Well, I think curly peyos depends on a couple of things. First, if the man/boy has curly hair, then he will have curly peyos. How curly will depend on how curly his hair is. Now the perfect bottle curl that the chassidim wear is not so easy to come by and most of the time they will have to do what was suggested above and that is to get a “perm” to the peyos hairs.
As far as what LUL saw with a man curling his peyos, that is very often seen in chassidish neighborhoods since the men go to mikvah daily and will often spend much time doing this curling activity with their peyos to restore the shape and curl to them. If a man goes with “batteriot” as they call it here, the very tightly curled ones that go behind the ear (not to be mistaken with straight litvish peyos that also go behind the ear), then those can be arranged less frequently, twist tightly and put behind the ear. Gerrers often wear their peyos up under their kippahs.
