I have been using Loreal hair colour products for over 15 years and have never had any kind of adverse reaction. Today I used the new sublime mousse for the first time. It has burnt my scalp and I am itchy all over. It has also left stains on my skin. This is the first time I have EVER written a negative review. I am very disappointed. I will not be using the mousse again, and will try other brands before giving money to Loreal. I dye my hair on a very regular basis. They have lost a once loyal customer.
