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.
Minoxidil (UK)/ Rogaine (US)
A truly market tested product Minoxidil has saved the hair of countless men and women. It was approved by the FDA in 1988 as the first topical treatment proven to show re-growth. The approval was based on the results of a large study of 1800 men taken over a year. It would take nearly another decade for the approval to come through so women could benefit too.
In its modern form it is a simple, rapidly absorbed mousse that needs to be applied twice a day. Because it acts completely differently to Finasteride, the two treatments are often recommended as part of a treatment course.
Caffeine has been shown to reach the roots of hair follicles, where it can protect against harmful DHT in a similar way to Finasteride. So while it yet to be medically approved as a hair loss product, there is little doubt within the industry that it is of great importance as a weapon the fight to resist further loss.
