You'll still spot all of the amazing bond-building technology that Olaplex's products are known for in the No. 8 Bond Intense Moisture Hair Mask, but its secret weapons are actually two skin-care hero ingredients: ceramides and hyaluronic acid. The former strengthens and maintains your hair's natural barrier to retain moisture while the latter hydrates your hair by holding up to 1,000 times its weight in water, leaving you with a glossy head of hair that feels as great as it looks.
