Aspects to Take into Account When Buying Wigs for women Many factors influence the cost of an wig. Human hair wigs are the most costly, however some models are constructed from synthetic materials. Hair lace made from natural hair combs are also among the most costly. While they're often more affordable but they're more prone to wear and tear. It's possible that they'll be affected by humidity and the weather , and could need to be dyed or styled to look its best. Given these issues you need to think about whether the price of a natural human hair bob is worth the additional cost.
