Your Bag
The Bristle Nobody Thought To Question
Almost every bamboo toothbrush has a secret: the bristles are still nylon. The handle composts, but the part that actually touches your mouth doesn't. These heads are different. The bristles are 100% natural horsehair, the same keratin family as your own hair, set into a bamboo body. Nothing synthetic where it touches you.
Natural Bristles, Real Cleaning Power
Everything a replacement head should do, made from materials you can actually pronounce.
Made For Your Briut Sonic
Same two-minute routine, better materials. The snap-on fit works with the handle you already own, so the whole upgrade takes about ten seconds.
What Owners Tell Us After Switching
Gentle On Gums, Serious About Plaque
Horsehair is the softer of the two natural bristle materials, closer to a soft nylon than a stiff boar brush. It flexes along the gumline instead of scraping it. And because your Sonic handle does the work at 40,000 vibrations a minute, the cleaning comes from the motion, not from how hard the bristle scrubs.
One Less Plastic Thing In Your Bathroom
You replace brush heads every three months, forever. It's the most-replaced item in your bathroom. Make that swap a bamboo-and-horsehair one, and that steady little stream of thrown-away plastic quietly ends. Ten seconds to snap on, and the routine stays exactly the same.
Good To Know Before You Switch
Straight answers about fit, materials, and care.
Will these fit my Briut Sonic handle?
Yes. They're made for the Briut Bamboo Sonic and Sonic Series handles. They press onto the metal shaft and seat with a firm click. They won't fit other brands.
How often should I replace a head?
Every 2 to 3 months, same as any brush head, or sooner if the bristles start to splay. One box of three covers roughly nine months.
Is horsehair vegan?
No. Horsehair is an animal-derived material, sourced ethically as a byproduct, never from animals raised or harmed for bristles. If you prefer a plant-based option, our standard bamboo heads fit the same handle.
Does it clean as well as nylon?
Yes. With a sonic brush, the cleaning comes from the vibration and your technique, not bristle stiffness. Horsehair flexes along the gumline and lifts everyday plaque through the same two-minute routine.
How do I care for natural bristles?
Rinse well after brushing and stand the head upright to dry with some airflow. A few loose hairs in the first days are normal for the material and settle quickly.
