alopecia
"IT WORKS, I am 21. You may have hair fall at the starting stage but it may be a good sign because you are gaining new hair strands losing the older one. I saw the improvement within 3 weeks, I was losing less hair than before. 
Just apply twice a day, remember don't let it spread over parts other than your scalp. Apply before about 2 hours before you go to bed at night, let your scalp dry first. Shampoo before you apply (not every time) and let it dry. And it will work best then. But get familiar with it's side effects too. I don't know about others but yes I am developing dark circles around my eyes since the day I started applying it."
