OK

pu2. I heard that using dry shampoo can last for a long time, but dry shampoo doesn't use water at all, but it's kind of uncomfortable

OK

pu3. @2 Does it work with dry shampoo? It's baking soda instead of dry shampoo. Do you mean I can wash it with baking soda?

OK

pu4. It's not good to keep using dry shampoo. I don't know if you wash your hair without water when you need it, but I heard that if you keep using it, you can get hair loss
