well to remove hair you should use a tight tooth comb, to actually clean it, take it in the shower with you and shampoo it and condition it. sounds nuts but the shampoo will clean it and the conditioner will help your hair with shine when you brush it..What is the best way to clean a hard bristle hair brush?
boil it for 25 minutes.
Hot water and a comb. If that doesn't work go to dollar tree and get a nwew one for a dollar.
hot water
Scrub it with a comb in hot soapy water.


Hot water...not boiling. Too hot and


the brush will become brittle.


Then rinse it with hot vinegar water.


Then with hot clear water.


It will be clean as a whistle...........
