Blond Hair in Back, Skull in Front!

I was born in 1971 and I remember a trailer that used to be shown on TV for a movie that I believe would have been about the time I was 4-7 years old. Used to scare the "you-know-what" out of me. Here's what I can tell you about the commercial (that I always watched with one eye shut):

The trailer opens with the back of a woman's head shown. She has long, blond hair and it is being slowly brushed. Then a hand places a flower in the hair and a creepy voice says: "a flower there..." at which point the head turns around to reveal a SKULL!!

I seem to remember the movie with an odd title that started with an X, and I have always wanted to find and watch this movie and or trailer if ANYONE can tell me what it is. Would have been from 1975-1978.

Thanks.
