Hep c cause Cirrhosis stage 4grade1 treatment cured from hep c, Can Cirrhosis still progress and keep scarring the liver after been clear from hep c?

Yes. Unfortunately cirrhosis is an irreversible process and some of the inflammatory activity that leads to scarring of the liver may proceed in absence of the virus (autoimmune mechanism). However, getting rid of the virus at least removes the initial or major cause of inflammation and thus may slow down the entire process.
