So the good points first! It's an excellent price, it doesnt smell too bad, there is a decent amount of product which easily covers my shoulder length hair, and the best bit.. it absolutely and totally covers my grey hair.
The not so fab is its longevity. I have used this product in dark brown and red shades. The dark brown shades work great and last until my roots need done, the red unfortunately, not so great. When I used a bright red over pre lightened hair it fell out really quickly, it looked a washy corally red after a week. The dark red over darker hair was more successful but still not great, it definitely lost vibrancy after a few washes and needed redone after 4 weeks.
