Question: can you put dry shampoo in hand luggage?
Answer: YES, you can bring dry shampoo on a plane. ... So if you want to bring dry shampoo in your carry on, it has to be 3.4 oz or less. Canisters that are larger than 3.4 oz must go in checked luggage. And yes, even if you prefer an aerosol spray, you can still bring it in your checked or carry on luggage.
