This question already has an answer here:
Almost all samparadayas and communities have some set of rules associated with the kshoura karma. There are rules related not just to the days on which such activities can be performed but also related to the shape and size of the shikha, sarvanga, rules for kshoura during apara karma etc. These vary significantly between communities within the same sampradaya or tradition.
It would good to compile here as to What are those standards and wherefrom are they cited.
