DayDreamist There are a couple that I've made.
1) You have to know which kind of heat protectant works for you. They are not all created equal. I've tried TONS of them. I find that serums (Chi Silk Infusion, Fantasia IC, etc) tend to weigh my hair down. Serums leave my hair greasy looking and limp. I get very little "swang" when I use them. Then you have the liquid kind or sprays.(Organix Brazilian Keratin Flat Iron Spray, John Frieda Full Repair) I like those kind. They leave my hair feeling silky and soft, but it takes a lot to get full coverage. My personal favorite is Got2Be Crazy Sleek Flat Iron & Blowdry Lotion. A little goes a long way, my hair is soft, bouncy, shiny, and has lots of "swang"
2) You have to pay attention to the products you use when doing just blow outs. I've suffered from "crunchy" blow dry hair, as well as just plain huge frizzy hair. Again, I'm not very good at blowdrying my own hair.
3) Make sure to incorporate protein. Heat can cause the hair to become weak and brittle. So I will do a moisture DC, then cowash with a protein condition before I use heat. Or vice versa.
4) I never thought it mattered much, but GREASE is really good to have if you use heat. Besides my HP, I mostly use natural products. So the grease I use is by Njoi Creations Sweet Coconut Pomade. I use a dab just before using heat, and daily to M&S my ends.
I'm being long-winded again. Those are some of the most important things to consider when adding heat as a regular part of your regimen. I'm giving examples based on my experience and my hair of course. But I hope to have helped in some way.
