The Root Renewal Serum restores and maintains your authentic hair fullness. The benefit of using this treatment serum is thicker, revitalized hair that is stronger and easier to manage and shape. The Root Renewal Serum has dual action: it maintains your hair’s fullness, and improves your hair’s health. More hair density can be experienced in the first month of use, with dramatic and lasting results in 90 days. We hear our male friends and consumers talk about renewed confidence, a turning-heads appearance, about being seen and complimented, and about loving the way they look and feel.
