When I comb hair on the scalp, the hair gets pushed into the mesh leaving "bald spots".

  • I used puff to bring hair above the mesh and stand straight up but issue repeats whenever I comb the hair, even if I do not comb directly against the scalp.
  • I tried flipping the normals of the problem areas but it just deforms the mesh.
  • I selected both "Free Edit" and "Disconnect All" and tried a redo on separate occasions and have the same problem.
  • I moved my particle edit up and down in my modifier stack.
  • I made sure I am not in Particle Edit when rendering.
  • I lessened the strength of the comb tool to .299
  • I changed the Children from Interpolated to Simple

I tried searching the net and this forum for similar issues. It seems this has been a problem for some years but most answers are guesses (which lead me to the corrective issues above).

Does anyone know why this happens and/or how to fix it? Thanks in advance.

I believe that this is because of two reasons.

  1. You'll want to increase the Draw Path Steps (should match particle Steps in particle settings for view port hair to match rendered results) to add more detail while you comb. Draw Path Steps is found in the Tools Panel while in Particle Edit* mode.
  2. Make sure that Deflect Emitter is on in the tool panel while in particle edit mode and set it where the hair no longer collides.

You can't do anything about it. It was coded to be like that.

Put cursor in the middle of the head, uncheck "keep roots", select roots, scale roots to nearly the cursor. Check "keep roots". Comb hairs as you want them to be. They will penetrate surface of course, leaving bald spots. Uncheck "keep roots". Select roots again and move them up (towards head's top). It helped me, at least.
