Halacha and male grooming

Hello Rabbi Michi
In our day and age, when the culture of beauty and grooming exists to a large extent among men (mainly secular, but not only), would it be permissible for a man to remove body hair, dye his hair white, groom his eyebrows, etc.?
If so, then it follows that the law can change due to the behavior and actions of those who do not consider it or do not follow it. Isn’t there a certain paradox here?
