Can't say it's right or not, but it worked.
I took home a nice B.J. Eyre smiling wedge, and an old EverReady boar brush from an antique store. The lovely bride suggested soaking in hot water with lanolin in it. The lanolin did stay separate like oil would, but after about 30 min of soaking, then working the bristles, this ancient boar brush was somewhat pliable. Bristles were pliable, but quite firm. I would describe it on the scratchy side. Another soaking & working of the bristles, and I gave it a spin on Conk soap. I let it sit in hot tap water while showering, with about a tablespoon of hot water soaking on the top of the shave soap (glycerin) It ate the soap for breakfast before it had it's first cup of coffee. Lather was superior to my Conk pure badger brush.
Since then, I got an Omega imported through a Seattle co that looks like their 81230 (a butt ugly brush). The old EverReady is has more backbone & froths up the lather way way better than the Omega.
Now if we could only get a Semogue dealer in the states.
