According to the American Hair Loss Association (American Hair Loss Assotiation www.americanhairloss.org) people with hair loss spend more than $ 3.5 billion a year on medical treatments, of which 99% are ineffective; that’s just speaking of North America. To avoid being a victim of this “hair loss treatment industry” that is generally unethical and often misleading, we recommend that you do not buy drugs or treatments that are not approved by the FDA (Food and Drugs Administration) or failing that. by the EFSA (European Foos Safety Authority).
