Washing foundation,fluidline and concealer brushes weekly,too often?

[sugarting]

I wash my benefit foundation brush, mac 209 and laura mercier concealer brushes weekly, coz they just get so dirty! especially the 209, it dries and gets so hard after each use and i wish i could wash it everyday! but my only concern is that is washing your brushes weekly too often? will it damage my brushes? i really need your professional opinions!
