Propecia is oral base medication. Not cheap becoz the patent not yet expired. Works for some but not for all
Minioxil 5% or more is cheaper, probably patent expired. Likewise works for some not for all. Becareful when u use.... some people spray all over the head and then go to bed and roll about their pillow. Next thing they realise hair start growing all over their face instead of thir scalp.
If all things don't work....... go bald lor. See my user name you'll know oledy.
Whatever it is... pls don't do leave long hair at the side and then do the "big sweep" over cover the spot hair style. Sibei pai kua!!!
