hair cycle. Many new cosmetic treatments have been reported, including stemoxydine, Nioxin, minoxidil, and a leave-on technology combination: caffeine, niacinamide, panthenol, dimethicone, and an acrylate polymer (CNPDA). This treatment has shown to increase the diameter of existing, individual scalp hair fibres by 2–5 μm, yielding a significant increase of approximately 10% in the cross-sectional area of each hair. Additionally, CNPDA-thickened hairs also demonstrate altered mechanical properties of thicker fibres; increased suppleness/pliability, and increased ability to withstand force without breaking.
