Bfs hair insecurity

Hi everyone! So I adore my bf, we have been together for a while and I know he is insecure about his genetic hair loss. Every man in his family looses hair very young. We are in our very early 20s but it has always bothered him and he hasn’t been able to fully come to terms with it. Obviously I have assured him that I would love him no matter what he looked like or how much hair he had, and that makes him happy. But he has told me that he briefly tried products but nothing helped. I was wondering if anyone had any product recommendations? I obviously want him to fully accept himself first and be confident in his appearance ( especially since it will happen to all of us someday!) but I’m curious if anyone has had a great experience with a product! ( I may in the far future gently and kindly bring it up as an option if he comes to me in search of an product)

❤️ thanks guys!
