$11.00 / 150ml


A weightless, curl defining cream which helps nourish and protect curls.

Curly hair has more bonds of an amino acid called cysteine: the more bonds between hair, the curlier the hair is. Curly hair also tends to be quite dry and in need of moisture and hydration.

We have developed a unique technology that helps define and prolong curls' bounce and their natural shape by targeting the hair bonds, whilst providing hydration too. This weightless serum has been formulated to also help reduce, protect and strengthen hair against chemical damage and tame frizz.

  • All Hair Types
  • Colored Hair
  • Pregnancy & Breastfeeding


  • Dry Hair
  • Frizzy Hair
  • Kinks, Coils & Curls

    Really helps with frizz

    Works well with the hyaluronic acid hair treatment. I have really fine hair with very loose waves, which means I constantly struggled with frizz, no matter how I dried it or what I washed with it. These two products really helped to tame my hair.
