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