Hair guide
How much hair do I need?
Estimates for quoting your client, not hard rules. Longer lengths and thick or blunt natural hair may need more for a seamless blend, and only add what their natural hair can comfortably support.

Choosing a method
Every method uses the same double-drawn, cuticle-intact hair. Here's how they differ.
Genius Wefts
Thin and flat like a hand-tied weft, but solid, so it won't unravel when cut on the seam. No return hair, works on all hair types, and you can stack colors. 22" and 24" in 100g and 50g packs. Lasts 9–12 months; move up every 4–8 weeks.
Flex Wefts
One continuous machine weft built for volume. Easier to sew in, cuttable on the seam, and lays close to the scalp. 22" and 24" in 145g and 70g packs. Lasts 9–12 months.
Tape-Ins
A gentle method that lays flat to the head. Sandwich them or use single. Best for filling in, or 3–5 packs for a full head. 16"–22", 10 pieces per pack. Lasts up to 6 months. The adhesive contains latex.
K-Tips
Individual keratin bonds for natural movement and discreet, custom placement, including around the sides. 20 strands per pack. Lasts 3–5 months; removal is done by a professional rather than move-ups.
Clip-InsAnyone
No install needed. A great add-on for clients who want volume for an event.
