Plain and Simple…the Halacha is for a woman to cover her hair.
How she covers it is her choice. A shaitel, a tichel ,a Shmatte, a Hat etc. Nowhere does it say that a woman should look ugly in the choice that she choses to cover her hair. Boruch Hashem because of advanced technology we are able to have shaitels that don’t look like a a mop or broom. As long as a womans hair is fully covered, then she is following Halacha.
If you want to talk about women who pull out the whole front of their own natural hair to blend in with their shaitel, or women who wear head bands with 2-3 inches of their own hair showing…that’s another story.
