24 year-old male diagnosed with low testosterone - should I take 5mg Finasteride?

First, finasteride is not an option for men with a thick head of hair. It’s an option for males with aggressive balding. If a male does not have AGA, they should not be on finasteride to prevent AGA. That’s where problems arise time and time again. Second, I need to know how low your testosterone is. I need to know your bioavailable testosterone. Many males who tell me they have low T, don’t have low T. But be sure to see an endocrinologist if you do. One needs to understand why that is. If you are having side effects on finasteride, you need to speak to your doctors. That dose probably won’t help much. However you have many options if you do have AGA including topical finasteride, topical minoxidil and oral minoxidil.
