Aveda blue malva shampoo is a product I've been using for about a year, now. My girlfriend showed up with it, and although I balked at her spending $25 on "shampoo" when I was used to spending just a few dollars on shampoo, boy, am I glad she did.
I'm at the age where the greys and silvers are showing up more and more throughout my dirty blonde hair. Aveda's blue malva shampoo has been perfect for making my greys more silvery, and my silvers more silver-which I suddenly wanted to experiment doing, once she showed up with this particular shampoo.
Also, it enhances my blonde hair, since it's been shown, not only industry-wide, but now, personally as well, that one of the ingredients in it, coneflower, intensifies whatever your natural color may be-not just blonde hair.
Additionally, if you want to neutralize the brassiness of your blonde hair, not that there's anything wrong with brassiness in blonde hair, then Aveda's blue malva works to that end as well.
Believe me, you, this review doesn't even begin to do the product justice, since I haven't even begun to get into the organic herbs and natural ingredients which are in it, and all of the other benefits of using it. This is a product that certainly falls into the category "you get what you pay for!" It's all I use now.
So, if you want to make your greys more silvery, and your blonde, or any color hair for that matter, more intense, then Aveda blue malva shampoo is the one to use.
