Male pattern baldness cannot be cured as in stop the balding and then the hair will regrow.
Unless its stress related or caused by an underlying disease then it can be cured and hair will regrow.

Stop it at its tracks before it gets any worse. You can save it as it is but u can never have a full head of head like u did prior to your balding. If want more hair have to go for hair transplant or the good old wig. Those are pricey though.
