French Women Have Perfect Hair

I am having hair issues...I'll just admit it. Please excuse me if I talk about hair and hair-related anxieties a bit over the next week. I am going through this weird phase right now: I really want my hair to be its "natural" color. But, I've been coloring my hair for so long that I'm not even sure what that natural color is. My stylist and I tried to make our best guess (light brown-ish?), but I'm just not sure I like it...I keep thinking it looked better when it was dyed dark brown. But, I AM SO SICK of coloring my hair. I need a break from all the messy, smelly dye right now; I will start turning gray and have no choice but to color my hair soon enough...
This brings me to a nagging question: I just want to know why French women (actresses & singers, to be more specific) have perfect I-don't-color-it-or-style-it-but-it-still-looks-awesome hair??? Just take a gander at the perfection of Francoise Hardy, Jane Birkin [Update: I know now that Jane is British...I just associated her with french music and the French films she starred in -- the French sort of adopted her I suppose. But, yes, she was born in England. I am blissfully imperfect from time to time...oops.] , and Lou Doillon. They all look like they have their natural sunkissed-haircolor -- just the right shade between brown and dark blonde. Mon dieu! Why can't I be French?
