Actually when you are using one brand of hair fall shampoo, then you must not change it everyday or months lar, you need to be patient a bit to get the result. One thing a lot of people don't know that not enough sleep will also cause hair thinning, people used to sleep very late, like 2-3, even 4am, then you will have the greater chance of getting hair thinning problem. You at least must sleep 7 hours a day, and also need to follow the "sun rise & sun set" method.
