I've let it grow for about 5 days and I was amazed at how much hair I have lost. I stopped using Rogaine, when I starting shaving my head. I was not comfortable putting chemicals on my scalp anymore and I had accepted being bald. I would never ever recommend Rogaine to anyone, but I must say that it did work. Once I stopped using it, my bald spot accelerated very very quickly. Sure is a good thing that I like my melon smooth.
