density. Different hair textures (straight, curly, wavy) have different densities. This makes it compulsory to consider hair density before deciding how many bundles of sew-in you need.

Using a Curly Sew-In

The curly sew-in is a versatile hairstyle you can try. Whether you want to protect your natural hair or achieve a beautiful curly look, it's a good sew-in choice that won't disappoint.

For the installation, you will need between two to four bundles.

Since it naturally appears full and thick with few wefts, you don't have to use so much. For instance, two bundles of hair are enough if you want a short hairstyle of around 14 inches. If it's longer, you may need to add more bundles. That's because while it can give a full look, you want to avoid your braids showing in between.

Straight Sew-In Hair Extension Bundles

Straight sew-ins are another gorgeous option. However, they are less dense than curly ones and require more bundles for a voluminous look.

Going for a long style will need something extra. Regardless, three to four bundles should be enough for whatever style you want to make. This will be different if you choose to use frontals.

4. Frontals and Closures

Frontals and closures give you the option of slaying a chic hairstyle without damaging your tresses. These are a good option if you want to dye your bundles or want a different texture from your natural hair.

Because frontals cover the front area of your head, the number of bundles you'll need differs from sew-ins without frontals.

So, how many bundles for a sew-in with closure or frontals?

Generally, closures come in different sizes with the 4×4 being the most popular.

In most cases, two to four bundles are required for any hairstyle length with a closure. You can use two bundles for an 8-inch to 14-inch hairstyle, but if it's past 14”, you will need more bundles.

For frontals, the number of bundles is a little different. That's because it covers more of your hair than closures. At times, it can be from one ear to the other. And that calls for a different quantity of hair bundles.

Lace frontals are usually 13×4 inches, which means you don't need a lot of bundles like you would with a closure sew-in. Let's say you want a length between eight to 18 inches; then two bundles will be good enough. And for anything longer, three bundles will suffice.

Still, you must consider the other factors mentioned before purchasing your bundles.

Different Sew-In Methods

Now that we are familiar with the factors that may determine the number of hair bundles you may use. Let's check how many bundles are needed for the different sew-in methods.

1. Full Sew In

The full sew-in is also referred to as no leave-out sew-in. It involves braiding all your natural hair without leaving or adding them to the hair extensions.

A popular question everyone asks before getting a full sew-in is: how many bundles do they need for a full sew-in? But it won't be appropriate to determine how many you need without considering the factors above.

After considering them, we estimate three bundles upwards for a full sew-in. This also depends on the trims, style, etc. But three is a good number of hair bundles if your length is between 12 and 20 inches.

2. Braidless Sew-In

Another type of sew-in women love is the braidless sew-in. This method is different from the traditional sew-in, which is installed after braiding the natural hair. It uses microbeads instead, making it an innovative way of getting a ponytail style with your sew-in.

But when installing, how many hair bundles will you need?

The braidless sew-in method requires one to two bundles for the installation. However, this can vary based on diverse factors. So, take note.

3. Partial Sew-In

The partial sew-in is a popular choice among women. This allows you to leave out your hair at the front, crown, or edges for a natural and realistic look. Afterward, the hair extensions are blended with your hair for a gorgeous appearance.

So, as the name suggests, the partial sew-in is all about sewing your wefts to the few braids in your hair. The braids are often at the back of your head.

How Many Bundles of Hair Do You Need for a Partial Sew-In?

It can be difficult to decide on the go because there are many factors to consider first. This means the quantity of hair bundles will vary according to your style and length. But typically, you should use between two to three bundles for any style that surpasses 24 inches.

4. Vixen Sew-In

Here's another sew-in method that offers versatile styling options— the vixen sew-in. This method is unique as it allows you to wear your style in a ponytail, half up, half down, and different partings.

It is a new technique that sections your hair into four parts and sews the wefts to your hair.

But how many bundles do you think you need for a vixen sew-in?

Generally speaking, you may need three to five bundles for a vixen sew-in. But if you want it full, you will use up to those five bundles.

Frequently Asked Questions
