“Now this is actually a lot easier than it may seem. If your hair is already of the correct length, all you need is a good set of medium barrel hot rollers!
I recommend using hot rollers of about a 1 inch diameter. When you’re putting them in, be sure to hold them up and out from your head when you start rolling, so that they go all the way down to the base of your hair and don’t just hang there.
Make sure not to use too big of sections or the heat won’t adequately penetrate all of the hair. You also want to be sure to roll them in the direction you want the curl to go.
For instance, in the pic above the curl goes toward her forehead and under, so you want to roll the hot roller toward your forehead and under when putting it in.”
