How it works
The Professional Application, Step by Step
Know exactly what happens in the chair before you book, so you can plan the appointment and the maintenance around it.
-
01
Color match and plan the rows
Your stylist matches your shade and maps how many rows the look needs and where each one sits.
-
02
Create the anchor
A small braid or a beaded row is created across the section to give the weft a secure, flat foundation.
-
03
Cut to width and sew
The weft is cut anywhere along its length without unraveling, then hand-sewn onto the anchor. No glue, tape or heat.
-
04
Blend and finish
Rows are cut, layered and blended so the ultra-thin seam stays invisible even in movement.
These extensions are a professional product. Application and removal should be carried out by a trained stylist to protect your natural hair.
Before you book
Is This Method Right for You?
A great match if
- You want maximum volume from the fewest attachment points.
- You want wefts cut to the exact width of each section.
- You prefer a method with no adhesive, keratin or heat.
- You want to sleep, work out and tie the hair up comfortably.
Worth considering
- Very fine hair needs fewer rows placed lower on the head.
- The install takes longer than tape-ins.
- Rows sit slightly higher than strand methods on very short crops.
Make them last
Caring for Your Extensions
This is 100% Remy human hair, so it responds to care exactly like your own. A simple routine is what keeps a set wearable for months.
Do
- Wash with sulfate-free, alcohol-free products, no more than 2 to 3 times a week.
- Brush with a loop or soft-bristle brush, holding the hair above the attachment point.
- Keep conditioner and masks on the mid-lengths and ends only.
- Dry the attachment points fully before sleeping or tying the hair up.
- Always use heat protectant and keep hot tools below 180 C / 356 F.
Avoid
- Brushing from the roots down instead of working upward from the ends.
- Applying conditioner, oils or masks directly on the attachment points.
- Sleeping on loose hair. Braid it or tie it in a soft, low ponytail.
- Chlorine and salt water without a protective leave-in barrier.

Q & A

Frequently Asked Questions
What is a genius weft?
A genius weft is an ultra-thin, cut-anywhere weft with no return hair and no thick seam, so it lies completely flat against the head and can be cut to any width without unraveling. Each pack holds 50 g of 100% Remy human hair in 16 in or 20 in, across 15 shades.
How is a genius weft attached?
It is hand-sewn onto a small braid or a beaded row. It is installed without glue, tape or heat, which is why the same wefts move up with you.
How long do genius wefts last?
The recommended move-up is every 6 to 8 weeks as your hair grows. The wefts themselves are reusable across multiple move-ups when washed and stored correctly.
How many packs of genius wefts do I need?
One 50 g pack usually covers a single row of volume. Two packs are the common starting point for length plus fullness, and three or more create a full transformation on thicker hair.
Genius wefts or tape-ins, which should I choose?
Choose genius wefts for high volume from few attachment points and full width customization. Choose tape-ins for the fastest install and the flattest panel.
