I am a big fan of purple shampoos, so I was excited to receive a bottle of this to try. Unfortunately I found it was much less effective than my previous brand, Fudge. I like to have my shampoo leave me with that greyish-purple hue, but this is not that type of product. I would notice my hair was slightly less brassy than after my regular, non-purple, shampoo, but the difference wasn't major.
On the plus side the bottle was easy to use and the shampoo smelt lovely - important because some purple shampoos I've tried have smelt horribly strong!
I think this would be a good product if you just want a slightly toning effect for natural blonde tones, but if you're after that really grey tone, this product is not strong enough for what you need.
I love these products, made my hair super soft and shiny at home. Just like leaving the salon. I'm really fussy with shampoo and conditioner bu love these. I don't know if extended my colour or not but I have really fine hair (but a lot of it) and these didn't weigh them down at all.
Can often get these on sale so super good buy.
