Kids Next Door Hairstyle Headquarters, otherwise known as Sector HH, is a haircut place (not to be confused with the KND C.H.O.P.S.H.O.P.) where the best KND barbers help to cut kids' hair. The staff include operatives Numbuh VO5, Numbuh 411, Numbuh 90/40 and Numbuh 622. KND operatives and children come here to get their normal hairstyles back, after their fathers take them to adult haircut places where adult barbers mutilate their hair, like what happened to Numbuh 85 of Sector W . Numbuh 1 is a sort of mystery at Sector HH, as the hair specialists are always trying to figure out how he lost his hair and how to get it back (unbeknownst to them, the Delightful Children From Down The Lane are responsible for his baldness and he will never get his hair back).
