Machine Weft vs. Genius Weft: What’s the Difference?

Machine Weft
Classic & full-bodied
Densely sewn for maximum fullness at the lowest cost, with a thicker, more visible band that can feel bulky near the scalp.

Genius Weft
Trim-to-fit & invisible
Ultra-thin, skin-like band you can cut to any width without shedding—combining the density of hand-tied and the clean finish of injected wefts for a flat, undetectable finish with no return hair.
Care & Maintenance
- Schedule move-ups every 6–8 weeks.
- Use silicone-lined beads and durable thread; replace beads and thread at each move-up.
- Choose bead colors matching your roots for a discreet blend.
- Don’t use flare or grooved beads—silicone beads give the best grip and comfort for sew-ins.
- Don’t reuse old beads or thread—worn materials reduce hold and risk slippage.
- Don’t rip the weft out—cut all thread and fully release beads before removing.
