Spectral.uhp is clinically proven to regrow more hair. This solution with Minoxidil 5% is the #1 dermatologist-recommended treatment for thinning hair. It's the only hair regrowth treatment clinically proven to regrow hair.* When you use the Spectral.uhp solution every day, you can revive your hair follicles. Minoxidil is a potassium channel opener, causing hyperpolarization of cell membranes. By widening blood vessels and opening potassium channels, it allows more oxygen, blood and nutrients to the follicles. This may cause follicles in the telogen phase to shed, which are then replaced by thicker hairs in a new anagen phase. For best results, use daily. Use with Revita Shampoo and Revita Conditioner (both sold separately). First and foremost, Ds Laboratories is a technology company aggressively focused on innovation. All their products have active pharmaceutical ingredients that help ensure the best quality and provide high added value in the care of hair problems.
