What it is
This straightening treatment refill contains two repair ingredients to reduce frizz and kinks. Acid-heat care ingredients penetrate deep into the hair, leaving it moisturized and straight. Straightening ingredients also target damaged areas inside the hair, correcting kinks and waves. The straightening bond system conditions the cuticle, leaving hair healthy and resistant to humidity. Bergamot and sweet lily of the valley scent. *This product is a refill; the bottle is not included.
