Genius Weft vs Hand-Tied Weft
Updated 2026-09-25. By Devan, hair extension specialist.
Genius wefts are thin, flexible machine wefts that can be cut to any width without shedding, so they fit the shape of your head closely. Hand-tied wefts are also thin and soft but cannot be cut, so they come in fixed widths. Both sit on a beaded row with no glue or heat.
Which looks more natural?
Both lie flat. Genius wefts have no return hair at the top of the track, which helps them sit very close to the head, especially near the hairline.
Which is more comfortable?
Most clients find them equally comfortable. Genius wefts can be trimmed to the exact width of your row, which avoids pressure at the ends of the row.
How much hair do I need?
About 100g for one row of volume and 150g to 200g across two rows for a full, long look.
Questions
Can genius wefts be cut?
Yes. They can be cut anywhere along the weft without unraveling.
Can hand-tied wefts be cut?
They should not be cut between the tied sections, because the weft may unravel.
