Has a lot of blue pigment and great for brassy blonds!

**Warning** Use gloves, this will tint your hands right away!

I have tried many purple/blue shampoos and conditioners from prestige brands to store brands.
This one is one of the most pigmented I have tried. This mask has a lot of blue pigment rather than purple, so it works better for brassy tones rather than yellow tones. I think if your hair is overly yellow, this mask might give off a a bluish green shade like it did to some of my strands. The shampoo though is more of a purple base and works better for my yellow orange hair. This is not really moisturizing to be honest, so best to use conditioner or another mask after using this. I usually put this mask on damp hair and let it sit for 10 min or more. With the shampoo version I also let it sit in as I think it has even more pigment.
The Ice Cream brand also has a Light Blue Mask version, which contains more blue based pigment and is better for very light orange hair or ice blond hair.

Just an FYI, if you have extremely orange roots/hair, no amount of purple shampoo or conditioners will cancel out your orange, you will need to lighten your hair again, these products don't lift the hair level, so keep that in mind when you realize your hair isn't much different.

Hope this review helps :)
