WEFT CONSTRUCTION GUIDE
Hair Weft Types: Construction Questions Before You Source.
Market labels help organize a conversation, but the physical track and written handling instructions decide whether two samples are comparable.
QUALITATIVE COMPARISON
Compare the track, not only the name.
| Weft Type | Construction | Thickness | Cut Flexibility | Typical Professional Use | Key Quality Questions |
|---|---|---|---|---|---|
| Genius Weft | Often marketed as a thin track; the exact bonding and reinforcement method needs verification. | Often positioned as low-profile; confirm against the physical reference. | Some products are sold as cuttable, but the permitted cut location and sealing requirement are product-specific. | Professional installations where track profile and flexible placement are being compared. | How is the track reinforced, where may it be cut, and what handling instructions accompany the sample? |
| Hand-Tied Weft | Hair is tied along a track; construction details and reinforcement can differ. | Often compared for a fine track, but the physical build controls the result. | Do not cut unless the supplier identifies a permitted method for that exact construction. | Professional rows where the stylist has confirmed the construction and installation method. | What prevents unraveling, which areas can be altered, and how should the ends be secured? |
| Machine Weft | Hair is sewn by machine into a track whose layers and finish may vary. | Can present a more substantial track; compare the actual sample rather than the category name. | Cutting and end-securing instructions depend on the track construction. | Professional use where track structure and handling suit the planned installation. | How many sewn layers are present, how are ends finished, and what shedding is observed after handling? |
| Butterfly Weft | A market label used for constructions intended to balance track profile and volume; the build is not universal. | Must be assessed from the sample because suppliers may use the label differently. | Confirm whether, where, and how the exact track may be divided. | Professional comparisons where the stylist needs a specific fold, track, or placement behavior. | What does the supplier mean by the label, how is the track assembled, and which instructions are written? |
CUTTING BOUNDARY
Cutting instructions belong to the exact sample.
Before altering a track, ask the supplier to identify the construction, permitted cut locations, end-securing method, and any handling condition that applies. A rule from one product should not be carried over to another product with the same category label.

Record what the sample can and cannot show.
A sample can support observations about received construction and handling. It cannot by itself establish repeat-production consistency, later processing, or every installation outcome.
