What is the best medicine to stop hair loss and regrow hair?

There are many medications available for treating hair loss. Unfortunately, these medications are expensive and may not work for everyone. Therefore it is difficult to recommend any one as the "best". A physician should be consulted to determine if your hair loss is caused by disease, genetics, injury, or aging. Your medical history will be assessed and any dietary or hairstyling habits that may be affecting your hair or scalp will be considered. Tests may be done to rule out any diseases or infections that may be contributing to your hair loss. Treatment will then be based on these medical findings, and may or may not include use of prescription or OTC medications.
