Can we apply 'Minoxidil' on scalp or face to get proper scalp or beard hair?

Minoxidil contains alcohol (synthetic), also we r not consuming, just applying. So, is it allowed? Some people say that because it is synthetic alcohol which is made by chemical, not natural alcohol, so it is OK. Also, we are not consuming, we are just applying on body, so it is fine. Other people say that even though it is synthetic and we are just applying, still it is haraam, and also by trying to modify your looks by doing this, you are Nauzubillah challenging Allah that I do not like the way you have made me and I am changing it. So it is not allowed. Can you please let us know whether this is allowed or no?
