Thankfully I have good shaped head.
There's some slight thinning on top, front looks good, and still looks good longer but I rather just get it over with and shave it.
I do use minoxidil though, though don't know how much of a difference it really makes.
For awhile I was using a Saw Palmetto/Pumpkin Seed Extract combo and I think it did thicken my hair but I noticed more weight around my mid-section despite training hard and not eating badly and felt like my strength was down. Couldn't pin it on anything else except that, so I stopped and physically improved a lot after that, and my training recovered.
Considering that it's about 40% as strong as finasteride, that's out of the question for me. Also when I tried finasteride for over a month my nipples started hurting like crazy.
Wrecking my male hormones to save my hair doesn't seem worth it, but some others might not have any major side effects or they're at least mentally OK with these effects.
