Definitely brings out some natural highlights

When I first used this I didn't realise how blue it would actually be! In the process made quite a mess, I would recommend using disposable gloves if possible to prevent blue/purple staining on hands. That would be my only con, whereas the pro's were quite interesting and didn't realise I actually had hidden highlights in my brown hair. Would definitely recommend for brunettes just don't forget to wear gloves.

Unusual but good

Very unusual and I have never used shampoo that was blue but it is really nice actually and makes my hair very soft. I would not use it while having a bath tho :) but I would recomend it.

Nice product ...

Nice product! Smells lovely! However I’m not sure if I noticed a difference if my hair is a different colour... but will still continue to use as I love the smell!

New crush

The shampoo smells lovely, left my hair feeling clean and soft, it has toned down my brass tones in my hair, but feel this will improve the more times I use it. the only downside is the blue shampoo can be quite messy and you need to be careful with your surroundings and your hands to prevent staining.

efficient colour reviving shampoo

I tested this shampoo together with conditioner for about 1,5 week and I really liked how it improved my brown hair. What I liked the most was how well it moisturized and nourished my hair and refreshed its colour. This shampoo is also pleasant to use, easily washes out and leaves my hair bouncy and shiny. Brassy tones were really softer.

Blue!!

When I first used the shampoo, I wasn’t expecting such a vibrant blue, I had a slight panic when I noticed a slight tinge of blue to my hands when I used the shampoo! My hair feels super clean, and super soft (especially pairing with the conditioner) I would definitely purchase in the future!

Good shampoo

Well first of all good parts:
*it does clean the hair without drying them out
*it smells amazing, really love the smell hovewer not sure if it's completely healthy for hair.
*like the package, seems easy to use and looks nice.

Now as why i gave 4 stars, it says it shouldn't stain, but it does a bit, so i would recommend washing hands as soon as you put shampoo over the hair. Also, it's probably not suiting my hair colour as well, didn't really gave a cool tone after first time. I usually use purple shampoo, but thought give a try for blue one. But if you have lighter hair i would recommended sticking to violet :) my original hair colour is quite light brown, or dark blonde, which is bleached.

Amazing smell and smoothness

I loved this product because of its smell and how it leaves my hair: super soft and smooth! The blue pigments help your hair to reduce orange/yellow tones to give them a beautiful brightness.
Would recommend for brunettes, not for blonde hair!
Would buy them again!
