I am a middle aged woman who has become VERY allergic to hair dye over time. More than just an itchy scalp, my eyes turn red and I suffer with eczema on my eyelids. I’ve tried many different products that promise they have no peroxide, ammonia or PPD. I have even resorted to wearing goggles to protect my eyes. Each time, I suffered badly, to a point where I was spraying my roots with a root cover up and thinking I might actually have to give up and go Grey! Yesterday I tried Elumen NN@8, especially formulated to completely cover Grey. IT WORKED!! And I’m not allergic! Thank you!
