Delete Loops uses the curvature turned off then the new curvature close to the original.
As you add volume to geometry to extreme measures, the you wishsimply hold new clay the actual consistency of the material remains exactly. This means that areas that already had nice polygon distribution will keep them even after is evenly distributed across the.
The same problem exists in ears too. Dynamesh will fuse geometry, Zremesher will not. You will need to switch to a traditional multi-subdivision level workflow in order to keep adding fine detail. DynaMesh accomplishes the same thing, maintaining the uniform resolution and polygon distribution of your mesh. This is very unlike traditional sculpting methods which result in stretched polys if you push the surface too far � something that hampers your ability to do anything more with the surface in those areas.
