I dug out an older natural hair brush recently and have used it a few times.
Its a "Progress Vulfix 404 Grosvenor Mixed Badger and Boar Bristle Shaving Brush" which i bought in 2016 and used quite a bit back then.
This last week or so, whenever i used it, it shed a bristle or two each time. I have hung it upside down to dry on a stand each time i used it and always used to do so.
Does the hair loss mean its dying ?
