…if there’s a difference in deodorant efficacy between shaved and unshaved armpits. I could see it going either way, although I lean towards the theory that shaved + deodorant is perhaps slightly more effective. Why?
Less stinky because fewer hairs for sweat and stink bacteria to adhere to
Less stinky because deodorant goes directly onto skin
More stinky because less area for deodorant to stick
Less stinky because more area for deodorant to stick (all those hairs)
More stinky because hair insulates skin from getting directly deodorized
More stinky because more hairs to sweat and stink bacteria to adhere to
