The wig and extension industry is currently a billion dollar industry – it’s not just Orthodox Jews who are wearing wigs. Women from all over have caught on that they can beautify themselves tremendously with hair extensions and wigs. Actresses and models wear them all the time- it’s actually quite ironic that they are wearing these wigs for glamour and we frum women are wearing the same wigs for “modesty”.
The only place in the world that has enough hair to supply the demand for human hair is India. Rav Elyashiv ruled that Indian temple hair is completely forbidden- even one Indian temple hair renders a wig assur. Since most of the hair In wigs is processed today (raw hair is actually not appealing to today’s market, hair is always processed to make it appear silky and shiny) there’s no way to test the wigs to determine where the hair comes from. So there’s definitely a serious problem here.
Sheitels are an item of pritzus and idolatry- what Rabbi is going to want to deal with that?? What will women do if they can’t wear their beautiful 3,000 natural looking sheitels anymore where they can look like they are not covering their hair and resemble the stars in Hollywood? Imagine- women might have to wear (gasp) synthetic wigs or tichels like our ancestors did and we might actually look Jewish and like we’re covering our hair
