Our Gentle Care shampoo is made from naturally derived hair-protein friendly foaming agents that are gentle on your hair and scalp. But, what makes Himalaya's Gentle Daily Care shampoo perfect for everyday use? Natural foaming agent: Most shampoos consist of chemical-based foaming agents that are harsh on keratin or the hair's natural protein fibers. Himalaya's Gentle Daily Care shampoo has a foaming agent derived from natural ingredients. This natural foaming agent is safe and gentle on the hair and scalp, protecting the hair's natural keratin. The natural foaming agent also smoothens hair and cleans effectively yet gently. Supports normal oil secretion: Most shampoos contain synthetic ingredients that produce a 'build-up' effect on the scalp when used daily.
