Attention hair loss.
I was forced to switch to a new brand after my color was discontinued. This one with the "same" number is much lighter, a bit too light for me, and above all I had hair loss for five to six weeks after using it! I even did the allergy test beforehand - no problems, I thought.
I will definitely not be using this line again. I have to hope that this is random bad luck on my part. Otherwise, be careful...
Good
