I was given a thank you gift from my employer some time ago and L'Oreal Kerastase Fondant Nutri-Thermique was one of the luxury items I received. Before I used it, I had no idea how transforming and effective the product was. Once I used it, I became a believer! I have had so many colors, (permanent and semi-colors), perms and treatments done to my hair over the years my hair had become somewhat dry at the ends. I was intrigued by this particular treatment because it required an element of heat to work at it's most effective. I washed my hair as usual and then left the product in for 30 minutes while I did housework. I worked up quite a sweat during this time, hence the heat, and was amazed at the after-result. My hair was the softest it had ever been, it looked shiny, healthy and new again - it rather resembled the most unspoiled baby hair! I was hugely disappointed when I had finished the tub of Kerastase because I could not justify spending so much money on deep conditioner.
