If your a headblade user shaving in the shower makes it much better experience!!
It's clearly an individual thing! There is one more reason I do it this way....If I shave in the shower there is a pretty good chance of running out of hot water or just plain running out of water!! Ahhhh the woes of small town life!!
I never shave after or in the shower, always b4. That way after a shower my head & face feel so refreashed.
