Hair weft, invisible weft, tape, keratin strands, clip-ins, halos and ponytails. The category gathers every method in wavy texture, in human hair.

The waves scatter the light and hide the transition between your own hair and the extensions. Small color differences and an overdue move-up show less than in straight hair.

A little, but nowhere near as much as curly. Expect the length to look a few centimetres shorter than the measurement when the hair is dry and unstyled.

No, that's normal in human hair. The wave comes back when you reshape it with heat or let the hair air dry in a braid.

Luxury and Premium are Remy hair with all strands running the same direction, which means the least tangling and the longest lifespan. Classic is human hair but not Remy and a good choice at a lower cost.

Tape, keratin strands and invisible weft are the gentlest on fine or thin hair. A halo is the gentlest of all, since it sits on a wire with no attachments at all.

Tape is moved up every 8–10 weeks, microrings every 2–3 months. Keratin strands last 3–4 months and are then reset. Halos, clip-ins and ponytails you take out whenever you like.

Yes, human hair can be straightened with heat protection and gets its wave back after washing.

Brush when the hair is dry, not wet, and work from the ends upward. Letting the hair air dry rather than blow drying it straight keeps the wave in shape.

Halos, clip-ins and ponytails you put in yourself in a few minutes. Tape, keratin, microrings and hair wefts need a technician – we do that in Stockholm and Uppsala.
