Occasional mis-shaped hairs are not necessarily abnormal. With anything approaching a normal diet, it is difficult if not impossible to be deficient in vitamin C; and if you are, it is exceedingly unlikely while taking supplements. This sort of thing needs in-person care and advice: discuss with your GP or other primary care provider. Good luck.
