Night time hair care is key to retaining moisture! You have to make sure that you’re protecting your hair at night. This means you need a satin bonnet or pillow case. If your hair is natural you should try to braid it or twist it nightly or use the banding method (it makes for a really full bun). Also if your hair is pressed, rolling or wrapping your hair is good to keep your ends protected. Also castor oil and avocado oil really help!
