If you plan to do a knot-out, it is recommended that you let the hair air dry on its own. Placing a shower cap over the Bantu knots overnight can create a humid, steamy environment for your hair, though, which can help set the style naturally.  Using a shower cap creates a type of "greenhouse effect," allowing your hair to dry as slowly as possible while retaining enough moisture to prevent them from losing form. After you remove the shower cap, your hair will still feel slightly damp. Let it continue air drying for about 15 minutes before pressing forward. If you need to set and dry your hair in a hurry, the next best option is to sit under a bonnet dryer and let your hair dry under the warm, steady heat for 30 to 60 minutes.  Keep in mind that you will likely need about an hour for your hair to dry. Long or thick hair may take even longer to dry. It's normal for your roots to stay damp, as the hair is coiled around them. Do not blow dry knots. This will cause them to become far too frizzy when you take them down. A light mist of hairspray or oil can help prevent flyaway hair while giving your hair a subtle, healthy-looking shine. At this point, the Bantu knot-out is ready to sport around town.
