Hello My bf and I found a strange thick whisker like hair in his back it was so thick and white that we thought it was a sponge we use fir scrubbing in the shower. Only a couple of mm's were showin and with twizzers pulling it out in was about 1.5-2cm's long. We thought that it was a one time thing but then again we found it in the same spot about a month later and we are wondering what it is. Please let us know

thanks
