I love this stuff, Ive had a 1 ltr bottle that has lasted me for ages, bout 3 years.
Instead of getting toner at the salon, I just use this at home and always get the best results, I haven't found another shampoo that compares, using it with the evofabuloso platinum blonde conditioner, it works a treat!
This product always gets rid of my brassiness after a fresh head of highlights
It has a deep purple colour to it and it stays purple once you lather it into your hair, it doesn't go a foamy white like some of the lesser purple shampoos do.
I personally love the smell aswell, its a good classic fudge smell.
Make sure not to leave any on or around the shower when you finish as this will stain.
I used to have almost white blonde hair and would often use the nordic toner but picked this up at shampoo plus as I needed something with more oomph! when I would touch up my roots it would be a pale yellow colour and with 1-2 uses of this it would get my roots matching the rest of my ultra pale hair. it is strong though and the purple can"grab" and stain the hair(usually goes in 1-3 washes). If I were to go blonde again I would use this!
Tips: Never leave it in longer than the recommended time
