. Beachy hair is usually achieved through the combination of sun and the salty ocean spray. If you don't have access to a beach, you can fake your way to California girl hair by using a leave-in salt spray, which will create a thick, wavy texture to hair of all colors, lengths, and textures.  You can make your own salt spray using water and dissolved table salt, or you can purchase a sea salt spray from your local salon. If you do use a sea salt spray regularly, be sure to condition your hair, as well, as salt can be extremely drying. Because California is known for its sunshine, it comes as no surprise that the quintessential California girl has sun-bleached hair. To mimic the fresh, youthful appearance of beachy hair, you can have your hair highlighted or bleached in a salon, or you can do it yourself by applying some lemon juice to your hair and sitting in the sun over the course of a few days. Typically, California girl hair is associated with hair that is at least a little bit wavy, rather than hair that has been straightened or relaxed. Because Californian style is focused on looking effortless and relaxed, allowing your hair to embrace its own natural texture, whether that means a tight curl or a barely-there wave. If you do not have wavy hair, you can tease it, add a salt spray, or even create uneven and messy curls with a curling iron. Although long hair is not a strict requirement, the California girl style is usually embodied by long, flowing hair. If you are able, opt for long, let-down hair in a natural texture. If you do have short hair, make sure you play it up by making it as messy and wavy as you can.
