Yes it really works in 5 minutes; hard to find

Purchased this to touch up my grey roots. It appealed to me because I can mix just the amount I need for that application. The remainder is kept for future touch ups.
I was shocked at how it covered my roots in just 5 minutes. In fact it was darker than my typical colour which is left on more than half an hour.

PROs
- mix just the amount you need for one application
- works in just 5 minutes Of application time

CONs
- my hair is light brown and even their lightest colour was too dark. Wish they offered other colours
- difficult to find in Ontario, Canada I found it at Superstore
