Will senslip smooth out my head?

I'm not sure what senslip is, but it's my understanding that anything that imitates the natural action of your foreskin will cause your head (glans) to return to it's natural state to some degree. Your stretched foreskin will not have the capacity to secrete the oils that your original foreskin did, and it won't have the specialized structures that were there originally, but the process of protecting your glans will reduce its reaction of thickening and drying out to protect itself, so the skin will become smoother, thinner, and some of the sensitivity will return.
