Dove Intensive Repair Shampoo is specifically designed to address the needs of damaged hair, whether from heat styling, chemical treatments, or environmental stressors. The product is formulated with what Dove calls "Nutri-Keratin Repair Actives" or "Bio-Protein Care." These active ingredients work in two ways:

Surface Repair: The formula helps to visibly repair the signs of surface damage, such as roughness and split ends, making the hair look and feel smoother.

Deep Nourishment: It also penetrates the hair strands to provide nourishment from within, which helps to strengthen the hair against future breakage and makes it healthier with every wash.

The shampoo is gentle enough for daily use and is often recommended for use with the corresponding Dove Intensive Repair Conditioner for a complete hair care system. While reviews and experiences vary, many users report that the shampoo leaves their hair feeling soft, smooth, and more manageable, with a pleasant, long-lasting scent. Some users with specific hair types, like very dry or frizzy hair, have found it effective in reducing frizz and making their hair feel lighter and bouncier.
