Balding runs in my family, and I'm thinning out at the top at 27. Should I do a trial buzz to make the top even with the sides?

Wearing my hair in this style is the only way to cover it up. If I let the top get any longer than this, it becomes super obvious how thin it is. I have no deep attachment to my hair, and used to wear a beanie almost full time due to feeling weird about it since It started thinning 5 years ago at 22.
