Male Baldness Info

does the nioxin shampoo stop thinning and male pattern baldness. does it stop or slow down a receding hairline?
also, my hair used to be very thick at my crown but it has recently started to thin. will nioxin make that hair as thick as it used to be by cleaning my scalp and follicles?

will nioxin stop or atleast slow down male pattern baldness ie receding hair line and thinning crown?
will it help me retain the hair i already have?
