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; all different words to describe damaged hair. With a new patented technology, Dove Bond Repair Shampoo brings you expert hair repair help. Powered by breakthrough Bio-Protein Care+ Peptides, this strengthening shampoo is the first step of a four-step regime to help reduce visible signs of chemical damage, helping to strengthen your hair’s bonds from the inside out. Enjoy hair that is 2X* softer and smoother and 10X stronger, and absolutely full of life. When used as part of the four-step Dove bond repair regime, which includes a conditioner, mask, and serum, this shampoo will visibly repair signs of extreme damage, giving you healthy, smooth hair. Directions of use: Massage on wet hair and rinse. Apply again if necessary.
