I purchased my Simpson Colonel back in August and it has been shedding between 5 and 10 hairs each shave, sometimes as much as 20. I got in touch with the supplier and they sent me a link at shaving 101 explaining that it will shed hairs until it breaks in.
I persevered with the brush and this morning while lathering up some MWF in a bowl I noticed no hairs in the dish or the bowl. At last it has stopped shedding. Its taken 3 months to settle down so if anyone is experiencing similar problems, hang in there and it will come good.
