Both Night Density Rescue and Anti-hair loss Serum help reduce hair loss, but via a different mode of action and hence responding to different needs.   Night Density Rescue works as an antioxidant treatment with its blend of antioxidant ingredients like vitamin E and Ginger, while soothing the scalp with Panthenol and Lauric Acid. It is designed to be used during the night, when our body is in a “recovery” mode, to support the natural skin renewal process and fight free radicals. Since scalp oxidation is a common cause of hair loss, Night Density Rescue helps to fight hair fall and hence increase hair density with constant use.   Nioxin Anti-hair loss serum, on the other side, is an intensive treatment designed to act on hair anchorage into the scalp. This thanks to its unique combination of Sandalore, Caffeine and Lauric Acid, working directly at the hair roots keeping them well anchored to the scalp, hence reducing hair loss. In addition, thanks to Niacinamide, this product delivers also an instant effect, by thickening the hair after the very first use.
