Aspects to Take into Account When Buying Wigs for Women A variety of variables determine the price of an wig. Human hair wigs tend to be the most costly, however some models are made 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 as well as the weather and might need to be changed or dyed to appear its best. Given these issues you must consider whether the cost of a natural human hair Bob is worth the cost.
