Currently the brush hairs are still made out of BPA-free nylon. We’re busy finding a green alternative for this. We recommend using a pincer to take out the hairs and then simply throw the toothbrush in the green bin or come up with something creative to reuse it for.
The reason why we are still using nylon hairs is because so far the only alternative are boar hairs. We wan’t to keep our products animal free so we’ve chosen to stick with nylon hairs for the time being.
