After sitting a minimum of four hours to install your butterfly locs, you'll want to keep them looking the best to make all those bathroom and stretch breaks worth it. Butterfly locs can last from four to six weeks with the proper maintenance. To keep your hairstyle neat for as long as possible, cover your hair at night. Wrapping your locs with a silk scarf or wearing a bonnet will prevent strands from unraveling as it rubs against your pillow. You can also opt for a satin or silk pillowcase to protect your hair while you sleep.
It's essential to care for your scalp and natural hair under the extensions too. You don't want to neglect your mane while it's in a protective style, especially since synthetic hair pulls moisture from your natural tresses. To hydrate your hair, apply oils like olive, argan, or almond oil as needed straight to your scalp and massage it in. You can also put the oils in a spray bottle to spritz your roots and the length of the loc.
However, to really make your hairstyle last more than a month and keep it healthy, you'll need to wash it.
