no it does not contain minoxidil or any such kind of chemical. It uses natural medical synergy to help inflammation of the scalp which is why it can possibly help with hair problems – that said, you should take collagen supplements (beef based) and detox your liver by taking stinging nettle once a day (supplements).
why would you think they add minoxidil in the soap, minoxidil is probably the biggest scam in medical history that I know of, as it temporarily helps hair, and then it kills hair after some time. They def do not use this drug in their soap.
