LuVmyFaM-
Do you and your husband have a rav? Every sefer is nice to learn from, but you need to know that rabbanim occasionally disagree with each other, as in this case, where some will say like the Yalkut Yosef and some will strongly disagree and say that a wig is absolutely l’chatchilah and you have nothing to worry about. I recommend that you have one rav who you follow in all aspects of halacha (not really my own recommendation, the gemara says so), so you won’t be like a blind person groping in the dark each time you hear of one person who is extremely machmir.
