I have been using the regular black in the beautiful collection for years since I am allergic to permanent dye. However I saw the one for advanced graying,did a patch test and had no reaction. The day after using it I got bumps on my scalp. A day later my forehead started swelling and the third day my entire face was swollen. I had To go to the doctor. It does cover much better than the regular beautiful collection. What are they putting in the advanced graying solution that's not in the beautiful collection?? Unfortunately I am not going to be able to use this graying solution again.
