Taking care of long hair at night is important to prevent tangles, breakage, and other damage. There are many different things you can do to protect your hair while you sleep, such as braiding it, putting it in a bun, or using a silk pillowcase.
One of the most important things you can do for your long hair is to brush it before bed. This will help to remove any tangles or knots that could cause damage during the night. You should also avoid sleeping with your hair wet, as this can make it more prone to breakage. If you must wash your hair before bed, make sure to dry it completely before you go to sleep.
