Marines, skinheads and head-lice victims all agree: There's nothing like having your head shaved. The warm lather, the feel of a razor (preferably a straight razor) scraping over your scalp, the sting of the post-shave tonic on your freshly shaved pate — it's the tonsorial equivalent of a deep-tissue massage. For those of us who prefer to leave an inch-wide, inch-high strip straight down the middle, nobody etches a finer Mohawk than Ambrose Cardenas at Joe Lee's Barber Shop downtown. Shortly after we moved to Houston, we wandered into Joe Lee's wondering if anyone in town would be able to touch up our 'Hawk; the soft-spoken, laid-back Cardenas didn't bat an eye and told us to have a seat. We've been going ever since, and only wish we could figure out a way to make our hair grow faster.
