Nioxin has rolled out new Night Density Rescue with breakthrough “NIOXYDINE24” technology, which the brand says is clinically proven to promote hair density by providing powerful antioxidants to the scalp surface. The new treatment, inspired by Nioxin’s skin care approach to hair care and the body's nightly regeneration cycles, enters a new era of skincare for the scalp, delivering a 24 hour approach to thinning, according to the P&G-owned brand.
 
Recent studies have shown that free radicals in the environment can trigger scalp oxidation and ultimately, hair thinning, Free radicals are unstable molecules that in an attempt to become more stable, steal electrons from other molecules which results in oxidative damage. This process is similar to the skin damage caused by the sun. To combat and minimize this damage in the world of skin care, there are a multitude of night time product regimens that both protect and repair skin. As night is the optimum time for the body to rest and repair itself, this is a prime opportunity to treat the hair and scalp as well.
 
Nioxin’s Night Density Rescue ($45) is a leave-on treatment that delivers antioxidants to the scalp, including biotin, caffeine, vitamin E and ginger root extract.
