How a Hot-Towel Shave Actually Works (And Why It Takes 40 Minutes)

A short field guide to the straight-razor shave at Waterloo Barbershop — what the towels do, why we lather twice, and why forty minutes is the point.

§ Journal · April 20, 2026

A first-time hot-towel shave can feel mysterious. The barber moves through it as if it were a single motion — towel, lather, blade, towel, balm — but each step is doing real work, and a forty-minute shave is the only kind that does the work properly.

Here’s what actually happens.

The first towel

The shave starts with a hot, lemon-oil-scented towel laid across the face for about a minute. It looks like comfort, and it is — but it is also the first piece of physical work in the shave: the heat softens the keratin on the surface of each beard hair, and the moisture lifts the cuticle. A shaved hair that is hot and damp cuts cleanly and at a slightly steeper angle, which is why a properly-towelled face produces a closer shave than soap on dry skin ever can.

The first lather

Between the first and second towels, we whip up a lather in a wooden bowl with a badger-hair brush. Two things matter here. The first is temperature: the brush sits in hot water while we work the towel, so the lather hits the face warm. The second is the direction of the brush — we apply lather in small circles against the direction of the beard’s growth, which lifts hairs away from the skin and brings them to standing. Both are why we don’t use a tube of cream from a drawer.

Two passes, with the grain and across it

A real shave is two passes, never one. The first pass is with the beard’s grain, and clears the bulk. The second pass is across the grain — never against — and takes the rest. A pass against the grain is what gives men ingrown hairs, and we do not do it. If a patron asks for a “BBS” shave (the term comes from the wet-shave forums and means baby-bottom-smooth), we’ll have a conversation; for most men, two well-executed passes are smoother than three rough ones.

The second towel

A cool, witch-hazel-soaked towel finishes the shave. Where the first towel was about lifting the beard, this one is about closing the skin and tightening the pores. If you’ve nicked yourself shaving at home, you’ll have noticed it stops bleeding faster on a cold cloth than a warm one — the second towel is doing the same job at scale.

Why forty minutes

A forty-minute shave is sometimes mistaken for a slow shave. It isn’t. Each step is short — five to seven minutes — and the time is mostly in the rest between them: the moment the lather sits before the blade, the moment the towel sits before the lather. Hurrying any of these steps shaves you twenty seconds off the total and costs you a closer shave. The right number of minutes is the number of minutes the work asks for. At Waterloo, that number is forty.

How to book

The Hot-Towel Shave is $38. It’s by appointment only — the chair is too quiet for a walk-in. Jessica works the chair and the razor.
