Genius Weft

No return hair, no bulk

Genius Weft

The flattest sewn weft we make. Nothing is folded back into the seam, so there is no double thickness at the root — and you can still cut it anywhere without shedding.

How it works

Three steps, start to finish

01

Match your shade

Send a photo in natural light and a stylist matches you by hand, free. Or order a colour ring and hold every shade against your own hair first.

02

Cut to the row

Measure the section, cut the weft to match, and the edge stays put. No sealing, no fraying, no lost strands.

03

Bead, sew and wear

Anchor the row with beads and sew the weft on with thread. A full head goes in in about forty minutes and moves up every six weeks.

Build your kit

How many wefts do I need?

1–2 wefts · Fill

Fill a thin area

One row through the back, placed where your own density drops off. Enough to close a gap without changing how your hair hangs.

Shop the collection

2–3 wefts · Half head

Thickness through the ends

Rows across the back and sides so your mid-lengths and ends stay thick to the tip instead of tapering off. The most requested build.

Shop the collection

3–6 wefts · Full head

The full transformation

Rows from the nape to the crown. With no bulk at the seam the weight starts high and falls in one piece.

Shop the collection

Head sizes and density vary. Send us a photo and we will confirm your shade and how many wefts to order, free.

The detail

Engineered down to the last detail

No return hair

Nothing is folded back and stitched down, so the seam carries one layer instead of two. That is where the flatness and the light weight come from.

Cut anywhere, no shedding

The construction holds a cut edge on its own. Size each row to its section and nothing works loose over the six weeks you wear it.

12A, double drawn

Salon-grade virgin Remy, cuticles all running one way so it never tangles on itself, with the short hairs drawn out by hand so it is as thick at the end as it is at the root.

Ouielle shade range

Colour

Find your exact match

A perfect install still shows if the colour is wrong. Ouielle shades are mixed to sit against real hair — ash without green, black without blue, blonde without brass — and matched to your photograph by hand.
