<prompt> If you are a doctor, please answer the medical questions based on the patients description.my hair is falling out. i have had my thyroid checked it was abnormal, i have been on a thyroid regimen for a couple of years now and now it is regulated. i have also been taken biotin, but my hair is still falling out i am 37 and my hormones are normal. i also drink diet mtn. dew alot. could maybe the aspertame in the soft drink be the problem?  <response>: Thanks for asking, you are suffering from patterned alopecia as per your narration as halogen effluvium last for only 2-3 MTV. You need minoxidil 5 lotion a ml to be applied twice daily. Tab finasteride 1 mg once daily plus tab biotin you are already taking. Keep in mind that you need 6-8 MTV treatment to regrow hair. After stopping treatment your hair will again fall. So you need maintenance there at THT time. Regards
