Review (3/5): Doesn't last too long
This product was easy to apply and did have good results. I used them on my brows because I am so fed up with paying for it to be done poorly at the salons! The only bad part was this only lasted maybe 4 days, and I only showered 2 of those days :( I wish it would last longer, but honestly when I get them done at the salon it's probably about the same length for me. I naturally have black hair (very thin hairs on my brows where they look barely there) but have it highlighted and got this in Dark Brown and it was perfect. Even though it doesn't last too long, you get a lot more for your money compared to getting them done at the salon.
Another plus is that you only need to leave this on for 2-3 mins. When I go to the salon, they seem to leave it on longer, so I do like not needing to have this sit on my skin for a long time and still yield the same results. I don't think letting this sit longer would make it last any longer.
