The same ones that I posted as changing direction do this on that side all the time. I separate it into 2-3 clumps usuallly. It happens a little in other places from time to time, but those ALWAYS do it.
My Hair:
2c
Fine, low porosity, med/high density
BSL - going for mid back to waist

HG: currently
just washing with a low poo that contains protein (Alba Naturals Coconut) and using Suave Naturals Coconut as both a RO and LI. No stylers right now, but this gives me pretty good curl, definition, low-ish frizz, and it feels and looks good. Also an occasional PT (liking the Palmer's Coconut Oil Formula which has cones) seems to be key for me.
