I was wondering if you could use women's hair spray to make suede leather water resistant or water repellant? I used a commercially made product, (Kiwi), and seems to work well, but the small can of it doesn't go too far, I used as directed, applying light coats and not making it wet. Just wondering if some household product would work as well.

Nope. Stick with the product made for suede unless you want a gooey mess using hair spray.
