OPTI shampoo targets hair thinning and hair loss concerns with two powerful patented ingredients, Procapil® and Capixyl™, that are clinically proven to promote healthy hair growth and restore fullness and vitality. These plant-based ingredients extend the anagen (growth) phase of the hair cycle while minimizing the telogen (resting) phase. This elongated growth period enables hair to flourish, resulting in thicker, fuller, and healthier strands.
