Agree that you look good in both pics. I'll just take your word for it that your hair and brows have improved because I can't really tell the difference in the "after" pic. I like your avatar pic.
My hair and brows have definitely improved, I guess I had some degree of hypo T previously because I did experience the thinning of the outer brows that you describe. All is well now.
I recommend gelatin as well as Iodine for better hair/skin etc. Here are some links.
