Just to share : Been on minoxidil for about a year and a half and have not seen even the smallest amount of regrowth that i almost fell into depression.
My hair only started visibly growing after doubtfully trying out the various natural techniques to re-grow lost hair @ http://www.regrowmyhair.info
I would highly recommend this easy to follow step-by-step guide with pictures to anyone who is suffering from hair loss right now.
Anyway, its also a cheaper and effective way of re-growing lost hair compared to those unnatural ways which may involve harsh chemicals that may have side effects.
