I wish I had taken before and after pictures, but minoxidil has helped me a lot. I've been on it for about 6 months now (Kirkland 5%) and I started seeing good results after about 2 months. I've grown a lot of hair with it. Thicker all over the top and the crown. Hasn't done anything for the widows peak---at least not yet--but I'm not too concerned about that. No itching. I went from about a scale 2-3 to 1-2. I've had a lot of compliments about my 'haircut'. I don't bother to tell people it's the same haircut I've always had.
I spend probably less than a minute putting it on twice a day. My only concern, at this point, is how long will it last? I know it stops being effective eventually but will it be in 6 months? 2 years? 10 years? I've heard varying stories. If it starts to lose effectiveness, I'll look into Propecia, but I'd rather not deal with the needed prescription and possible side-effects if I don't have to.
I guess it works for some people better than others. If I didn't see any effects after the initial 4 months supply ran out, I would have stopped trying it.
Good luck!
