This product made my head burn and itch. I used it a few years ago and it was fine but the colour was difficult to find (Ginger Twist). I found it recently on Amazon and ordered 4 boxes but the dye made my head itch and I have a burning sensation. It is painful. I have tried to contact Loreal butIt is impossible to reach anyone ... Loreal USA were very nice but they don't deal with Canadian customers and Loreal Canada doesn't even have a real person answering the phone.
