What exactly would you like to know? I can give you some basics.
It's always worth splurging when it comes to wigs. You can get an okay wig for sixty bucks, or you can get a gorgeous human hair wig for a few hundred. It's also worth investing in a good, breathable wig cap, especially if you'll be wearing it constantly.
Look for a wig that's believable. It's all well and good to get, say, and long black wig, but if you have shoulder length blonde hair, it's going to look a bit silly and people will realize something is up. Go with a wig with realistic fibers, that matches your natural hair and complexion. Also, go with a length that you know you can manage.
You can usually wash hair like most extensions: CAREFULLY, with a mild shampoo. You don't have to wash it every day, of course. How long you can go depends entirely on you. If it looks dull, or worn out, or oily, wash it. Avoid blow drying it too much, and steer clear of backcombing/teasing. Use a volumizing shampoo, etc., if you need the boost.
Most beauty supply stores have good selections of wigs, and the girls who manage the wig section usually know their stuff. Just keep in mind that a wig may look acceptable on the shelf, but could look ridiculous on an actual person. Most stores let you try on several wigs, so take advantage of that. Good luck!
