Great Product but READ the fine lines
I was hesitant to purchase this as I have read it doesn't work for everyone. Thankfully this product warned that some might be allergic so to try a test for 24hrs. Luckily I wasn't allergic to the chemicals. The overall results were perfect after my first use and last more than a week. the longer you leave it the darker the color gets. The manual is easy to understand and product easy to use.
