Can you mix half a bottle of water into shampoo and use it for several weeks?
I have a sulphur shamoo I only use on my scalp because I found my hair is healthier if I only wash my scalp. When I wash my hair fully I have a different shampoo. I am running low but have learned to use a small concentration on just my scalp. Can I put water in it and use it for several weeks or will this make it go bad?

It wouldn’t be as effective. It’s like adding half a bottle of water to your beer and still expect it to be the same.
