But it can be very bad for your hair. Washing it so much everyday can dry it out, and cause hair loss. 你 should leave at least a one 或者 two 日 gap between washes.
^ It's good to care about your hair, but doing that too much can really hurt it. 你 have to think about that. And I doubt it would get too dirty if 你 left it alone for a day. :P
It's actually not good for your hair 或者 scalp to be washed that frequently regardless of what type of hair 你 have. It can seriously damage it, 由 drying it out too much. Shampoo washes away the natural oils in your scalp and if you're washing it up to 5 times a 日 you're not allowing your scalp to produce it's natural oils at all.
If 你 have severely overactive oil glands in your scalp, then I suppose it's fine.
If not, then just try using a dry shampoo, 你 can find some anywhere. They allow 你 to clean out the oils without using water, which sucks out all the moisture.
