A user found out they are vitamin D deficient and was prescribed high-dose vitamin D supplements, asking if others had similar experiences and if it improved their hair. Some shared improved mood and testosterone levels after treatment, while another combined vitamin D supplements with finasteride due to family history of baldness.
The user stopped using minoxidil and vitamins for three months and noticed no change in hair loss. It suggests they might be a non-responder to minoxidil, but finasteride could still be effective.
