I've gone through boku wigs over the years, both human and synthetic, in my search for the perfect one, and I would say go with human hair. Yes, there are some fantastic synthetics out there, but nothing to me beats the realism of the one I have now, especially for everyday wear. Upkeep has never been a problem or hassle, and the great thing about it is I can color it to get exactly what I want. I wear a Remy human hair wig from Wig Pro, and I am constantly being complimented about my hair, people are amazed when I tell some that it's a wig. I did have it styled at a salon, your better human hair wigs usually come with 20-30% more hair than needed for that purpose, any wig looks better when it's styled for your face.
These do come with a higher price, I paid $460 for mine, but it's money well spent because of the quality, and it will last for a long time. I also saved a lot of money by getting it off the Internet, they cost double that in the stores. I had several Paula Young wigs when I first started going out, and while they are a good deal for the money, none of them lasted very long, the same for a cheap human hair one I got off eBay. If money is an issue, then stick with synthetics, I had a Revlon that was very nice and only cost $85 off the Internet. What your friend can do is go to a wig store and try on different models to see what works, then get it off the Net. I know that's not exactly fair to the store, but saving half price is saving half price any way you look at it.
