VO5 Extra Body Volumizing Shampoo targets fine or compromised hair through a deep-cleansing formulation that removes weight-inducing buildup while delivering the brand's 5 Essential Vitamins™ complex—E, H, C, B5, and B3. This 15 oz formula enhances perceived thickness and natural body through scalp and strand nourishment without silicone-based coating. The volumizing action addresses root-to-tip cleansing efficacy while maintaining sustained lift throughout daily wear. Ideal for those with naturally thin hair or those experiencing flatness due to product accumulation, seeking clinically-formulated volumization without compromising hair health or manageability.
