Fusio Dose. If your stylist hasn’t mentioned this customizable treatment to you during a shampoo experience, they’ve done you a disservice. It is that incredible. Your hair deserves a beauty ritual as lavish as this, and you are worthy of a treat! In this service, your stylist will have a conversation with you about what issues you’re having with your hair. Whether it’s dry, fine, or overprocessed, there’s a combination for you. While it’s a quick process, it packs quite the punch! Working from within the cuticle, the effects are long-lasting.
