Hair bundles. You may have heard of this term, but what exactly does it mean?

Between picking the right hair type and having a proper installation, knowing more about bundles of hair will be of your benefit. Specifically knowing the products you plan on using helps the entire process go smoother. 

Let’s take a look at the specifics of hair bundles.

What are bundles of hair?

Hair bundles are exactly what they sound like – a collection of hair gathered together to create individual chunks of hair that can be sold. 

A specific amount of hair is collected and sewn together to make a strip of hair also called a weft. Bundles typically weigh around 4oz which doesn’t seem like much but it adds up after multiple are combined.

Hair bundles are surprisingly customizable. You have the option to alter the type of hair that is used, length, and sometimes even the density.

Bundles of hair are relatively cheap and a great choice for most styles. Expect to purchase at least 3 bundles when completing an install. It’s generally cheaper to purchase bundles in a set instead of individually.

Where do hair bundles come from? 

Depending on the type of hair you get you can expect a variety of different origins. If the hair is virgin human hair that means it came directly from a donor who never processed their hair in any way.

There is also the possibility that the hair is remy. This means the hair was collected in a very specific way and the cuticles are all intact. This results in some of the healthiest hair available and it’s sure to last you a long time.

The hair type you purchase can also affect where the hair comes from. There are types such as Peruvian, Indian, and Malaysian. While not all of these hair types come from their country of origin, many of them do.

How to Install Bundles of Hair

The installation method can vary greatly depending on how long you want the look to last. The installation may also vary if you are getting it professionally installed or doing it yourself.


Sewing in bundles of hair is one of the most common installation methods. Typically this is done by a professional but can be done on your own.

  • Your hair needs to be braided or secured flat in some alternative way.
  • Start at the nape of the neck and start sewing the hair into your natural hair.
  • Once you get to the hairline switchback and continue sewing until you’ve completed the bundles.
  • Continue all the way up to the top of the head and either secure with a closure or style your leave out.


Bonding, also known as gluing, is a fast and easy way to install bundles of hair. It’s best to have this method professionally done as you can’t see the back of your head and it’s easier to mess up compared with sewing.

If you choose to install it with glue you have a few options. You can utilize a quick weave which allows you to attach the bundles to a base via glue or you can glue directly to your head. The second option requires you to know exactly what you’re doing to avoid any damage.

Typical bonding install

  • Part the hair horizontally.
  • Cut the weft to the length of the parting.
  • Glue and attach the bundles of hair. 
  • Repeat until you reach the top of the head and secure with either a closure or style leave out.
