I wear wigs and I will tell you, I have yet to buy a wig that is perfect right out the package. Also I secure with bobby pins and I find this better than the clips. For people who wear wigs every day, the clips WILL EVENTUALLY break your hair.
The key is to learn HOW to make your wig look as REAL as possible. For me the shine on the hair is what makes it look fake, that can be toned down with speedstick deodorant, you wipe it down the shaft of the hair and rub your hands from the right tot he left and it will take the shine down.
Also, I find that you need to use a wig head when not wearing the wig and also you need to use hair spray so the hair is not floppy up and down but is more firm and in place. I also find that even with lace wigs it is best to go as close to your natural color so you can take out a small small amount of your edges in front of the lace, so people see your hair. There are so many tips on youtube. I also find the black color can be too harsh and it is best to order the dark brown or off black color.
Wigs are a true blessing for me.
