I have owned many brushes and have encountered only a few true shedders. Only one of these was a Simpson, a CH2 Best, in fact. That brush was promptly replaced by the manufacturer, no questions asked.
I see a couple different attitudes toward this situation whenever a brush shedding thread appears. Some feel that shedding should never happen, especially in a brush that costs as much as a CH2, and head toward the conclusion that Simpsons brushes aren't worth their time or money.
Others point out the sheer volume of Simpsons sold compared to other brands, the handmade nature of these brushes, and the customer service provided by Simpsons. And they head toward the conclusion that Simpsons are worth their time and money.
Is this a glass is half empty/half full difference? I won't say, but I'm in the second camp. I also wonder if the sheer volume of hair packed into some of their knots influences the occurrence of shedding? Either way, Simpsons provides excellent customer service and stands behind their product. And I prefer their brushes to any of the many others I have used. For me, nothing comes close to the experience of lathering up a Chubby 2.
Please let us know how your new CH2 works out.
I can't speak first hand, but I ordered a custom made brush from someone who seemed to me to be a true artisan craftsman. He was knowledgeable about brushes, and he worked directly with the "badger farmer" where he sourced his hair.
He told me pointedly that he could pack 5g of extra hair into the knot, but that the side effect would be more shedding. He said that the epoxy used to hold the knot together flows through the hairs. If you squeeze the knot to fit more hairs in, it reduces the amount of epoxy holding the knot together.
It seems perfectly logical to me. I had him do it anyway, and the brush I got is great. A couple stray hairs here and there, but thick and luxurious. At a rate of a couple hairs a month, it'll be centuries before it's down to a normal non-packed level.
Simpsons is known for their densely packed knots. It's one of the things that makes a Simpson a Simpson, especially a Chubby. The sell a lot of brushes. It stands to reason that they might have more shedding issues than other vendors. However, if the solution to fix it is to make a Simpson brush not a Simpson, then is that really what you'd want?
I'm not saying that the level of shedding demonstrated in this thread is acceptable. Clearly it is not, and the retailer and manufacturer knew that, and took care of it. There are most definitely people who freak out when even a single hair is shed, especially when they pay a lot of money for a brush.
So that, plus the volume of brushes, plus the handmade nature of each brush, plus the density of the brushes leads me to believe that maybe a little more shedding, within reason, is to be expected from Simpson brushes, but that it's not something to be terribly worried about, unless you are having massive sheddage.
