Hair extensions offer a solution for thin, short, or lifeless hair. Among the various options, weft hair extensions stand out as a popular choice. For beginners, navigating this field can be daunting. This guide provides essential information to help you make informed decisions about your hair transformation journey, from understanding “what are weft hair extensions” to choosing the right type, texture, and color.
What Is A Weft Extension?
What is a weft of hair? Weft hair extensions are bundles of hair sewn or machine-tied at the top to form a track. Each bundle typically weighs 100 grams and seamlessly adds volume, length, and highlights or lowlights to your natural hair. They are favored by hairstylists and enthusiasts for their natural and seamless look.

Benefits of Weft Hair Extensions
- Natural Look & Feel – Weft extensions blend seamlessly with your natural hair, offering a fuller and longer look.
- Long-Lasting & Reusable – High-quality weft extensions, especially those made from 100% human hair, can last 6–12 months with proper care.
- Less Damage to Natural Hair – Unlike some extensions that require adhesives or heat, weft extensions are sewn in, reducing the risk of hair damage.
- Suitable for Various Hair Types – Whether you have fine, thick, or curly hair, there’s a weft extension type that suits you.
- Versatility in Styling – You can style them as you would with natural hair, including curling, straightening, and dyeing (if using human hair wefts).
Best for:
- People looking for long-lasting hair volume and length.
- Those who prefer semi-permanent extensions over clip-ins.
- Anyone with medium to thick hair (for fine hair, hand-tied wefts are better).
- Stylists who want a customizable extension option for their clients.

Types of Weft Hair Extensions
Weft hair extensions come in various styles to suit different preferences and styling needs. Here are the most common types:
Machine Weft
- Description: Traditional wefts with hair strands sewn or machine-tied into a straight line.
- Advantages: Quick installation (around 2 hours) and affordable (starting at $23 per bundle).
- Ideal For: Quick transformations or special occasions at a reasonable price.

Hand Tied Weft
- Description: Hair strands are hand-tied, creating a thinner and more flexible weave.
- Advantages: More natural and flawless blend, lightweight, and comfortable.
- Ideal For: Those seeking a discrete and invisible hair extension solution, especially for finer or sensitive hair.

Flat Weft
- Description: Sewn or bonded to lie flatter and more compactly.
- Advantages: Smooth, seamless integration with natural hair, nearly invisible appearance.
- Cost: 20%-30% higher than standard machine wefts, but worth it for the refined look.

Genius Weft
- Description: An innovative extension with a thinner and more beautiful line compared to traditional machine wefts.
- Advantages: Seamless and undetectable appearance, higher quality.
- Cost: More expensive, reflecting its advanced design and superior quality.

Beaded Weft
The beaded weft is an innovative variation of hair extensions. Unlike the conventional machine weft, the beaded weft uses beads for attachment. This method involves threading a small section of hair through a bead and then securing it with the bead, ensuring stability and minimal impact on natural hair. However, the beaded weft can be more noticeable and often requires professional application, increasing the overall cost.

Step-by-Step Guide for Sew-in Method
Now that you know what weft hair extensions are, learn how to install them without looking obvious and without damaging your natural hair. Here are the instructions:
Step 1: Preparation
- Wash, condition, dry, and straighten your natural hair thoroughly to avoid tangles and ensure clarity.
- Comb all tangles out of your hair, ensuring it’s smooth and straight.
Step 2: Sectioning Your Hair
- Using a rat-tail comb, neatly part your hair horizontally at the back of your head, starting from the nape of your neck. Clip the rest of your hair away safely to avoid tangling.
Step 3: Creating a Braided Base (cornrows)
- Braid a small horizontal cornrow directly above the horizontal part you’ve just made. This small braid acts as the base where the weft hair extensions will be sewn. Keep it snug—but not too tight.
- Continue creating neat, thin rows of cornrows along the desired areas to build your foundation if you’re adding multiple wefts.
Step 4: Measuring & Cutting the Weft
- Take your weft hair extension and measure against the length of your cornrow you’ve just braided, then cut carefully to fit the braid length.
Step 5: Sewing the Weft Extensions
- Thread your needle, tying a small knot at the end.
- Hold the weft along your braided base firmly and start sewing from one end towards the opposite side, securely stitching the weft extension to your cornrow foundation, looping around the braid and weft carefully.
- Secure the stitching at the ends by knotting the thread and trimming excess thread carefully.
Step 6: Continue Adding Wefts
- After securely sewing your first weft, move upward and repeat step 2 to step 5, row by row, until achieving your desired thickness and volume.
Step 7: Blend and Style
- When the installation is complete, release your natural hair and comb carefully to blend well.
- You can style your hair extensions just like your natural hair—straightening, curling, or whatever suits you best.

Alternative Installation Methods: Glue-in or tape-in method: Simply apply glue or adhesive tape to the track of the weft, pressing firmly along your parted hair section.
(Note: If opting for glue or tape, ensure to use suitable adhesive removers when removing, and handle carefully.)
