I first tried the Head First Restoring shampoo at the Farmhouse Inn - a luxury hotel in Forestville. I did not bring my own shampoo so I tried this. Please note, I am super picky and rarely use the products that a hotel provides but I was in a rush packing. Washing and conditioning felt good but it was when I went to style my hair when I noticed how hydrated and shiny my hair looked. It appeared more youthful, fuller, and softer. Mind you, I am on the road to 50 and my hair is fine + thin. Once I got home I ordered this and the Head First conditioner. I am hooked! This is the fountain of youth for my hair.
