Too much splaying (with pressing the brush in your face with too much force) may result in the following (good for us brush makers... but not for your brush). A bit pressure is tolerated, but too much is too much...the result is often seen in this donut hole effect, hairs break off and eventually this is what the brush can look like - you may see the first results in smaller hairs in your soap or lather bowl. I think the right word is "moderation" when it comes to applying pressure to get a splay effect.
