Can WEN be used on hair that has had a keratin treatment?

My friend loves what WEN is doing for my hair and wants to try it but she has a professional keratin treatment in her hair. She said she can't use shampoos that contain sodium. Do you know if its safe for her to use. I can't find any info about it.

Thanks,
