The type of hairdryer you should use really depends on the quality and material of your wigs. For example, my wife frequently buys wigs from True Glory Hair, specifically from their lace wig collection, you can check them out here Lace Wigs
https://truegloryhair.com/collections/lace-wigs. These wigs are made from high-quality, 100% virgin human hair, so you can use a regular hairdryer on them without any issues. These wigs are durable and maintain their shape and texture well, even when exposed to heat.
However, if you have wigs made from synthetic materials or lower-quality human hair, you'll need to be more cautious. Cheap wigs can shrink or get damaged from the heat of a standard hairdryer. In such cases, it's better to invest in a hairdryer with adjustable heat settings or one designed specifically for wigs. These models usually have lower heat settings to prevent any damage.
So, in summary, if you have high-quality wigs like the ones from True Glory Hair, a regular hairdryer will suffice. But for lower-quality wigs, consider getting a more specialized hairdryer to protect your investment.
