Can i increase my height upto 6inches in a month?

No: Your height is predetermined by your genes.

Impossible dream.: A few inches is. Attainable but not 6 inches unless there's divine intervention or u get struck by a lightning. Best wishes! http://m.Wikihow.Com/grow-taller.

High heals: At 17 your linear growth centers are likely closed, so you need to accept your height. If you want to appear taller, high heals can give you a temporary boost, but I find them unhealthy for the long term.
