text: did diana, princess of wales dye her hair? when i see her when she was a kid to young teenager, she had brown hair...then as soon as married prince charles she had blond hair.... her entire personna changed after she became part of the royal family.  i believe her hair was double-processed. it was lightened and she had "highlights" added. hey, when part of your job is to wear a sparkly tiara, your hair had better shine, too!
