The DS Laboratories Men's 3-Piece Hair Density Set is a three-step hair care regimen designed to support fuller, thicker-looking hair and a healthier scalp. It includes Revita Shampoo, Revita Conditioner, and Spectral Men's Topical Serum. The system helps minimize hair shedding, strengthen hair against breakage, and improve the appearance of density and volume with consistent use. Suitable for all hair types, including curly hair, it is applied daily—shampoo and conditioner left on for two minutes before rinsing, and the serum sprayed twice daily onto affected areas. Clinical studies indicate visible improvements in hair fullness within 90 days, with peak results around 180 days.
