Payot

Payot are worn by some men and boys in the Orthodox Jewish community based on an interpretation of the Tanakh's injunction against shaving the "sides" of one's head.

[2] The word pe'a was taken to mean the hair in front of the ears extending to beneath the cheekbone, on a level with the nose (Talmud – Makkot 20a).

The Lithuanian Jews are less influenced by Kabbalistic practises, but still retain sidelocks to a degree, in a small number of variant styles:
