What Customers Are Saying

Users frequently report less shedding, healthier-feeling hair and more visible volume when the full System 4 routine is used consistently. Others see healthier shine without new growth or find the system drying, strongly scented or expensive. Customer feedback summarized from exact-product Nioxin, Ulta and Walmart reviews.
