Hi. I shave my head & I've found that, no matter what post shave product I use, or if i dont use one, I get a ridiculously oily scalp a few hours later. I haven't tried too many options but have tried perfumed & unperfumed aftershaves, balms, isocol, and proraso preshave cream. I've also tried showering with soaps, body washes & just water. Whatever I do or don't do, my head is slimy like old ham by lunchtime. Any advice to prevent further embarrassment would be greatly appreciated.
