Prehensile Hair

As a free action, You can cause the hair on your head to grow up to 10 feet long or to shrink to its normal length. While your hair is in it's lengthened state, you can manipulate your hair as if it were a limb with a Strength score equal to your Charisma. As a bonus action you can use your hair as a weapon (Finesse, Reach, Disarm) which you are proficient with to attack enemies dealing 1d4 bludgeoning damage + your modifier on a hit. Your hair can also envelope most of your body giving you the same effects as wearing cold weather gear.
