What it is: An ultra thickening range harnessing pioneering ingredients and technology to deliver a powerful hair-loss-fighting treatment shampoo.What it does: The patented, lab formulated PRC PLUS compound contains twenty active ingredients, including high percentages of these four, key clinically trialed blends: baicapil, capixyl, redensyl and procapil. A further sixteen dynamic, plant-based and laboratory-formulated extracts work together at both cellular and dermal levels to modulate DHT, inhibit 5-α reductase, strengthen anchoring proteins and fight the follicle aging process-stimulating growth, increasing density and allowing the recovery of a younger, thicker and healthier look. Pioneering innovation includes a newly discovered molecule called dihydroquercetin-glucoside (DHQG), a compound derived from plant extracts. When this biological component is combined with water, zinc and glycerin, it targets the hair follicle, encouraging the division and proliferation of the stem cells that directly lead to hair growth. How to use: Massage a nickel-sized amount into wet hair and scalp. Rinse. Suitable for daily use. Made in the USA
