Pleasant smell easy to use.

I have been using the Nioxin night density rescue serum for almost 4 weeks. It feels refreshing on the scalp and has a nice and airy scent. It does not sting or leave a residue. It is not oily, more watery than oily and it does not make hair oily. As to the effectiveness, I noticed my streams abeing a bit thicker, but did not notice any new growth or drastic changes. I would need to use it longer to give a more thorough review.
