Choosing the Right Hair Weft: Genius Weft vs Machine Weft vs PU Weft vs Flat Weft vs Handtied Weft
When it comes to hair extensions, the type of weft you choose makes all the difference in how natural, comfortable, and long-lasting your results will be. Let’s break down the differences, pros, and best uses for the top five types of hair wefts in today’s market.
1. Genius Weft
A revolutionary thin weft with no return hair and an ultra-flat, flexible design. It combines the best qualities of hand-tied and flat wefts.
Advantages:
- Ultra-thin and invisible: Lies flat on the scalp for a seamless look
- No return hair: No short stubble = no irritation or tangling
- Can be cut anywhere without shedding
- Durable yet lightweight
Best for: Clients who want the most natural and comfortable weft that’s easy to customize.
2. Machine Weft
A traditional weft sewn by machine. It has a thicker band and visible stitching.
Advantages:
- Durable and strong
- Can be cut anywhere on the weft
- Cost-effective compared to hand-tied or genius wefts
- Good for thick hair and volume installs
Drawbacks:
❌ Thicker and more detectable under fine hair
❌ May include return hair that causes itching
Best for: Clients with medium to thick hair who need volume and don’t mind a more structured install.
3. PU Weft
What it is: Hair is injected or sewn into a thin, flexible PU (polyurethane) strip, which mimics the scalp.
Advantages:
- Smooth and soft band
- Virtually undetectable when installed properly
- Waterproof band
- Can be cut anywhere without shedding
Drawbacks:
❌ Not breathable, can trap heat and moisture
❌ Needs specific installation methods like tape or bonding
Best for: Clients looking for a super flat look under fine hair, or those with sensitivity to return hair.
4. Flat Weft
What it is: A machine-made weft with a compressed, flat top, designed to lay flatter than traditional machine wefts.
Advantages:
- Thinner than machine wefts
- Can be cut without unraveling
- More breathable than PU wefts
Drawbacks:
❌ May still include return hair
❌ Slightly bulkier than Genius or hand-tied
Best for: Stylists who want something thinner than machine wefts but easier to work with than hand-tied.
5. Handtied Weft
What it is: Hair is hand-knotted into the weft. It’s delicate, flexible, and lies flat to the scalp.
Advantages:
- Ultra-flat and discreet
- Very natural movement
- Lightweight and breathable
Drawbacks:
❌ Cannot be cut (or it will unravel)
❌ More time-consuming to install
❌ Delicate — not ideal for rough handling
Best for: Clients with fine or thin hair who want an undetectable result — and stylists with experience installing them.
6. Butterfly XO invisible weft

Advantages:
- Ultra-Invisible Finish. Combines a thin PU base and injection weft technique to eliminate bulk and “tracks,” blending effortlessly with fine hair.
- Lightweight & Breathable. Designed to mimic hand-tied wefts in comfort—much flatter and gentler than traditional machine or PU-only wefts.

- Modular & Customizable. Can be cut anywhere without unraveling, and easy to layer for added thickness
