**Q: What exactly is scalp surface oxidation?**
A: To answer your question about Nioxin Night Density Rescue concerning the scalp surface oxidation and what it is exactly the following will explain more.
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. This is why we recommend our Nioxin Night Density Rescue to assist with repairing the scalp from damaged oxidative issues. I hope this was helpful to you. Have a Beautiful Day!
