Aah OK didn't realise on both counts

You could get Rogaine/Regaine hair treatment, it reduces the effects of DHT, it's a topical solution and in some countries, like here in Australia, you get it over the counter.
Can you see your own GP for the Finesteride? It will dramatically reduce DHT on its own, but it does cause boob budding and reduced male libido... I am guessing that is not a problem

Although when your GP explains that they may probe the loss of maleness

Hope that helps
