Wigs for Everyone- A Dermatologist’s Honest Guide to Choosing and Wearing Wigs
Wigs 101: What Dermatologists Won’t Always Tell You About Wigs
As a dermatologist, I honestly don’t like touching this topic—it feels a bit like admitting we can’t fully solve your hair loss problem. But, for the sake of everyone’s curiosity, and considering that hair loss treatments often take a long time, I think it’s necessary to give a proper guide on some “hot and cold” knowledge about wigs.
1. Why Wear a Wig?
The answer really depends on the person. Some people use wigs because of professional needs, like actors or news anchors. Take the hosts on CCTV News for example—their hairstyles remain unchanged for decades. Without wigs, which stylist could really pull that off?
Some wear wigs for novelty or style experiments. If you have long hair but are hesitant to chop it short, you can try a short wig first to “test the waters” before making a drastic cut. Or if you have straight short hair but want a new style without commitment, a wig can give you that motivation.
More commonly, people turn to wigs out of necessity. Hair loss or balding happens for a variety of reasons, and not everyone has the courage to shave it all off. In these cases, a wig is the most practical helper—covering the scalp imperfections and giving confidence, both in hot and cold weather.
2. How to Choose a Wig
The first thing to consider when choosing a wig is material. There are many types, and I only recently learned the details after a deep conversation with a mall wig consultant. Now I can share this knowledge with you.
a. Human Hair Wigs
Most wigs sold at department stores are made of real human hair. Why? Because it looks natural. Think of it like organ transplantation: the best choice is your own tissue, the next is compatible human tissue from others, and lastly, synthetic or artificial material—used only when the first two are unavailable.
Human hair itself comes in many types depending on the region: Chinese, Indian, Brazilian, Burmese, Vietnamese, Mongolian, etc. Different ethnicities mean differences in hair texture and curl. Asian hair tends to be straight and coarse, with Chinese hair being the smoothest to touch. Brazilian and Indian hair are softer and curlier, making them suitable for Western styles and often used for hair extensions.
The benefits of human hair wigs are clear: you can dye, perm, curl, blow-dry, and style freely, and they’re relatively easy to maintain. The downside? They’re expensive, often costing thousands to tens of thousands of yuan. When I saw the price tags, I made a personal decision: no more haircuts for me—when my hair reaches my waist, feel free to “buy it” from me.
b. Synthetic Fiber Wigs
Another large category is synthetic fiber wigs, made from chemically produced fibers. They are “fake,” but affordable. Common types include PP fiber (polypropylene) sold online or at local markets. Higher-end fibers like Japanese Kanekalon and Toyokalon can closely mimic human hair, but good ones aren’t cheap. After all, the cost is not just the material but also the design and styling—like luxury fashion items, expensive for reasons we don’t always understand.
Some technical subtypes of synthetic fibers include:
-
Regular Temperature Fiber: Often used as filler in mixed wigs. Affordable, but low realism, not heat-resistant, and flammable.
-
High-Temperature Fiber: Can withstand heat up to ~160°C, allowing styling with curling irons or flat irons. More realistic and easier to manage than regular fiber, reflected in higher prices.
-
Protein Fiber: Currently the closest feeling and realism to human hair, explaining why high-end synthetic wigs can rival human hair in price.
-
Flame-Retardant Fiber: Upgraded fiber that resists burning and behaves similarly to human hair under flame. Very costly and not widely used, as many would rather buy real human hair at the same price.
3. Important Considerations
Wigs have a large market, but fake hair is still fake. There are limitations that technology has yet to fully overcome.
-
Wigs are essentially styled hats. Buying a wig for a few thousand yuan gets you a ready-made hairstyle. If you want to change the style, you’ll need to buy another wig—this can be an endless cycle. Hairstyles are also limited; for instance, you may need bangs, cannot fully expose your hairline, or cannot achieve your ideal length. On the upside, you can try wigs before buying, without depending on a stylist’s skill or mood. Use them as you like.
-
No wig can be worn 24/7. Even the most expensive ones have a lifespan of only a few years. They need careful handling, washing, and protection from sun, wind, rain, fire, pets, and travel. Caring for wigs is surprisingly laborious and even comical if you picture carrying it around to wash after a shower.
-
Scalp health matters. Even light, breathable wigs cover your scalp. Many wearers have underlying skin issues like seborrheic dermatitis, folliculitis, or psoriasis. Prolonged use can worsen these conditions. Clean, disinfect, and give your scalp air whenever possible.
-
Wigs are not a cure. If you’re experimenting or want temporary style change, go ahead and enjoy. But if you’re hiding hair loss, scalp disease, or dermatitis, active medical treatment is necessary. Hair and scalp issues are serious, and delays in proper care can leave you dependent on wigs long-term. Always consult a doctor rather than self-managing.
