So here is how I use them. I spray them with a thermal spray then roll them in my hair using end wraps as I found that with out the end wraps my ends were too sloppy. First I let them heat up for 15 to 20 minutes. I roll them all under using mostly pink smaller rods in front although I will alternate some larger orange in for variety.
Leave them on for about 20 minutes more perhaps put on my make up or pick up the house. Then unroll and brush out and spray.
Also the lovely Fleur of Diary of a Vintage Girl has done a tutorial on using the hot sticks which is how I found out about them Fleurs hot sticks tutorials. She has some other tutorials on her blog too so please check it out.
