Yes, you can, but I wouldn’t recommend long-term, intensive use.
While there are some excellent aspects of baking soda, the ingredient has a few negative points too. Baking soda helps remove buildup from commercial shampoo and conditioners. It is also good for absorbing oils and odor.
However, baking soda has a higher pH level than your scalp. This can cause frizz, hair breakage, and hair tangling. The first dry shampoo I made was with baking soda and cocoa powder. I was delighted with it, and I loved how simple yet effective it was. I wasn’t using it weekly, but maybe once every few weeks. If you don’t have any of the other ingredients and need dry shampoo ASAP, you can use baking soda (and cocoa if your hair is darker). However, I would recommend using a baking soda alternative for a long-term solution.
Good baking soda alternatives are bentonite/kaolin clay, arrowroot powder, and cornstarch.
