Hello ladies, I just purchased the Nioxin Silk Elixir last night at Ulta and I was wondering how to use the product for a roller set.  Do I apply the product to my whole head prior to rollersetting or should I apply the product to each section as I roll?  Should I use a serum with it? Any suggestions would be greatly appreciated.  Thanks
