Yes it will come back see how long my hair is now, Last time I went on treatment my hair fell out by the handsfull. I freaked out I had to cut it short. But after my treatment I never cut it and it has really grown. So don't worry it will grow back. Hang in there. God Bless and keep you all through your treatment.
I had really long hair. Cut it several times because of hair lost. It's been 5 years since I took med and my hair is definitely thinner. It grew back but not nearly as thick and full as before the treatment
