Have you tried using a sculpting lotion or a molding mudd,any good hair salon will have a variety of these products and might possibly have some answers for your dilemma.You might get results from overnight pincurls or rollers?If this doesn't work why not try a stylish cut for straight hair?I have naturally curly hair and I would love to try a shag or feathered,etc.........unfortunately,that 's not in the cards for me.Good luck!
