I don't know if this question belongs here, but I've made several hair sticks and sanded them down very smooth, but I'm wondering how to seal them. The ones I've made in the past have gotten dirty and grungy looking (thus the need for new ones!).
I've rubbed them with wax, but I don't know what this would do to hair (?). They look shiny and feel smooth, they don't seem to be leaving it on my hair. I thought polyurethane, but is that going to do something bad to my hair?
Any thoughts or suggestions would be appreciated
