The causes of scabs in the nose can include the use of drugs that are inhaled through the nose. Other causes include extremely hard blowing of the nose due to infection or the common cold, picking of the nose that damages the skin inside the nose, and extremely dry weather conditions. Dry weather can sometimes cause the skin of the nose to become dry and peel. A great way to treat scabs in the nose is by spraying the inside of the nose with saline nasal spray.
