Revlon Flex Extra Body Building Protein Conditioner is a hair care product that is designed to help add body and volume to fine, limp hair. The conditioner contains protein, which helps to strengthen and nourish hair and adds body and volume to hair. It also contains other ingredients such as panthenol and wheat germ oil, which help to moisturize and protect hair from further damage. This conditioner is particularly beneficial for those with fine, limp hair, as it helps to add volume and thickness to hair, leaving it looking fuller and more voluminous. To use, apply a generous amount of conditioner to wet hair, focusing on the ends and avoiding the scalp. Leave the conditioner on for a few minutes, then rinse well with water.
