Bond Builder Split End Remedy helps to protect and strengthen existing bonds and repair broken bonds while sealing split ends for stronger, visibly healthier hair. The result lasts up to 3 washes and forms a protective shield on the hair that helps prevent future damage from UV rays, pollution and heated styling tools. Application: Start with a pea-sized amount and distribute through the mid-lengths and ends of roughly towel-dried hair. Pay particular attention to the most damaged areas. Apply more for thicker or more damaged hair. For best results, blow-dry the hair into the desired shape. Hair can also be left to air dry. Reapply at least every third shampoo.
