I don't know your issues so I can't answer if something may or may not work for you. I can tell you what works for me and I am older than you.
I've never had issues with hair loss. I do have issues with my blood and absorption and I am one who will only take an RX if it is extremely necessary.
That said, last year I had some bone issues in my ankle and tried a new procedure that stimulated stem cells to make the bone grow back. It is called Platelet Rich Plasma and as of right now, it has worked well. It is not FDA or insurance approved but many pro athletes do this with success.
For YEARS, I have taken a sublingual B-12 3000mg daily ( I used to get B-12 injections), along with sublingual D 5000mg, Biotin 5000 mg and vitamin C 2000 mg per day. I have not heard negative things about Biotin but I do not get online and google health issues because there is so much hype out there you don't know what to believe and then you start thinking you have whatever bad ailment the computer is telling you about... I stay away from that.
At my last visit about 3 weeks ago, I started 1800mg of Curcumin daily. Also called Tumeric. The Curcumin is a natural anti inflammatory and pretty new for me, but so far I have no pain in my ankle joint and my Dr. believe it is helping me keep gout at bay. It replaces a new RX Zipzor I was on that was a very mild dose in order to aid with ankle.
I see my bone Dr and an endocrinologist and have blood work done routinely to make sure all is in order. Sometimes they ramp up my Vitamin D to 10,000mg a day for a couple of weeks or so. Many years ago, they were sure I had leukemia and I ended up with complete hysterectomy which was the best thing I ever did for myself and my blood cleared up after that with exception of absorption.
Find a Dr who will listen to you and work with you to find the best solutions. I've heard about shampoos that help reduce hair loss but I think once you start them, you have to stay on them. Nioxin is one I have heard about.
Best wishes to you.
