Ikharo are linear keloid markings depicted on the forehead of Uhunmwu-Elao (commemorative heads) in groups of three or four above each eye. The exact meaning of Ikharo is debated; some have argued that they relate to the gender or tribal identification of the person on whom they are depicted.

The Udahae is a forehead band made from coral beads and worn by chiefs. Sometimes a white Igan (feather) from the Oɛɣohɔ (vulturine fish eagle) is tucked into the left side of the Udahae. According to Benin oral tradition, the Udahae was introduced by Ọba Ezoti, the first son of Ọba Ewuare I. During his coronation, Ezoti was shot in the forehead with a poisoned arrow. To stop the bleeding, a band of red beads was wrapped around his forehead while he made public appearances. Fourteen days later, he died from his wound. Since then, Benin chiefs have worn the red-beaded Udahae around their foreheads to commemorate the cap used by Ezoti to stop the bleeding (Egharevba 1968, p. 21).
