Aspects to Take into Account When Buying Wigs for Women A variety of variables determine the price of an wig. Human hair wigs are most costly, however certain models are made of synthetic materials. Natural human hair lace comb hats are also among the most costly. Although they're usually less costly but they're more prone to wear and tear. They'll react to humidity and the weather , and could need to be restyled or re-dyed to look its best. In light of this you need to think about whether the cost of a natural human hair bob is worth the additional cost.
