I can tell everyone who has the problem of hair loss here, there's only one treatment which is approved by the United States FDA and is recommended by all doctors. And most magazine survery by readers agrees. The name is called 'Regaine'. You can buy it everywhere. There are 2 different treatments, one for woman and the other for man.
You can just massage onto your head and I think 1 bottle can be used for around 1 month. I suggested this to many people who have tried all different methods and wasted much money. They all said it works.
But please note that your gained hair will be lost again if you stop to use it about 1 month.
