Thanks for your compliments, GoGirl! I read a tip by you the other week about hair.. I believe you said that you use this sort of spray that helps with frizz because it replaces the plastics? Or something? Ahh, I wish I could remember!

Anyway, on with your quesiton.
I will wash the pony first, using Bain de Terre shampoo and conditioner [it's like 20 dollars a bottle, but I just had it lying around because I seem to have a strange obsession with collecting different shampoos and conditioners, so anything is fine], rinse it all out, then bring her to the couch. In extreme cases, I'll leave conditioner in their hair at the sink for about an hour or so, then rinse it out. From there, I put on either Family Guy or Law and Order, and get to work.
Step 1 - Spray mane and tail, doesn't really matter how much you use. I use about 2-4 squirts on them. I usually let them stand with it in their hair for about 5-10 minutes.
Step 2 - I then use my cheapy flat iron I picked up at Wal-Mart for 10 dollars last summer. It's nice and small, so I can give their manes and tails that cute little flip. I only do this with pony's with straight or moderatly wavy hair since I love original curl.
Step 3 - Divide the tail into 4 [or however many you want - but no less than 4] parts. Flat iron each one until it's dry or damp [I do it until it's dry, but either way is fine], pausing each time to comb [I use a metal comb] their hair.
Step 4 - Divide the mane into 3 [or however many you want - but no less than 3] parts, flat iron each one. If you want the little flip like I gave Scrumptious, then I just take a part of her mane and curl it with the flat iron like you would with a curling iron. But SMALLER the flat iron = BETTER results. It doesn't have to be expensive, just small.
And that's that! Oh, and don't worry if it sizzles, that's normal. ;D You don't necessarily have to get the Hemp stuff, I'm sure any detangler will be fine. I would buy one with heat protector JUST to be on the safe side. ThermaSilk has one that is AMAZING. I used it before my Hempz stuff.
