First and foremost I want to say that as someone who doesn’t have a clue as to how wig making actually happens that looking into this was interesting. First it’s one of the most time consuming tasks that I’ve ever seen happen. The sewing and piecing along can take months especially if it’s as fragile as human hair. Here’s what I can say about it.
If you’re looking at for example the intricacy in making blonde human hair wig then you could go down to your local wig shop to look at the process. Maybe even get a custom job where the wig maker could help you decide on a style that suits you best. Human hair wigs aren’t cheap after all so you want to get this right the first time.
So the question is where do most human hair wigs come from. The answer is Asia, specifically India, China, and Indonesia. The hair is then taken to stylists who bleach and dye it to the different hair colors of Western clients from red to of course blonde. Their then shipped to companies and shops all of the world. If you’ve ever seen the movie Good Hair then you’ll know that dying the hair can take hours to get the different shading just right.
All of the manual labor that goes into making human hair wigs is the reason why most are at minimum $100. The better quality the hair the more expensive the wig.
