Q: Disposable or washable

If used gently, you could wipe down to reuse again. But you would lose some of the stickiness from the adhesive tape that attaches it to the forehead. These are made to be for disposable use. It covers the eyes, but not the nose fully.

Q: Are they waterproof? Can water or product seep get through the adhesive part at top. ? Thank you.

Water & product can easily reach the adhesive. But it is a very sticky adhesive. If you're just needing to block a little bit of water from dampening the hair, I think it would be fine.
