I have been having heavy hair fall since last 8 months. I didn't notice it for first 4 months and then I went to doctor. He gave me minoxidil 5% and other medicine. My vitamin D deficiency was also there, Which is cured through medication. Now, I have thicker and stronger hair than earlier but if I stop using minoxidil even for a day, hair fall at same rate. I do not understand what I have got to do to get back to my better hairs.
