I agree, it really takes one full year to make a fair evaluation and then it should be facilitated with the use of a digital microscope with an integrated camera. These are the newer Carson USB scopes that can download the images into your computer for comparison purposes. This is the sure way to know if the patient is stabilizing or continuing to lose hair within a defined surface area.
The magnification is up to 35X and also has a built in illuminator. The resolution is up to 640x480. They onlu cost $39.99 US. The 6 ft cable is only $2.97 US and can be purchased online from Radio Shack.
If you are still losing hair after one year of close comparisons, and also following the big 3 meds as directed, I would recommend that you buzz your head for now.
