I've also been using this for about a month. I haven't noticed any regrowth, but I've noticed a slight reduction in shedding. Nothing major, but definitely noticeable, which is pretty significant for me since I shed alot daily and nothing else I've tried worked, including finasteride. Actually, fluridil (topilutamide), which is another topical anti androgen I've been using, helped reduce shedding by a little bit, but I feel the oh flut has been slightly more effective. I think this stuff is definitely doing something, I'm going to buy a few more months supply and see where this goes. I'm only using the topical oh flut and discontinued the fluridil when I started the oh flut.
