This is Dr. David
your hair will slowly regrow back when your body's nutrition helps heal back your hair follicles.
your hair follicles need a lot of nutrients to make hair including iron, protein, B12, folate, biotin, and many other nutrients.
new hair I'm sure has already started to regrow.
hair grows slowly about 0.5inches a month.
so it can take a while to see new long hair.
let me know if you have questions.
