Also are you referring to Male Pattern Baldness? Which NW scale are you at right now?
Statements below in reference to MPB only.

- MPB primarily caused by scalp follicle sensitivity to DHT
- Finasteride and Dutasteride, which is originally used to treat BPH, has been shown to reduce serum DHT
- Minoxidil has been shown to be able to trigger growth phase in the hair follicles

This being Malaysia, if you really know what you're doing, just walk into any big chain pharmacy and ask for it.
- oral minox 5mg is about rm52 for 30 tablets at your local major chain pharmacy, can start at 2.5mg by cutting it
- Dutasteride 0.5mg is about rm114 for 30 tablets
- Finasteride comes in 1mg and 5mg pills, usually ppl will buy the 5mg and cut, cant remember the price but its alot cheaper than DUT
