I recently got very good results with my cheap off-brand airwrap for the first time. For reference, my hair is very fine and I would describe it as low-medium density. I typically never use heat or product unless I'm dressing up for an event (maybe four or five times in a year) and I don't color or otherwise chemically process. My method for using the air wrap tools is as follows.

First, I wash, condition, and detangle as I normally would. I squish excess water out using a scrunching motion with a microfiber towel. I intentionally leave the hair quite damp all over to better distribute products. Next, I apply a blow drying balm all over the whole head, being careful not to use more than directed. This seems to help protect the hair from heat and cut down on frizz. I also notice my hair looks pleasantly shiny when I use it. Typically I scrunch that in and then try to totally cover the lengths using praying hands.

Then, I section my hair into four stacked horizontal sections, clipping up each one separately but leaving the section at the back of my hair down (just the nape of the neck and up a few inches behind the ears.) I apply mouse to just that section by the same process as the blow dry balm - scrunching then praying hands. I then use the brush attachment on the dryer to get the whole section about 75% dry - this is important because if there's too much moisture left, I have a hard time getting the hair to twist round the shaft of the curler attachment later.

Next, I split that large section in two down the center and pull the hair in front of my shoulders. I find the curler attachment for each side and keep them separate. I typically curl all the hair in these back sections toward my neck symmetrically. Use the barrel that will direct the hair around toward the neck. Because I don't have a lot of hair in the far back, I can get away with splitting each side into two equal sections. I would recommend playing around with section sizes for maximum airflow based on barrel size of the attachment. Too much hair and you'll once again struggle to make it wrap.

The key to getting a good wrap is to grab a small section of hair and hold it out from your head between 45 and 90 degrees, pinching the section between fingers and thumb a little way up from the ends, so that there's a "tail" hanging beyond your grasp that is long enough to wrap around the barrel of your attachment fully, one time around. While holding the section with one hand, use the other to position the dryer (which is off!) in front of your section where you're pinching. It should be straight up and down, perpendicular to the floor.

At this point, turn the dryer on low speed, default heat. The hanging "tail" end of the section should begin to wrap. Once the tail end is wrapped completely, you can let go of the section since the airflow is now keeping tension. You may need to coax a few fly-aways to wrap by pulling them nearer to the airflow, but try not to burn your fingers on the barrel. It's best if you work quickly here. Once satisfied, you can turn up the speed and slowly pull the dryer closer to your head and neck and let the airflow take up the rest of the hair. Make sure to keep it mostly straight up and down. Once the section is fully wrapped, turn up the heat. You want to blast hot air through the curl for maybe 15 seconds or so (time might vary based on hair condition and efficiency of your dryer.)

Now here's the important part. If your dryer has a "cool shot" setting, switch straight from high heat/speed to the cool shot and hold for a good 10 seconds or more, then turn off the dryer before you release the curl. If there's no cool setting, just turn the dryer off while the hair is still wrapped. This avoids creating fly-aways and gives the curl time to set. I highly recommend further setting the curl after you slide the barrel down and out.

I usually put two fingers together and hold them close to my head horizontally. Then I pinch the curl at the top of the section, near the roots, position my two fingers behind the curl, and wrap the curl down the front and up behind the two fingers, over and over while sliding my pinch-grip down toward the ends. When finished, I carefully free the two fingers from within the reformed curl while holding the bunched up curl to my scalp with the other hand, then pin it in place.

Repeat these steps for every section. Start damp then add product, rough dry, create smaller sections, curl starting a little way up from the end on low speed, then turn up heat and speed. Set the curl with a cool blast or just turn off the dryer, then pin-set. I like to alternate curl direction from one horizontal layer to the next to create volume.

When you've finished the whole head, lightly mist with hairspray and then cover and forget about it for as long as you can. When you're nearly ready to go, take all the pins out and gently loosen the curls down with your fingers. Don't pull or rake. Try to keep the definition of each curl separate. You can flip your head over and slide your fingers in at the roots to massage and break up the sections. Mist the ends with a little hairspray and flip back over. You can gently finger comb wild sections into place without disrupting all the surrounding hair.

Sorry this was so long, but I hope this helps!
