What is a genius weft?

A genius weft is a very thin machine-sewn weft that your stylist can cut to the width of each row. Your stylist sews it onto a row of micro beads, with no glue or heat, so it sits flat and close to the scalp.

Who are genius wefts best for?

Genius wefts suit medium to thick hair and anyone who wants seamless volume. Because each row is long and flat, they give a lot of fullness from a few rows and are comfortable to wear.

How many packs do I need?

Each pack is one 50g weft. Two to three wefts (100–150g) give natural fullness and three to four (150–200g) a fuller finish.

How long do genius wefts last?

The hair lasts 12 months and more with care. Your stylist moves the rows up every 8–10 weeks, reusing the same wefts.
