The “Infinite Knot”: Karim Belghiran Breaks Down Cult Gaia’s SS27 NYFW Runway Hair

09/10/2026

The very clear hero hairstyle from the Cult Gaia SS27 runway was the “infinite knot.” Created by Celebrity Stylist Karim Belghiran for TRESemmé, the look is all about fluid movement, softness and a chic af, elongated knot.

Belghiran says he was “inspired by a dreamlike woman in a dream world,” and that the hairstyle “embraces softness, movement, and effortless beauty.” He shares that the look embraces “wispy texture and an undone, looped knot create a romantic finish. Light, delicate, and easy.”

Get the Look:

  1. Prep hair with TRESemmé Protecting Heat Styling Spray before curling hair with an iron to enhance the hair’s natural texture.
  2. Use your fingers to help smooth the hair while blow-drying.
  3. Spray TRESemmé Extra Hold Hairspray onto your hands and run your hands through the hair to reduce frizz and create a more polished finish.
  4. Create the knot in the hair, using a little TRESemmé A-List Collection Dry Texturizing Spray to help maintain the shape.
  5. Finish with a small amount of TRESemmé A-List Collection Bonding Oil on the ends to add hydration and a subtle shine.
