How often do i need to replace this brush?
I feel that it doesn't give me the same coverage after a while. I do wash the brush with the bare minerals brush shampoo.
So, I believe that it all depends on the type of brush, how you take care of it, and how long you have had it. It sounds like you take care of your brushes, just make sure to be gentle when washing them. I think Leslie has a video on how it should be done. It sounds like you need a new brush. If it is not giving you the same coverage it used to maybe it is time for another. Hope this is helpful! Good luck!
