What Are Sew-In Hair Extensions?

Sew-in hair extensions are a protective style for women in which hair extensions are stitched to their natural hair using a needle and thread. These hair extensions are stitched to cornrows, which are then used as a base for these hair extensions.


Sew-in hair extensions are commonly used by hairstylists since these hair extensions are stitched to natural hair and thus do not require glue or heat to be applied to natural hair. This is beneficial in that it does not damage natural hair.


Hair extensions are weft-based bundles, which are then stitched to natural hair.

Tools You Need Before Installing Extensions

Preparation is the first step to a successful process, and the basic tools required are as follows:


  • Curved weaving needle

  • Weaving thread, matching the color of the hair

  • Hair clips, used for sectioning the hair

  • Rat tail comb

  • Scissors

  • Hair bundles/wefts

  • Moisturizing products, used for natural hair


Good quality hair extensions are a crucial factor in the final result of the process, as they make a huge difference. Many people prefer working with human hair wefts, as they are easy to blend with natural hair, unlike synthetic hair, which cannot be styled with a blow dryer.

Step 1: Prepare and Wash the Natural Hair


Healthy hair preparation is a necessity before installing hair extensions.


To begin with, wash the hair with a mild shampoo, followed by a deep conditioner. This helps ensure that the scalp remains healthy during the period of time the hair extensions are worn.


Next, allow the hair to dry completely before braiding. A light leave-in conditioner or oil should be used to keep the scalp moisturized.

Step 2: Create the Cornrow Base


As discussed, the cornrows are the base of the braids, which support the extension.


To create the braids, a rat tail comb is used to section the hair into horizontal parts. Braiding begins at the front of the head, progressing backward toward the back of the head. The braids are tightly braided but not so tight as to be painful.


A good braiding pattern for beginners is the straight-back braiding style. In some instances, a circular braiding pattern, also known as a beehive pattern, is used to ensure a more natural flow, especially when sewing bundles of weft hair extensions.


Once braiding is complete, the ends of the braids are secured with a small rubber band.

Step 3: Prepare the Weft Bundles


Prior to sewing, the extension wefts are measured against the braids.


Wefts are cut to the width of each individual braid so they are comfortable along the braids, also known as the cornrows. In some instances, the wefts are folded instead of cut to avoid excessive shedding.


For those who are connected with salons or suppliers, Machine weft hair extension supplier are used because they are more durable and easier to install, even for a novice.

Step 4: Thread the Needle


Take your weaving thread and insert it through the curved needle. Tie a small knot at the end of the thread to avoid it from passing through the braid.


The use of a curved needle is recommended since it glides through the braids and extension wefts without pulling on the hair excessively.

Step 5: Start Sewing the Extensions


Take your first weft and place it on the lowest braid at the back of the head.


Insert your needle through the braid and weft, making sure you pull your thread through so that it does not come out from the end where you knotted it. Continue sewing through the braid using a series of loops. Each loop should be about a centimeter apart.


This is where you need a lot of patience in your sewing activity. Take your time to ensure your extensions lie flat on your braids.


As you move up along your head, you will need to repeat this procedure on all your braids.


Most salon operators buy hair bundles in bulk from a wholesale hair extensions distributor in order to maintain quality for sewing services.

Step 6: Fold the Weft at the Ends


At the end of each braid, rather than cutting it, fold it in the opposite direction. By sewing through this part, it will provide a stronger hold and also reduce shedding.


Sew through the next row until all braids are covered with hair extensions.

Step 7: Blend and Style the Hair


The final stage in this guide on how to install extensions is blending.


Leave out a section of your hair at the top or on one side for covering all the wefts. You can trim them if you want them to blend well with the left-out section.


You can now style your hair in a variety of ways, including curls, straightening, or waves.

How Long Do Sew-In Extensions Last?

A good install of a sew-in usually lasts six to eight weeks, depending on proper care.

Care should be taken not to pull on the braids, as this can cause the braids to weaken at the roots.
