Question about SHIMMER LIGHTS shampoo and conditioner?

so iv just become blonde.. and im planning on using shimmer lights. but i have a few brown low lights under some of my blonde. is it okay if the shampoo and conditioner gets on the brown??Question about SHIMMER LIGHTS shampoo and conditioner?
Yes. My hair is bleached on the top and it is dark brown underneath and it only brightens my blonde. It won't do anything to the brown because it is made only to work on blonde. But be careful because one time I left it in too long and it turned my blonde purpleish-greyish.





Hope this helps =)
