Minoxidil after HT, return to working out

[KingTekken]

I had my HT 6 weeks ago and my consultant suggested that I use minoxidil and Fin. I'm 47 years old and cautious about them. I box and practise mma which are high impact. I have a few question. 

What's the benefit of minoxidil after hair transplant? Do I really need it, the minoxidil I bought said up to 49 years old in the instructions. Would I grow hair on my body. I have no hair at all on my body and prefer it this way. I don't want to get on Fin because of it having an effect on my erection.

It's 6 weeks now, surely I can return to my sport. I sweat a lot, can this affect anything?  I can deal with another 2 weeks of waiting to workout but anything longer I'll lose my mind. 

Thanks,  I'm sure these questions have been asked over and over again.

Don't knock it till you try it. The vast vast vast majority of guys have zero sides. 

Minoxidil/Rogaine does nothing IMO.

Be willing to try finasteride because most men take it with no negative side effects. 3 mg/week. 

Minoxidil is a topical agent that increases blood flow to the scalp and helps hair grow stronger and thicker. Once a day rub in. No age worries. 

Yes you can fully return to your sport at this point.
