I did a couple years ago. I am 48 and it's in the genes for me to have diffuse thinning along with my age. It didn't do anything for me after a few months trial. For those of us who have diffuse thinning there really isn't much you can do to stop it. I even tried Rogaine for a year and nothing. It grew hair on my face! If anyone finds anything that helps with diffuse thinning caused by age/genes, let me know!
