hmm.. i think that maybe i don’t understand the dilemma, but if you’re not sure whether or not you can use a trim, you can kind of tell by the way your hair behaves, depending on your hair. mine, for example, doesn’t curl the right/normal way when my ends are in bad shape, and when i do bantu knot outs, it always looks extra frizzy. im not sure what your hair’s temperament is like though.
when all else fails, ask your stylist. s/he’ll know!
