I get claustrophobic, all these open doors around

I wonder what to do with my hair.. Should I color it again or just leave it and let the dark color fade? Unfortunately the roots will start to show in the contrast of the henna, humph. Here're some pics of my color history, I couldn't find the super old pics on this computer though, I'll save them for another day. Hah.

 I know, I am ridiculously tan! hehhehe. 

Hrm. some pictures are way before Estados Unidos as you can see.
