Overview
If you have naturally curly hair, you're fortunate because you have built-in texture. To make the most out of your long, albeit thin curls, you need a hairstyle that celebrates your texture while adding a needed boost of volume. Ladies, initially it may seem hard to believe, but you can have curly hair that ventures toward the thin side. Curls are not always thick, but they have the ability to always look fabulous.
Long Bob
When you have thin hair, wearing it really long can easily add to its fine appearance, so taking a few inches off the bottom is a step in the right direction to create volume. Flattering for your curls, a long bob ideally falls between the bottom of the neck, lightly dusting the decolletage area. This length works well because the lower half of the hair gives weight to the bottom of your curls, while the long bob style is a versatile option to display your naturally textured hair.
Loose Waves
Romantic and ridiculously easy to achieve, wearing your curly hair in long, loose waves is a showstopping hairstyle choice. For best results, your hair should be no longer than the middle of your arm — this way you still have length that's versatile, but not extreme. Your natural curl pattern is relaxed for this hairstyle because waves are looser, which adds to their relaxed look. To achieve your waves, you could opt to use a curling iron, spray and finger-comb, or twist damp hair, let it set overnight, unravel in the morning and style. The final results are beachy waves that are fun and flirty.
Voluminous Curls
Arguably the best way to wear curly hair that's long and thin is to pump up the volume with voluminous curls. First things first, lop a few inches off the bottom of your hair for movement and added thickness. Then the fun part begins because the key element to this style is incorporating big, sexy bombshell curls that would make a supermodel jealous. Since you're applying texture on top of texture, feel free to have a little fun and alternate the size of your curls for a truly massive mane.
Layered with Bangs
Layers are so essential to the overall look and feel of a hairstyle that they should probably be incorporated whenever possible. Long, thin, curly hair is no different, because adding layers only makes it look thicker and move with ease. Another quick tip for adding mass to fine locks is to wear bangs, especially those that come straight across the forehead. However, the bangs shouldn't be too chunky because they can easily have a poodle-ish appearance when incorporated into curly hair.
