Review (3/5): It washes off after 5 washes.
It was easy to use and worked perfectly for 3 weeks. I originally bought this to cover up my gray hair and for the first three weeks my hair looked great! However, I’ve noticed that ALL my gray has came back. So disappointing! I have a very dry scalp so I wash my hair every 2-3 days, so imagine if you washed your hair everyday- it would’ve probably washed off in 1-2 weeks!
