I have (virtually all drug products) to very expensive (eg Kerastase, almost twice as expensive as ghd Hitzeschuzt) tried everything possible already from very cheap and have decided in the end for the heat protection spray of ghd. It complains not the hair, not glued it and the hair smell fresh. Even after 2 days the hair act not greasy. I also feel as if the hair is not sooo out quickly by the Hitzschutzspray as with others. But one thing is clear: to ruin the hair straighteners, no matter what you used Hitzschutzspray!
