Recently I bought the Volumizing Reflectives Bliss thermal protector, after a trip to the salon. My hair is quite healthy but is also thin in texture and a little bit frizzy at times. Previously I used the dove heat protector but prefer this make so much more. It has a very aromatic smell, does not weigh down my hair and is a great detangler/leave in conditioner. After when I have blow dried my hair it really has a lovely shine to it and feels very soft and manageable. It claims that it also protects the hair from environmental stressors, as well as mechanical and thermal.I also left my hair to air dry after using this and it looked like it had more volume and very shiny too. Even though I paid Â£13 for it, I think it is a real investment as it will last me for ages as you only need a couple of sprays. I will try the system 1 next and will add a review.
