Is there anyway to flatten a wig down so the top doesn't look so bulgy and fake at the top. I don't want it so obvious that I'm wearing a wig.

A beauty salon will tailor your wig the way you want it. You wear it, and they cut it to suit you.

Human hair wigs react the same way as the hair growing on your scalp. Therefore, you can use a flat iron to smooth out the bulginess. When washing your wig, use a conditioner or leave-in-conditioner for a smooth, bulge free look. You can also use a few drops of hair serum or pomade to help flatten the top of your wig.
