Designed to work at a molecular level, the Bond Repair Conditioner replenishes lost lipids in the hair cell membrane complex, which act as glue to hold hair structure together, helping rebuild broken hair bonds at the molecular level**. Heat styling, colouring, humidity, sun exposure, and even brushing hair damage hair bonds, making the hair weak. Powered by Pantene’s proprietary Melting Pro-Vitamin B5 Formula, the conditioner contains 5,000 Pro-Vitamin B5 pearls, which melt instantly upon application, infusing millions of nutrient molecules.
