What it is
The Goddess Beauty Series will give you goddess-like, manageable, shiny hair.** This series contains DGA (diglucosyl gallic acid), an ingredient that adheres to the cuticle on the surface of your hair to reduce dryness while also working on the inside of your hair to make damaged hair supple. DGA is also used in salon products. Furthermore, when used in the series, it locks in the beauty ingredients of the hair serum* for a powerful pack effect, giving you goddess-like, manageable, shiny hair. *Isostearic acid (hair repair ingredient) *This product is a refill, so the main product is not included.
