My grandmother was a hair dresser, now she has been a pensioner for a long time but still she is the one who cuts my hair. I've never been to any other hair dresser in my life. Ever since I remember every time we visit our grandparents my grandmom has had a clean hair brush for us to use after the sauna and we visit there often, especially we did when we were kids. She seems to still have pride in her old profession which I highly appreciate.
My grandmother always used natural brushes and so do everyone else in my family. I have never learned to like the plastic or metal brushes, they hurt my scalp and tangle on the hair. I don't clean my hair brushes very often, at least not as often as my grandmom, but when I do clean them I clean them just as my grandmom does.
All hair is removed from the brushes using a thick comb. Then the brushes are washed, to do that I run luke warm water in a sink and add to the water some shampoo, soap or other mild cleaning product. I let the brushes sit in the soapy water for a minute, not longer because the wood might expand from too much soaking. Then, since I have two hair brushes, I brush them against each other to open the space between the bristles and get the gunk out. If you only have one hair brush, use a comb or hand to do that. Then I just rinse the hair brushes clean and let then air dry.
Also my grandmother always says that hundred strokes (or is it sweeps?) a day with a hair brush keeps hair looking healthy and clean. Oh and that everyone should eat chaulk, that according to her keeps hair looking good. I obviously don't do the hundred strokes a day, I only brush my hair before and after I wash it. I brush before with the red hair brush so my hair won't clog the drain and after with the wood toned one so the hair does not end up all shaggy when it's dry. And I don't eat chaulk either. But don't tell my grandmom.
