Hair extension advice,,,help

Hi, need advice re: hair extensions. I had them put in for the first time(hairlocs) in Jan. I have had mantainece done twice since then. My real hair seems to be frizzing out more then usual. In fact when I look at my hair, I don't even know anymore where my hair ends, and the ext. begin. My real hair dries with a loose curl to it, and the extension ends look like a broom. Also, the color had just faded, and never stays in. It doesn't seem like I'm losing hair in the brush or shower, but I am getting freaked, and my hairdresser has been flaky about keeping apts with me.
