30 year old male. Have noticied more hair coming out while combing and shampooing. Hair still pretty dense with very minor bit of hairline recession. Tips to hold off any balding before too late?

Like the title says, looking to prevent hair loss before it's too late. I have pretty thick hair but have noticed more hair on my hands when I shampoo and comb. Any tips short of prescription stuff I can do to make sure my hair stays where it is?

I style with pomade nearly every day, only shampoo twice a week or so. Usually it's an anti-dandruff shampoo like Nizoral but I try to restrict my use of it.
