Back in May I purchased Rooney S1/S1 Silvertip brush on clearance from a great vendor that I will not name. Started off just loosing 4 or 5 hairs per shave. Then, it got worse. The brush started to loose 10 to 20 hairs with each use. I shampooed and combed the brush. I got about 25 hairs out. Used it a time or two more, it only lost about 5 or 6 hairs per use. I thought it was finally getting better. Then the last two shaves, it lost 25 to 30 hairs on each shave. The vender has since sold his business, but talked to me about it over the phone. I could tell he truly regretted what I was going through. Has anyone ever tried applying epoxy with a needle down into the base of a knot to stabilize the hairs, and stop the shedding? This is something that just came to mind. I love the brush, the backbone, the softness of the tips. It is one heck of a face lathering brush. Or, am I just going to have to pull the defective knot out, and reknot the brush. I would appreciate some advice on this unfortunate situation.
