Homemade Johnson’s No More Bedhead spray

I have boys with thick hair that needs quick taming in the morning. Plain water isn’t controlling it. I sometimes use No More Bedhead or No More Tangles, but it’s too costly anymore. I wondered if anyone had a recipe for something I can spray on their hair that won’t gunk it down too much. I tried adding a little conditioner to the water, but it makes their hair dirty very quickly, and getting them in the bath every other day is challenge enough! Thank you!
