I got recommended the GHD straighteners from my hairdresser and found the result after applying the hairdresser also really great. Unfortunately, the device that I then receive nothing at all! My hair is completely burned at the tips and straw-like, although the unit actually should automatically adapt to the hair structure ... Because different result at the hairdresser and my previous 3 tests at home (with heat protection of John Frieda and I'm not the first time a flat iron in his hand had) so so, is that I just a faulty device, I get the suspicion, have caught ... But for the price that's just not acceptable! Am pretty disappointed and must now first look in my hair again halfway repaired get!
