Q1: In general, wigs are hot and itchy - especially for someone with a bald head. No matter how open the wefting is, not enough air can get through to cool a naked noggin - especially where the heat is over 100 degrees all Summer. I have come home from the grocery store or errands and virtually ripped my wig off because my head was sweating so much. I have friends that say shorter wigs are cooler from being off the nape of your neck, but you couldn't prove it by me.
As to itchiness, its generally the wefts (intersections where the hair layers / bands are sewn to the vertical ribbons) that are the most problematic. The velcro adjustors can expose some hook & loop, which hurts / itches, and the illusion lace fronts can be made of very stiff fabric - also causing itches.
A lot of people try to eliminate these offenders by wearing wig caps, wig grips, or using scalp protector. And, cotton wig caps can help absorb sweat.
Speaking of sweat, a lot of women wearing wigs are menopausal, which just adds to the heat problem. Folea wigs have custom made bases to exactly fit a bald head and hold in place with a vacuum syste, but their bases are silicone; I've heard they are wonderful human hair wigs for about $5k, but that your scalp sweats in them and the sweat has no where to go.
I also personally believe that comfort has to do with the materials a wig is made from. Synthetic clothing is hot, so why wouldn't synthetic wigs be hot also? I, personally, choose to wear cotton beanies with a colorful scarf a lot of the time in the hot months.
Q2: The biggest problem with wig suppliers is weeding out the good from the bad. There are quite a few large wig companies that are well known, reputable, and carry a large variety of popular brands; there are quite a few reputable smaller companies that specialize in only a brand or two, or that custom make wigs.
A huge problem that I've seen on many facebook groups is getting the right color wig. We all know that computer monitors show colors differently, so it can really be difficult to pick a color. There should be a standardized color chart among the major US wig sellers. Some use color names, some use color numbers; some change the name of an established color. Its virtually a free-for-all when it comes to color.
You roll the dice with online ordering and sometimes you win and sometimes you lose. When you lose, then you get into return policies and restocking fees. Some are absolutely outrageous - you pay to return ship with insurance plus a 30% restock fee.
Even quality control with some of the big wig companies varies. You can order 2 of the exact same wigs and the style, hair length, density and color can vary.
Then, there are the darn Chinese companies that pop up everywhere across the web, on eBay, Facebook and other places, and more than likely you will get a cheap costume wig, an inferior product that can't be worn, or nothing. Advertising photos are ripped off from u-tube vids or actual sites in a blatant scam, and the wigs can't be returned because of return shipping costs to China.
