Nioxin System 1 was recommended to me by my hairdresser.  I am in my mid-late forties and have natural gray hair that is thinning quite a bit on top.  All the females in my immediate family are struggling with this problem.  I have used Rogaine for Women for over five years and really have not noticed much difference except I do not lode as much hair as i used to.  I have been using the Nioxin System 1 for six months and can notice quite a difference.  I seem to be losing fewer hairs and my hair looks thicker, shinier and much more luxurious.  I use the shampoo and scalp therapy (conditioner)...
