Bests & Worsts Reviews from Amazon

I started using this as an 18 year old who noticed thinning in the crown area. It wasn't to the point of being highly noticeable by anyone--just slightly thin if I ran my hand through it. Still, I thought Rogaine would be a good option to reverse my thinning and preempt further loss. So I applied it religiously for four months. What made me stop? After months 3 or 4 I practically had a reverse yamakah! I'd say the crown area had 30 to 40% of the hair a full, healthy head would have. Now, I know that supposedly there is an initial shedding phase with Rogaine and then hair grows back, but I had already reached the 4 month mark where regrowth should be apparent, yet it wasn't. How much longer was I going to apply this chemical concoction to my hair hoping its effects do a complete about-face and actually start regrowing my hair? So I stopped. Now a year later, my crown is still just as thin as when I threw out the Rogaine. Lesson learned: think before you gamble on things like this.
