Why natural hair?
Why natural bristles?
Because the bristles are the only part of a toothbrush that actually touches your teeth — and on almost every bamboo brush on the market, they are still nylon.
Nylon didn't win because it cleaned better
For hundreds of years toothbrushes were bound by hand with natural bristles. Brush-making was a real craft, in Denmark as everywhere else. Then nylon arrived in 1938 — not because it was better for teeth, but because a machine could turn out thousands an hour for a fraction of the cost. It was a manufacturing decision, not a health one.
We haven't invented anything. We simply never switched to plastic.
What a bamboo handle doesn't fix
A bamboo toothbrush with nylon bristles is only plastic-free at the end you hold. The handle composts. The bristles don't — they are the same petroleum-based polymer as on a cheap supermarket brush, and they are what you scrub against your gums twice a day.
Two materials, one promise
Horsehair. A soft, fine fibre cut from the mane. It is silk-soft on tender gums and sensitive teeth, and it is the one we have tested most. The hair is a by-product of the food industry — no animal is killed to make a toothbrush — and it is boiled and sterilised before it goes into the handle.
Plant fibre. Our vegan model. Same handle, same price, and it brushes almost as softly. For anyone who wants to avoid animal products entirely.
Neither contains nylon, glue, dyes or coatings.
The honest drawback
Natural bristles absorb more water than nylon, so they dry more slowly. That is the one thing you need to do differently: rinse well after brushing, shake the water off, and stand the brush bristles-up with air around it — not in a closed travel case or a damp drawer. Do that and it lasts the six to eight weeks it should.
Afterwards
The whole brush can go in the ground. The bamboo handle composts, the bristles break down on their own, and the box is unbleached card with no plastic film. Nothing to pull apart or sort first.
