KYND Horsehair & Bamboo Toothbrush (4 Pack)

Most toothbrushes use nylon bristles, made from petroleum.

Nylon is plastic.

Every time you brush, microplastic fragments break off and enter your mouth, digestion, and bloodstream.

Twice a day. 365 days a year.

And when you're done, the brush sits in landfill, or the ocean, for 500 years leaching toxins. One billion plastic toothbrushes are thrown away every year in Europe alone.

KYND brushes are fully biodegradable — handle, bristles, and the box it came in.

Fishing lines, tents, bags, rain coats, nuts and bolts... and your toothbrush? All made from nylon.

Good instinct — you're already ahead of most people.

But here's what the bamboo toothbrush industry doesn't tell you: almost every bamboo toothbrush on the market still uses nylon bristles.

The same petroleum-based plastic as a regular toothbrush. The handle composts. The bristles don't — and they're still shedding microplastics into your mouth every single day.

The handle was never the problem. The bristles are.

KYND uses natural horsehair bristles — the original bristle material, used for thousands of years before nylon existed. Zero plastic. Zero compromise.

A little, yes. And that's a good thing.

Because the bristles are 100% woven into the head — no glue, no chemicals holding things in — a few hairs may naturally shed in your first few uses while the bamboo acclimates to your bathroom's humidity. Bamboo expands in heat and humidity, and contracts as it dries.

It settles within a few brushes — then it's smooth sailing.

It's not perfect, but real materials behave like real materials. That's the trade-off for zero plastic, zero toxins, zero shortcuts.

If you're uncomfortable with a few bristles in your mouth, this product is not for you. Sorry!

Still deciding between horsehair and nylon? Read the full comparison — then come back and grab yours.

Sustainably sourced, single piece bamboo handles, ethically sourced & sterilised horse hair bristles, and a small amount of beeswax to coat the handles.

That's it.

Zero plastic. Zero nylon — not even bio-nylon or castor oil-based bristles, which still shed microplastics. Zero BPA, phthalates, or PFAS. No glue, no synthetic coatings, no nonsense.

Fully biodegradable - ready for compost, box and all, when you're done.

We get it!

It sounds unusual because most of us grew up with plastic. But natural hair bristles were the standard for thousands of years before nylon was invented in the 1930s.

Horse hair is naturally flexible, soft on gums, and doesn't shed microplastics.

Once you try it, going back to "polybutylene terephthalate" feels weird.

The right question to ask — and the first one we asked ourselves before we ever placed an order.

100%. KYND horsehair comes from routine grooming — natural mane and tail trimming, plus hair gathered during daily horse care. The hair would shed anyway. The horses don't notice.

We never use hair sourced as a byproduct from animals processed for food or industrial slaughter — full stop. Our supply is cruelty-free, animal-friendly, and verified directly with our supplier. No horse is harmed, restrained, or killed for a KYND brush.

If we couldn't do this kindly, we wouldn't be doing it at all. The brand isn't called KYND by accident.

121°C high-pressure steam for 20 minutes — the same medical autoclave standard used to sterilise surgical instruments. After steam, the bristles get a natural plant-extract soak for added antimicrobial protection.

No silver ions. No synthetic antibacterials. No bleach. No industrial chemicals. Just heat, pressure, and plants.

The result is clean, natural bristles with zero toxic residues.

Each brush lasts 2-3 months, same as any quality toothbrush.

A box of 4 gives you a full year's supply!

Unlike nylon bristles that fray and shed microplastics, natural bristles maintain their integrity right to the end.

Yes. And proudly so!

Every KYND order helps fund tree planting through Ecologi — one of the world’s most trusted climate platforms, with millions of trees planted globally.

We use bamboo because it’s one of the fastest-growing and most renewable materials on Earth. Partnering with Ecologi felt like the natural next step.
