I got this within a week of ordering, so it's quite good. The price on amazon was also the cheapest around. With its raving good reviews, I was looking forward to get my hand on this product since I have just got my first ghd gold styler like YEA!
I sprayed like 4-5 times on my thick damp hair before blow-drying and WOAH WOAH WOAH! My hair wasnt dried out and twig-like after blowdrying and the effect was really of salon standard. I have never been so pleased with my hair before. HOWEVER, five minutes later, I started to experience itching on my back, shoulder and the side of my face. Turned out, my skin developed allergy symptoms as my long hair swished about my skin. By the next morning, it was full-blown rash all over. I quickly washed my hair and blow-dried it without using this thermal protector, and the rash quickly went down a few notches by evening. So, while it was effective in protecting my hair, it did terrible stuff to my skin. So... guess it's not for me! :(
