Just read this
My hairdresser uses Loreale and told me they had changed the ingredients recently. I have never been allergic to anything in my life and have dyed my hair several times but when he did a skin test (thank god he did) the skin went red and started peeling off in hours. He said a couple of other clients who had been fine with the dye before had a reaction in the last few months.
Since then I have been super sensitive to shampoo to the point I get red sores down my hairline and my scalp bleeds and is covered in flaky itchy skin (the skin test was 5 months ago).
Anyone else used this and had problems? I am going to write to Loreale but I thought this post might serve as a warning. Please do a 48 hour skin test!
