Before / After


  1. Smooth evenly through hair, combing with fingers if needed.
  2. Chill out for 5-10 minutes, then rinse.

Headed to the gym or spa? Work the treatment through strands before a sweat session and let the heat help it penetrate your hair, then rinse.

Treatment Masque #Yourouai


  • How do I use the Treatment Masque—wet or dry hair? Can I sleep in it overnight?
  • The Treatment Masque can be used on wet or dry hair and can be slept in over night. Pro-tip: We love to multi-task by applying it before a workout and letting the heat in the room help it absorb.
  • I have fine hair, will the Treatment Masque weigh it down?
  • Unlike some treatment masques that use heavy silicones to mask damage, our Treatment Masque is formulated with smart keratin and tamarind seed extract, which weightlessly rebuild the hair’s protein makeup without making it heavy.
  • I love the smell of the Treatment Masque, what scent is it?
  • The fragrance is Melrose Place, the same fragrance as our Rose Hair & Body Oil. It contains notes of Rose, Bergamot, Lychee, Cedar-wood, and White Musk.
