Not the best
I bought this product based on the reviews... I had to use it (3) times, In the SAME day, to get any kind of results — First try, The directions said to leave it on for 3-5 mins. Nothing! Second try, YouTube suggested 10 mins. Still nothing! Third attempt, I left it on for an hour, and finally got a lightly faded tint. Very disappointed. I used it again the next day (a 4th time), left it on for 30mins and FINALLY got some color. Not nearly as simple as it seemed/should have been, but the application was easy and the product arrived quickly.
