Oh and here's a blog I like to read, only I just don't read it super-often because she doesn't post nearly enough.
Anyway, I read this post here and it's pretty perplexing, so I clicked on the comments and read through several, and this one made me particularly happy. Good stuff.
Olive oil. Seriously, if it worked for Cleopatra, who are we to argue? This is how I do it:
Pick a night where you're going to stay in anyway. Plan on wearing a button-down flannel or pajama shirt and hanging out in front of some cheesy dvds.
Fill your palm with just about a teaspoon of olive oil, no more. Really you don't need much at all; it spreads like an oil slick (oddly enough). Massage this into your scalp. Don't worry so much about the ends of your hair, but go ahead and dig those fingers into your itchy, grouchy scalp till you start making noises like the lady in that risque Clairol Herbal Essences commercial where she somehow miraculously washes AND DRIES her hair in an airplane bathroom. (Who IS this woman? I can barely manage to wash and dry my HANDS in an airplane bathroom. You should take my advice anyway, though.)
Ok, now it gets weird: take a plastic grocery bag and pull it around your hair till you can knot the handles at the top of your forehead like Aunt Jemima. The heat from your head in that suffocating plastic pretty much melts the oil into your scalp and hair. At first you feel a little goofy, but after a while your head gets all warm and happy and you start grooving with it, especially if you thought ahead and opened a bottle of wine and popped in a movie before your hands got all greasy and now you're watching Roman Holiday through a chianti haze. You want to do this for at least 20 minutes.
Now head to the bathroom, carefully remove the plastic bag, and wash your hair. (This is where the button-down shirt comes in handy, because your hair is a mess and you don't want to try to pull anything over your head. You may also be wondering why on earth you trusted some internet lurker, but it's far too late now so just go with it.) Shampoo twice, thoroughly massaging the scalp again and rinsing the shampoo all the way from roots to ends, and condition once if it's the rinse-out kind. No leave-in stuff this time. (Ok, look, you can always put in tamer tomorrow if it gets out of hand.) DO NOT - I repeat: DO! NOT! use a hairdryer. Towel dry and make yourself a turban and go finish that movie and bottle of wine. Some cheesecake at this point is also nice.
You can go to bed with your hair still wet if you're not particularly prone to cowlicks. Tomorrow morning, after delightful dreams of Gregory Peck on a Vespa, you will wake up with some seriously bodacious cornsilk locks.
Seriously, I might just do this for fun one night this weekend. Anyone who wants to join me, grab a plastic grocery bag and head on over.
