First-line drug treatments for androgenetic alopecia (common alopecia) include 5-alpha reductase inhibitors (Finasteride and Dutasteride) and Minoxidil. These are treatments that are administered systemically/ orally.
In the case of dutasteride, it can be administered as microinjections into the scalp. This is known as hair mesotherapy. This technique has been identified by several scientific studies as an effective therapy to slow down the evolution of androgenetic alopecia (see references).
This hair mesotherapy technique attempts to obtain similar results to those achieved with the aforementioned oral 5-alpha reductase inhibitors, but minimising their adverse effects. In addition, Dutasteride injections increase the patient’s follow-up of the treatment because of their convenience: injections can be monthly, bimonthly, quarterly or even every four months, instead of having to use the drugs daily.
