Approved by the FDA in the US and NICE in the UK, who both class it as a “5-alpha reductase inhibitor”. This inhibits the further build-up of Di-Hydro Testoserone (DHT), which can be a key factor in the development of hair loss. DHT is of no use to an adult, it is a redundant function left over from puberty that doesn’t turn off fully. Over time, its build-up can present as hair loss in men.
It comes in the form of a tablet which, taken daily, has the potential to halt further hair loss in its tracks.
