NuGene International has introduced a reformulated variant of its hair fortifying serum Revellus to haircare buyers and salons. Formulated with the firm's proprietary stem cell technology, the serum is claimed to aid vitality of the scalp and make hair appear fuller, thicker, and voluminous. The serum is formulated using Human Stem Cell Derived (HSCD) proteins, derived from the company's patent pending adipose-derived stem cell culture process, and a blend of antioxidants, natural extracts, and peptides. The resulting formulation is claimed to address nutrient needs of the hair to revive scalp and nourish follicles for a volumising and young appearance. Revellus is also claimed to be free of fragrances, colour additives, parabens, sulfates, propylene glycol, and phthalates.
