I hesitated on starting it due to it being a long term commitment. Then I finally took the chance. I hit the shed about 1 month in. I didn't see any regrowth for about 3-4 months. And now there's patches of course hair growing in everywhere. I had a haircut tonight and she told me it was quite unbelievable the amount of new hair growing. I've noticed it at the hairline (not heaps yet) but I couldn't see the crown, I don't have a bald spot but it was thinning quite alot. And now according to her I have heaps growing in at the back, all very short at the moment but she said it was quite course looking and its pigmented. So I definitely think it's worth at least trying.
