Hmmm.... maybe. At this point I'm willing to try anything but can't afford the unicorn tears which might be the only chance I have of taming this mess on my head. Except when I'm complaining about it, I'm mostly ok w/getting older but I didn't know the years would take out my waist AND my previously pretty hair.

My inner chemist says that the reason to leave it sit for two weeks is for the sodium bicarbonate to convert to sodium carbonate (aka washing soda). You can accomplish this more quickly by heating to over 70°C, which allows the extra carbon to escape as carbon dioxide.

From that perspective, sodium carbonate is a really fantastic, cheap detergent. I have not checked, but it might actually be cheaper to use a bit of washing soda directly in the water instead of converting bicarbonate.
