Health, as I said, I will IY”H discuss the Sugya of Sheitels (The Matirim and Osrim) in great length. We will see that those who permitted, permitted even skin tops etc. and those who forbade, prohibited even tapered synthetic wigs with an extra covering for that matter. The issue of long and bouncy wigs has nothing to do with the Halachos of Sheitels rather with Tznius (same issue with hair of a Penuah). There is a debate in the Poskim about that too.
These Halachos are very twisty, detailed and lengthy discussions. I was thinking about posting just a summary but decided against it. I need significant amount of time and it’ll come (under a new post).
