|Yellow blond before, cool blond after.|
It's a colored conditioner with a pretty potent purple pigment in it. Kind of like Manic Panic's Virgin Snow dye the lilac toned neutralize the brassy yellows for a nice cool blonde. I've used a few different conditioners like this one such as John Freda's, but liked this best because it made my hair softer, and seems to have quite a bit more pigment in it.
I was originally put off by it because it is a little pricey, but the nice thing I found is because it's so strong I don't need to use it every day, in fact I tend to only use it once or maybe twice a week tops, usually if I'm taking a long shower, so one bottle usually lasts me about 2 months or there about.
Yesterday I pulled out some old hair pieces I made a while back, and used the Blue Malva to tone one of the pieces to match my current hair (or a bit closer, the wefts I used were darker than my current hair), so you can see the difference! (both pieces are from the same weft only one hasn't been conditioned, the other has) I don't do a lot of product reviews but after seeing my 2 hair pieces side by side I thought it might be useful for any other blondes out the fighting the brass!
So there you go, for all the people who have asked in the past how i get my hair the color it usually is, that's how!
