Nioxin Age Defense Conditioner is a lightweight daily conditioner that helps protect and strengthen ageing hair. Designed to support more resilient, youthful-looking strands, it helps reduce breakage and improve manageability from root to tip.
The creamy texture glides through hair, coating each strand without weighing it down, and rinses clean for a soft, smooth finish. With regular use, hair feels easier to detangle, looks more polished, and appears fuller and more supple. Ideal for mature or thinning hair that feels fragile, dry, or rough, this conditioner is perfect for everyday use after shampooing. Use it as part of your Nioxin routine to keep hair feeling nourished, conditioned and more resistant to daily wear and tear.
