Your First Shaving Brush
Synthetic, boar, or badger, what each is, what they cost, and which one to start with.
What a brush actually does
The brush has two jobs: load soap from the puck onto the bristles, and whip air + water into that soap until you have a thick lather. It also distributes the lather over your face evenly and lifts the beard for the razor. Without a brush, you’re just smearing soap.
Three types
Synthetic. Modern fibers (often called “plissoft” or “tuxedo”) that mimic badger. Cheap, fast-drying, vegan, easy to clean. The default first brush, and what most veteran wet shavers reach for on weekday mornings. The fiber tech got really good around 2018; pre-2015 synthetics felt like a paint brush, modern ones don’t.
Boar. Stiff bristles from boar hair. Cheap. Needs a 2-3 week break-in period during which it sheds and feels rough, after that, it splits at the tips and gets soft, in a face-scrubbing way that some people love. Good if you like exfoliation; skip if you have sensitive skin.
Badger. Soft, water-retaining, dense. Tiers go from “pure” (cheapest) → “best” → “silvertip” (most expensive). A silvertip brush is a beautiful object and feels like a small cloud. It’s also $80-300 and not better at making lather than a $25 synthetic.
Recommendation
Buy a synthetic. Specifically:
- TWSS Black Synthetic with G5 Knot (~$21 USD), TWSS’s house synthetic. Minimal handle, soft-tipped G5 knot, hard to beat at the price. The default first brush.
- Noble Otter 26mm Synthetic (~$25 USD), Slightly larger 26mm knot from a popular artisan brand. Builds dense lather quickly. The middle pick.
- TWSS Faux Horn Synthetic with G7 Knot (~$23 USD), Step-up TWSS-house brush with a denser G7 knot for shavers who want heavier lather. Same handle ergonomics as the Black G5; richer load.
A 22-26mm knot is the sweet spot. Smaller is fine but builds less lather; bigger gets unwieldy.
Why not start with badger?
Badger isn’t worse, it’s just more expensive and harder to evaluate. A bad badger brush is worse than a good synthetic, and at $30 you can’t tell which you’re buying. After you’ve used a synthetic for a few months, your hands will know what you like, and a $50-80 “best badger” makes a lot more sense.
Brush care
- Rinse thoroughly after every shave, work water through to the base of the knot, soap residue at the base rots fibers.
- Hang it bristles-down in a stand or just lean it against a wall. This lets water drip out instead of pooling at the glue plug.
- Don’t dunk it in boiling water. Hot tap water is fine. Boiling water softens the glue holding the knot in.
- Rotate two brushes if you can. Lets each one fully dry between uses. Two cheap brushes outlast one expensive brush kept on a daily duty cycle.
Frequently asked questions
What does a shaving brush actually do?
A brush has two jobs: it loads soap off the puck onto the bristles, and it whips air and water into that soap until it becomes a thick lather. It also spreads the lather evenly and lifts the beard so the razor can cut it. Without a brush you are only smearing soap around.
Should my first brush be synthetic, boar, or badger?
Synthetic. Modern synthetic fibres are cheap, dry fast, clean easily and are what most veteran wet shavers reach for on a weekday morning. Boar needs a two to three week break-in during which it sheds and feels rough. Badger is soft and dense but expensive and hard to judge at the low end.
Is an expensive badger brush better than a cheap synthetic?
Not at making lather. A silvertip badger brush is a beautiful object and feels like a small cloud, but at 80 to 300 dollars it does not build better lather than a 25 dollar synthetic. Badger makes more sense once you have used a synthetic for a few months and your hands know what you like.
How do I look after a shaving brush?
Rinse it thoroughly after every shave, working water all the way down to the base of the knot, because soap residue at the base rots the fibres. Hang it bristles-down so water drips out instead of pooling at the glue plug. Never use boiling water, which softens that glue. If you can, rotate two brushes so each dries fully between uses.
