R HAIR CARE Death of hair-producing cells Rousselot’s collagen peptides, for example,
are the ultimate expression of its approach to ingredient development. The collagen peptides are safe, bioactive, and they are optimized to be easily digestible, highly bioavailable and effective in delivering holistic beauty benefits. What is more, the collagen peptides are
easy to work with in nutricosmetic product applications. Its neutral sensory profile, even in high concentration, superior cold- and warm- water solubility, heat resistance and transparent appearance when dissolved, means it can be seamlessly incorporated into a wide range of formats, spanning from ready-to-drink beverages to concentrated shots, gummies and snacks. This versatility is truly valuable in the context
of hair care products, where convenience and aspirational lifestyle qualities are often as important as functionality. With solutions like this at their disposal, brands can take consumers’ hair care goals from the realm of distant fantasy, to tangible reality.
