When was Eminem's mainstream success?

My older brother says Eminem went famous when Marshall Mathers LP came out, and that made the Slim Shady LP go big. And D12's Devil's Night also made him go big, and along with The Eminem Show. He told me after that he wasn't so big after that. His main success was from 2000-2002. He told me in high school kids would wear baggy clothes with bandanna's and hats too be like him, and dye their hair blonde just like him. Is this true?
