Hello, at the moment I have platinum hair. I really don't like it me. I'm either going to go back to brown or try to get it to a light more natural blonde instead. Brown is a last resort and I'd rather just darken the blonde. How can I darken up my platinum hair to a more natural blonde? Any products you guys can suggest would be great. Right now I have Redken 9n and 9v on my hair. Thanks!
