How Many Bundles Do I Need For a Sew In?


"Gorgeous hair is the best revenge" - Unknown

Women have 99 problems, and we don't want your hair to be one.

If you ladies are anything like me, you don't play when it comes to your hair.

Well, I don't want you to ponder any longer on the quantity of hair you need. The right amount of bundles can make or break you're sew-in.

Fortunately, we all know how important your hair is to you at Private Label Extensions.

So you don't have to worry today! We're here to inform you of all your most common questions regarding how many bundles to use, weft, closures, sew-ins, and more.

Now let's jump straight into this!

Buying the Right Amount of Bundles for a Full Sew-In

The number one question that our clients ask is, "How many bundles do I need for a full sew in?"

Well, the answer varies based on the hairstyle, cut, length, and the size and shape of your head. I usually get three bundles for my primary sew-in, that's typically the magic number for your average sew in hair.

With three bundles anywhere from 12" - 20" your weave will be full, flowy, and glamorous. If your sew-in is starting with lengths over 22" you might want to consider four bundles.

A few things to factor are the size of your head (seriously), how full you would like your hair (deep wave styles generally have a lot of hair as an example), are you using a closure/frontal, and the overall type of hairstyle you are going for.

The basic sew-in usually consists of the full head braided up in the bee-hive. This or whatever your stylist suggests, with minimum hair, leave out.

However, some people prefer two bundles for a more natural look. Bobs are a trendy style, and they only consist of two bundles typically.


Comparison of Length and Weight for Various Bundles

Bundles from Private Label Extensions weigh​ ​about​ ​3.5​ ​oz or 100 grams.​

Although,​ ​all​ ​of​ ​our​ ​bundles weigh​ ​the​ ​same​ ​amount​ ​a​ ​10-inch​ ​bundle​ ​will​ ​always​ ​be​ ​fuller​ ​than​ ​an​ ​18​ ​inch if doing a sew-in.

Since the weight of the bundles of the hair is the same, you have to think of how the weight is proportioned.

A 10" bundle has a longer weft when compared to a 20" bundle. The weight of the hair in a 10" bundle is wide and long on a 20" bundle.

The reason you might need 5 bundles when using lengths in the 28" - 32" range is that the hair weight is going all the way down your back and not sewn around your head. You will need the additional bundles to give a full appearance when using really long lengths.

What Is A Frontal?

Let's get into these frontals and closures.

A frontal starts from one ear and ends at the other ear while covering the front of your entire hairline and is usually typically 13” long, and 4” wide and of silk or lace.

Frontals are available in a range of styles, hair types, and colors here at Private Label Extensions.

Say bye-bye, to the days when you only had three options:

  1. Leave out part of your hair to blend with your weave.
  2. The terrible invisible part that generally broke your hair off from glue.
  3. Perming parts of your hair and keeping the rest natural.

How many bundles will you need when also wearing a frontal?

Because the frontal will cover a large portion of your head you will generally only need 2 - 3 bundles depending on the style and length.

Working with Frontals and Closures

The closure and frontal era have come through for us ladies.

Frontals can also be used to cover up the loss of hair along the hairline.

Most women who wear lace frontals use them when they want to try an entirely different texture or color from their natural hair color.

When they want to protect their hair and edges that they would usually leave out in sewing in hair extensions. When wearing a closure, beings though it covers the whole front of your head, we would suggest you use a minimum of two bundles.

Obviously, you can add additional hair upon your request.

What Is a Closure?

Closures and frontals have similarities but are different based on size and coverage.

Closures are usually 4 x 4 inches and can sit either directly in the middle of the crown of your head. They can be altered moderately to the side to maintain a side-part style.

How many bundles do you need if adding a closure to your sew-in?

You will need to use a minimum of two bundles with your closure. But as I stated above, the longer the hair, the shorter the weft, so keep that in mind.

If you're trying to achieve any look other than a bob, we will always advise you to purchase three bundles with your closure. Always keep the length in mind!

What Is a Partial Sew-In?

If you're not interested in a full sew in with a closure or frontal, you can always get a partial sew-in.

Hair extensions can be a little bit pricey based on the style and how much hair is required.

Partial sew-ins have a more natural look to them, they're inexpensive, and they use about one and a half bundles of hair. However, we suggest you purchase two bundles of hair just to leave your hairstylist room for error.

Partial sew-ins leave sections of your natural hair out, usually, the entire crown of your head, and sometimes the back is also left out. The perks of partial sew-ins are they give a very natural look, and unlike other weaves, the styling is more flexible for natural looks.

How many bundles will you need for a partial sew-in?

Partial sew-in styles require less hair than a full sew-in hairstyle and will take a maximum of two bundles for standard lengths and three bundles if using longer lengths over 24".

How Many Bundles for the Kind of Hair Style/Hair You Want

There's nothing like a bomb sew-in, like in the words of Kenya Moore, “Hold on to your weaves ladies."

We have over twenty different types of hair at Private Label Extensions.

When getting a sew-in, it’s good to put careful thought into your hairstyle, hair length, hair type, and whether your sew-in is partial or full. The kind of hair you get will affect how many bundles you need to achieve your desired hairstyle.

Our Brazilian Straight hair is usually less dense than Brazilian Kinky Hair, so you’ll need more bundles for a brimful look.

Make sure you contemplate on the length you want as well.


How many bundles do I use to achieve my desired look?

Do you want a full and thick look, and then you will need three to four bundles.

If you want a thin, more natural, and tamed hairstyle, you will most likely only need 2 to 3 bundles. You will always use about 2-4 bundles.

Luckily, hair bundles are a great investment if taken care of they can last for many years. Take a look at our varieties of hair extensions we provide top quality, and we can assure you won't regret your purchase.
