I have had this kabuki brush since 2014 and I still use it regularly for buffing setting powder into my face.
It is densely packed and feels lush and soothing against my face. In the first year, it didn't shed at all. However, recently, some of the brush hairs have begun fall out during washing. That said, it's probably because of its age and nothing concerning since it is so dense in the first place.
I love this brush and it's definitely a high quality staple in your kit. 10/10 would recommend.
