The sad truth about hair loss with age is that it is programmed if the guy's genes are like that. No amount of ingesting tablets or applying hair medication can help stop it. Otherwise the very rich celebrities would have paid top money to save their hair.
Don't even bother with all those hair salon shops, eg normal salons or the notorious Beijing 1*1, Yun*an, etc. They are good to clean your hair (which you can do on your own also!) but they won't work if your genes predispose you to hair loss.
Think about it: You also only go there like once a week or once every few weeks and the sessions are not cheap. How are those few treatments per month going to help anyway when your hormones that cause hair loss work on your body 24/7?
Minoxidil might work for only some men but even then, it's a little help only. Only helpful for top part of head Same as Fines though some say it's more effective but it comes with some side effects on male fertility.
Many of the Before and After photos selling hair tonics are either edited (Fake!) or they comb the hair in such a way to make it seem the hair has grown more.
