Is it bad to wash your hair by shampoos frequently?

if you have dry hair you shouldn't wash your hair everyday because shampooing strips your hair of natural oils, and so your hair gets more dried out and dirtier actually. You should wash it every other day. And about the gray hair thing...that's just a myth.

I wash and condition my hair everyday when I have a shower and it makes me feel great for the rest of the day. When I was young and at school people tended to wash their less frequently. I remember a friend of mine at school , when we would be teenagers, complaining how greasy her hair was between washes. I said why not wash it more often - believe it or not she had not thought of it and neither had I until then but she thought it was a great idea and her hair always looked great after that. Before it would look nice for a couple of days and then it would look greasy. It is funny how the answer to a problem can be so simple and under our noses but we can't always see it ourselves. (It doesn't make your hair greyer quicker)
