Mine has fuzzies between all the bristles. I can pull the hair strands out easily enough but not the fuzzies. I have a friend who sprays scrubbing bubbles on her brushes and lets it sit and soak, but I don't know if that would be damaging to these natural bristle brushes. What do you think? How can I get rid of the fuzzies?

Have you tried using a fine-toothed comb or pick to get the fuzzies out? I think that you can use a mild shampoo in the sink, and swish the brush around in soapy water, rinse and dry (don't soak, that can loosen the glue)

You don't. I had one years ago and I tried washing it with soapy hot water and picking out the fuzz. I had enough of the mess and just bought plastic teeth brushes. I have a wooden teeth brush too. Boar bristles don't make much of a difference for me.

Did you know Sam Goody(not sure of brand) has brushes infused with jojoba oil? I think it is too gimmicky so I never tried it.
