Our hair contains proteins held together by bonds, and when exposed to chemical treatments, styling, coloring and extreme weather conditions, these bonds can break down. This is what may cause your hair to be dry, frizzy & brittle. This bi-phasic serum and protein hair treatment for damaged hair from Dove, part of our Bond Repair line, is infused with micro oil molecules that deeply nourish, provide protective sealing, and extreme shine for vital and more lively hair. Enjoy 10 transformative benefits* from our latest innovation for 2X smoother hair, frizz control for 72 hours, heat and UV protection, color vibrancy, humidity protection, extreme shine for 48 hours, 91% less split ends, and protection for hair bonds from future damage. All this while also nourishing and giving your hair its natural bounce back. This repairing hair serum works in harmony with the Bond Repair shampoo, conditioner and serum mask to transform each strand from the inside out. Our formulas work to visibly reduce signs of chemical damage and stop future damage in its tracks. Embrace the transformative power of Dove and witness your smooth hair bounce back to life with a healthy, glossy shine. *With the use of shampoo, conditioner, and oil of the line, compared with shampoo without conditioning ingredients.
