How Many Bundles Do I Need For A Full Sew In: The Ultimate Guide

Have you ever been shopping at the store or online and always get stuck when you have to choose the number of bundles to purchase for your sew in? We’ve all been there. There is no real answer. It depends on the hairstyle you are trying to achieve. You have to take into consideration the cut, length, size and shape of your head. The average number that customers usually buy is three to four for their primary sew in. 3 bundles are sufficient for your hair to look natural and voluminous.

Why Choose Hair Bundles To Make A Full Head Sew In?

Bundles or Packs? The main difference is its quality.

This is the other headache you must have. Having to choose between packs and bundles when getting a sew-in.

Do you know how different these two are? Trust me you can never ponder over which to choose ever again, the choice will always be automatic after knowing the differences.

  • Bundle hair: High quality, lasts longer, feels and looks like natural hair, can be washed, colored, permed and even blow dried. I mean there is no competition to this.
  • Packed hair: Low quality, does not last long, cannot be washed because it will tangle (it tangles on its own anyway), cannot be done anything close to what you can do to natural hair.

There is no comparison really when it comes to the two. Choosing hair bundles is the best option for you to achieve the hair style that you wish.

Criteria to Take Into Consideration:

Size of your head

In the US, The average size of a woman’s head is 22.5 inches. So, measure your head using your measuring tape by wrapping it around your head. Then, if it is more or less than the average size you would adjust the number of bundles. The bigger your head the more bundles you need and vice versa.

Hair Length

The greater the number of inches you want, you will need more bundles. Why? Human Hair tends to thin out towards the tip. Hence, using more bundles will allow your hair to look fuller.

Hair texture

Curly and straight human hair are of different densities. Curly hair is naturally fuller hence you may need fewer bundles. With KN curly hair, you can get away with less bundles since the hair density is naturally going to be to fuller. We recommend 2-3 bundles for a naturally full look. If you wear straight human hair, then you will need more bundles to create the full look. Although KN straight hair is still full from root to tip, you might need more bundles to create a super full look. We recommend 3-4 bundles depending on the length.

Hair Volume

More volume, more bundles. However, if you want a part sew in, then fewer bundles are needed.

Your Desired Hair Volume

Not unique but important factor is how full you wish your hair. If you want much volume, you can buy more bundles without any leaving out. If you only need part sew in, you can buy less bundles.

Comparison of Length and Weight for Various Bundles

Bundles from KN hair 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.

Is 3 Bundles Of Hair Enough For A Full Head?

Yes it is! Usually, most people use around 3 bundles of hair to achieve their desired hair style. Although that is the case, still the factors above are less or more determinants of the number of bundles. Each bundle is about 100grms that means for 3 bundles its 300grms.

It is clear to see the comparison between 3 bundles and 4 bundles. The main difference is that with 4 bundles you can achieve a much fuller look especially if you like big hair. With 3 bundles it is the exact opposite.
