I was a kid and saw this film on TV in the 80's. 

It starts with a crashed ship somewhere in the desert. There is a man who's an alien but I don't remember the plot... I think he just wants to go home...?

He meets a woman and reveals that he's not from Earth and take off his "disguise", still looking quite human but with strange eyes and no hair...

edit :

thanks for the answers !  
definitely not starman, it was cheap, made for tv.
