I absolutely love this Nexxus humectruss hair conditioning mask. I picked it up at cvs for around $3 and they also had a special that was buy 2 get one free. It suggests that it’s left in hair for 3-5 minutes. So, after shampooing, I applied the mask and put a conditioning shower cap on my head to keep it in. I shaved my legs and then rinsed. My hair is so soft and shiny !!
