    Q&A

    At what point do you apply this? After shampooing? Before? After conditioning? Thanks!
    Hi, the Repair Treatment Masque can be applied on dry or damp clean hair. We generally recommend applying on damp, towel-dried hair after shampooing, and you may not need to use a separate conditioner after depending on your hair needs.
    Can this be used in place of a regular conditioner? I wanted to purchase the Volume conditioner but am looking for a silicone-free conditioner. Thanks!!
    We recommend using the Repair Treatment Masque as more of a weekly treatment/deep conditioner rather than a standard conditioner. How often you want to use it may depend on what your hair type allows!
    Does this product have silicone in it?
    This product is silicone free!
    How often is this product to be used?
    Hi, we recommend using the Repair Treatment Masque about once a week, but you can use it more or less often depending on your hair needs!
    can I leave it overnight?
    Yes!
