OMG!! I've had this stuff in my bathroom for months but never got around to trying it. I know I said my hair is helmet-proof now, and it is, but it does kind of go flat. I just came in from mucking after morning naps (don't ask), and I'd been wearing my cowboy hat since it was raining out. I have a party to go to this afternoon and didn't really want to wash my hair. I figured I had nothing to lose, so I squirted some of the stuff on my hands and just ran my fingers through my hair. Honest, it looks like I just stepped out of the hairdresser's!
It's by SAMY (I have no idea what that stands for) and the product is called "Icing" hair restyler. My hair is stick-straight in the front and curly in the back, and it worked on both without disturbing my terribly elegant (cough, choke) blow-dried look at all.
Just figured it was worth sharing. I can't vouch for how it works on snot-crusted hair, but if it's reasonably clean (brush the dust and hay dirt out first), it should be just fine.
