Question Have you heard of Aminexil? Does it work?
Answer: Aminexil is a patented chemical molecule developed by L’Oreal and is claimed to help prevent perifollicular fibrosis (scarring of the hair follicles) that has been heavily promoted as a treatment for hair loss. The company did come under a bit of fire about that because they’re a cosmetic company and not a pharmaceutical one. Still, aminexil is found in quite a few topical hair loss products, none of which have been proven or licensed for the treatment or prevention of hair loss.
Even after 15 years of independent research, aminexil is not a licensed treatment for hair loss because any medical product must have regulatory approval (such as from the MHRA (UK) or FDA (USA)) before it’s considered a safe and effective treatment. To get a medical license the manufacturer must conduct a scientific study that is statistically relevant and it must meet all of the clinical research regulations published by the regulatory bodies. Currently, there are only two products that have been licensed for the prevention of hair loss by both the MHRA and the FDA, and aminexil is not one of them.
Aminexil is said to work in a similar way to the proven hair loss treatment minoxidil. However, aminexil is often mixed with minoxidil and if it was to work to any degree it’s likely to be the minoxidil that helps and not the aminexil.
That’s not to say using aminexil will have no benefit – there isn’t any evidence to say that it doesn’t work. However, there’s also no conclusive evidence to say that it does.
