Is a bamboo toothbrush vegan?
Usually, yes — most bamboo toothbrushes use nylon bristles, and nylon is synthetic, so they’re vegan. Ours is the exception: our bristles are horse hair, an animal product, so our brush is not vegan. The catch worth knowing either way: vegan nylon bristles are plastic.

Why a seller of a non-vegan brush is writing this page
Because almost nobody else will write it straight. Brands with nylon bristles say “vegan” and stay quiet about plastic; brands with animal bristles say “natural” and stay quiet about the animal. We sell a horse hair brush, so we have no way to win this page — which is exactly what makes it worth writing honestly. If you’re vegan, by the end you’ll know precisely what to buy, and it won’t be ours. That’s fine with us.
Where the vegan question actually lives: the bristles
A bamboo handle is a grass stem — plant matter, vegan by any definition. The question is decided at the bristle bed. Most toothbrush bristles, bamboo brushes included, are nylon: a synthetic polymer made from petrochemicals, with no animal input. Vegan, yes — and also a plastic, which surprises people who bought bamboo to get away from plastic.
The minority of brushes with natural bristles use animal hair — boar bristle mostly, horse hair in a few, ours among them. Those are animal products, and no honest label can call them vegan.
The map, in one table
| Bristle | Vegan? | Plastic? | The honest catch |
|---|---|---|---|
| Nylon (most bamboo brushes) | Yes | Yes | Worn bristles shed microplastic fragments; pull them out before composting the handle. |
| “Bio-based” / castor-oil nylon | Yes | Yes | Plant-derived feedstock, but the result is still nylon — a plastic that doesn’t compost. |
| Boar bristle | No | No | An animal product, generally a by-product of the meat industry; firmer feel than most people expect. |
| Horse hair (our brush) | No | No | An animal product — collected as a grooming by-product, no animal harmed, but that makes it ethical to our standard, not vegan. |
Ours, plainly
Our bristles are horse hair. The hair is collected during routine grooming — care horses need anyway — and no animal is farmed or harmed for it. We think that’s a genuinely defensible way to make a plastic-free bristle. And none of it makes the brush vegan: a by-product of an animal is still an animal product. Both things are true, and we’d rather hold them both in front of you than pick the convenient one.
If you’re vegan, here’s your brush
A bamboo handle with soft, fine nylon bristles. It avoids the plastic handle, it involves no animal, and dentists’ advice — soft bristles, light pressure, replaced on time — is fully available in that format. Read the label rather than the leaves on the box: “natural bristle” means animal hair, and “biodegradable bristles” claims rarely survive checking. The one trade-off to accept with open eyes is the plastic in the bristle bed — snap the head off or pull the bristles before the handle goes in the compost.
The short version
- Most bamboo toothbrushes are vegan — their bristles are nylon, which is synthetic.
- Nylon’s trade-off: it is a plastic, and worn bristles shed microplastic fragments.
- Natural-bristle brushes (boar, horse hair) are not vegan. Ours is one of them, and we say so plainly.
- The vegan pick: bamboo handle, soft fine nylon bristles, label checked.
- Animal products or plastic — each brush picks one. Choose the line that matters most to you, knowingly.
Common questions
01Are bamboo toothbrushes vegan?
Usually, yes. Most bamboo toothbrushes pair a bamboo handle with nylon bristles, and nylon is a synthetic made from petrochemicals — no animal involved. The exceptions are natural-bristle brushes like ours, which use boar or horse hair: those are animal products and are not vegan.
02Are toothbrush bristles vegan?
Nylon bristles are vegan — nylon is a synthetic polymer, which is also why it's a plastic. Natural bristles are not: boar bristle and horse hair are both animal fibres. If a brush is marketed as 'natural bristle', it is an animal product; if the bristles are nylon, it's vegan but the bristles are plastic.
03Is The BARE Brush vegan?
No. Our bristles are horse hair, which is an animal product, so our brush is not vegan — and we'd rather say that in the first sentence than let 'natural' imply otherwise. The hair is collected overseas as a by-product of routine grooming and no animal is harmed for it, but a by-product of an animal is still an animal product.
04What's the best vegan toothbrush?
A bamboo-handled brush with soft, fine nylon bristles covers the vegan requirement while avoiding a plastic handle. Check the label rather than the vibe: 'natural bristle' means animal hair, and bristle claims like 'biodegradable nylon' deserve scepticism. The trade-off to accept knowingly is that nylon bristles are plastic and worn bristles shed microplastic fragments.
05Is bamboo itself vegan?
Yes — bamboo is a grass, and a plain bamboo handle is a plant product. The vegan question in a toothbrush lives almost entirely in the bristles, which is why the same handle can carry a vegan brush (nylon) or a non-vegan one (boar or horse hair).
