How to Curl Your Hair

First, divide your hair into sections. If you're planning on curling your hair, leaving 'em in for 10 minutes, then running out the door, use the "alternate" method - one curl on each side of the head - so that the curls are even on either side. Run the comb down the back of the head, then spritz lightly with water or leave-in conditioner. Generally, around 12-16 curlers will be enough, and you should use the same number on each side of the heat.

To curl, take a small section of hair, around 1-2 inches in width and a half inch or so in depth, brush to remove tangles, and hold the curler at the bottom of the section of hair. Holding tightly, roll the hair upwards, underneath, stopping either around ear level or at the roots, depending on the end result you want. Fold the ends of each curler over the hair-wrapped bit, making a squashed spiral shape. All of the curlers should be rolled up and underneath hair, and the ends of the curlers should be folded over each other to prevent the hair from slipping out. Keep going til you're out of curlers and hair. This generally only takes about 10 minutes, and you usually won't need a mirror or anything fancy. Some bloggers recommend using various tools, but the more you do this, the easier it gets - and you really don't need anything other than your hands and the rollers. 

The End Result

If you want big, bouncy, Hollywood curls, you'll want to use larger rollers, and roll them right up from the tip to the root. As the hair dries, it'll add volume to the root and you'll have that just blow-dried look. If you want big Hollywood curls but you don't need big volume at the roots, just roll the rollers up to your ears. If you're trying to kid everyone that your hair is naturally curly, then you'll want to curl right up to the roots so that it looks like your hair just grew right out of your head that way - or, if you're trying to get lovely beachy waves, just curl up to the ears and then spritz with a salt spray.

Curling for 10 Or Curling Overnight

If you're curling your hair for 10 minutes, you want it to look perfect, pretty much instantly, so you'll want to use a few smoothing and perfecting products. A leave-in conditioner is a good idea - but you can also use some dry oil spray, some serum, or some oil on the very ends. Sometimes hair can look a little dry, especially if it's prone to being frizzy, so make sure you take care of the ends. If you're curling it overnight you'll probably only want to curl it to the ears, otherwise, it'll be quite uncomfortable to sleep - and if you can, use a silk pillowcase to reduce frizz! Other than that, all you need to know: make sure hair is a little damp, use the right products, and keep the rollers in until hair is completely dry. Viola! Gorgeous curls, easy!
