Description: This ultra-lightweight, colour-safe hair oil provides heat protection while fighting frizz and smoothing hair. Packed with nutrient-rich oils, it hydrates the hair while adding softness and shine, and is scented with Rue St. Honoré, a French-inspired fragrance.

Key Benefits:

  • Provides heat protection up to 232°C
  • Fights frizz and smooths hair
  • Adds softness, shine and hydration
  • Colour-safe formula
  • Helps protect hair fibres from colour fading due to UV exposure
  • Free from parabens, phthalates, SLS and SLES

How to Use: On wet hair, apply one pump from eye level down, focusing on the mid-lengths and ends, then comb through and style as usual. On dry hair, emulsify one pump between your hands and smooth through the mid-lengths and ends, adding more if needed.

  • Cruelty-Free: This brand is certified Cruelty-Free through the Leaping Bunny program; it has therefore committed never to conduct, commission, pay for, or allow tests on animals at any phase of development, for both ingredients and final products
