Have you noticed your BBS SE/inj shaves lasting longer (hand feel-wise) than your DE BBS shaves? I've been suspecting this for awhile and so set out to prove it to myself yesterday. Yes indeedy, my DE shave yesterday (fully BBS) was considerably rough early this morning. On average, I'd say my SE shaves stay smoother for about 6 hours longer than my DE shaves, with both starting out BBS. I can't begin to explain it as it makes no sense at all, but it's a fact! Any ideas why?
