OMG...Great Colour BUT BUT BUT I just don't have the "MY TIME" needed to fluff around with this product.... The mixing of the powders is one thing BUT BUT BUT having to leave it on my hair for FOUR HOURS!!!! Nah. Having long fine frizzy hair, not being able to apply this product via a squirty bottle really got to me too... So, my scores: 5/5 for Colour, georgeous. 1/5 for prep & application ease. Shame really. I can't see me buying it again.
