Will Mason Pearson’s nylon bristles get softer over time?

I recently got a mixed bristle brush but I feel like the nylon bristles are a bit too stiff/pointy on my scalp. I wanted this brush because i wanted a quality item that lasts a long time and other dupes’ bristles fall off quickly or are more abrasive to your scalp. Should I still keep this brush and hope it gets better or should I sell it?
