Hi, dear I have gone through your question. I can understand your concern. You have hypothyroidism and hair fall is a very common symptom of hypothyroidism. Many patients may not improve in hair fall even after thyroid hormone replacement therapy. In that case minoxidyl ointment can be used. It is safe when used in hypothyroidism. It should be avoided in pregnancy and child bearing age. Significant improvement take a long times with minoxidyl. So don t worry. It will take time. Continue daily use of minoxidyl. Check your TSH also because sometimes under treated thyroid may be the reason. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
