have you tried using dry shampoo? when i first heard of it, i instantly said i will never use such thing but i got curious and tried it. and i've been using it since then. don't get me wrong! i do have a shower. i use it in between washing to give my hair a rest coz dry shampoo is talc base. it actually gives your hair extra volume too.
more and more girls are using it now. the sales of dry shampoo has gone up a lot recently. even big salon chain are making their own dry shampoo product already!
