Types of Hair Wefts: Genius, Machine, Hand Tied, Butterfly & More (Complete Salon Guide 2026)

Hair weft extensions are one of the most popular hair extension methods used by professional stylists and salons. They offer incredible versatility for adding length, volume, and fullness to a client’s hair.

However, many stylists are often confused by the different types of wefts available on the market today. From traditional Machine Wefts to modern innovations like Genius Wefts and Butterfly Wefts, each type has its own advantages and ideal salon use cases.

In this complete guide, we will explain the most common types of hair wefts used in professional salons so you can choose the best option for your clients.

1. Machine Weft (Volume Weft)

Machine wefts are the most traditional type of hair weft extensions. They are created using industrial sewing machines that stitch strands of hair together into a thick track.

They are sometimes referred to as Volume Wefts because they typically provide high hair density.

Advantages

Very durable construction
Affordable compared to other wefts
Suitable for thick hair clients

Disadvantages

Thicker track
Less flexible during installation
May feel bulky for fine hair

2. Hand Tied Weft

Hand tied wefts are created by manually tying strands of hair onto a thin thread base. This process creates one of the thinnest weft tracks available in the hair extension industry.

Because of their ultra-lightweight construction, hand tied wefts are often used for clients with fine or thin hair.

Advantages

Very thin track
Natural appearance
Comfortable for sensitive scalps

Disadvantages

Cannot be cut
Must be folded during installation
Can become fragile after multiple move-ups

3. Genius Weft

Genius Wefts are considered one of the most advanced hair extension wefts available today.

They are designed to combine the thinness of hand tied wefts with the flexibility and durability of machine wefts.

Advantages

Ultra-thin track
Can be cut anywhere without shedding
No return hair (no "mustache")
Flexible and comfortable

Because of these advantages, many modern salons are transitioning from traditional hand tied wefts to Genius Wefts.

4. Butterfly Weft

Butterfly Wefts are one of the newest innovations in hair extension technology.

They feature a specially engineered flexible base that allows the weft to lay flatter against the scalp. This creates a seamless and more natural installation.

Advantages

Lightweight design
Flexible track
Extremely natural blend

Butterfly Wefts are becoming increasingly popular among salons focused on invisible installations.

5. Flex Weft

Flex Wefts are designed with a super flexible track that adapts easily to the shape of the client’s head.

Compared with traditional wefts, Flex Wefts are softer and more comfortable, especially for clients with sensitive scalps.

Advantages

Flexible base
Enhanced comfort
Natural hair movement

6. Flat Weft

Flat Wefts are designed with a flattened track to reduce bulk during installation.

They provide a balance between durability and thinness, making them a versatile option for many stylists.

Advantages

Flat track
Durable construction
Suitable for many installation techniques

7. Long Tape Weft

Long Tape Wefts combine the concept of tape-in extensions with a weft design.

Instead of sewing the weft, stylists can apply it using tape adhesive, which allows for faster installations in the salon.

Advantages

Fast installation
Lightweight
Good for quick salon services
