Vickie, Shaving can result in those little whiteheads. I don’t know what causes them to happen…a little nick of the skin on a hair that’s growing 45 degrees (or less) out of the skin, maybe? I also don’t know why they sometimes occur with electrolysis…my guess would be several things. Too much current on moist skin; skin wasn’t clean enough; introduction of bacteria immediately after treatment - there could be other reasons.
Regarding: Prestige Electrolysis and Texas Electrolysis - I have had excellent experiences with both. Most (but not all) of my Texas purchases have been at conventions, but I order from Prestige almost monthly, and my one return was no problem - it was taken care of immediately.
