In one sentence, describe what the following article is about:

Gather your hair into your favorite updo, such as a French twist or side bun. You can also do a braided updo; depending on your hair length and personal style. Make sure to hold your hair in place with hair ties or bobby pins so it doesn't fall out. You can use this technique with nearly any updo, but it'll have the most dramatic effect on traditionally sleek styles like French twists and tight chignons. Using a blow dryer will completely destroy your updo. When you're finished spraying the sea salt, let your hair dry naturally. Once it finishes, you are ready to show your cute updo to the world! The texture provided by the sea salt spray should help prevent your hair from sliding out of place, which may increase the longevity of your updo.
Style your hair into an updo of your choice. Let your hair air-dry.
