help! bonds showing!

Hi,
I'm new to this forum but have gained a wealth of knowledge from you ladies for quite a while so thanks! Finally, I have an issue of my own that I can't seem to find written about-- perhaps someone can help:

I have been wearing fusion extensions for about a year. Recently, I have been having a very hard time disguising the bonds on top. At first, I thought my stylist had just put in too many bonds up on top, so I removed them myself. While I fixed the bond-showing problem, I made my hair look like a mullet!!

My natural hair is thin and wavy. However, I have been wearing straight extensions and straightening my hair everyday. I recently ordered body wave hair (it hasn't come yet) so that I can start leaving my (real) hair wavy to perhaps hide the bonds better.

Can you guys give me any advice as to how I can keep my bonds from showing on the top? I was actually thinking of trying the seamless kind for my next round to remedy this problem, but I'm trying to avoid having to do all the research that it would take to convince me that a new method is the way to go.

Thanks for any input!
