I tried this product because I have used colora henna powder and I thought that I would get the same results. Well I did not, I had a mild reaction. It was not like the allergic reactions I have had in the past with facial swelling and blisters but there was definitely a burning sensation and slight redness. It was only relieved after I used cortisone cream. And to make things worse, it did not color my hair. I would not buy the creme version if you have allergies.
