In "Eunoto," a Maasai ceremony that happens about once every 14 years, every male of warrior age has his head shaved (and sometimes the eyebrows) to symbolize equality of all the warriors as one age set. Since circumcisions happen over a 7-year period, senior and junior warrior classes are created between the older and younger warriors. After this day, all warriors are considered of equal status, but younger warriors are still to respect their elder warriors.
