C# While loop not working as intended

I have this boss battle in my game that i'm working on for a class and its not working as intended, after the boss or the player dies it prints all sorts of attack and the death messages.

Im pretty new to code, just started this year for a class

Thanks in advance!

Here is the boss battle:

public static void redKeeperBattle()
    {
            if (boss.redKeeperHealth <= 0 && (player.playerHealth <= 0))
            {
                Console.Write("You have defeated ");
                Console.ForegroundColor = ConsoleColor.Red;
                Console.WriteLine("The Red Keeper!");
                Console.ResetColor();
                Console.ReadLine();
                Console.Write("But you have also ");
                Console.ForegroundColor = ConsoleColor.Red;
                Console.WriteLine("Died!");
                Console.ResetColor();
                Console.ReadLine();
                playerDeath();
            }

            if (player.playerHealth <= 0)
            {

                boss.redKeeperAlive = false;
                Console.ForegroundColor = ConsoleColor.Red;
                Console.Write("The Red Keeper ");
                Console.ResetColor();
                Console.WriteLine("has killed {0}, how sad...", player.playerName);
                Console.ReadLine();
                playerDeath();
            }

            if (boss.redKeeperHealth <= 0)
            {
                boss.redKeeperAlive = false;
                Console.Write("You have defeated ");
                Console.ForegroundColor = ConsoleColor.Red;
                Console.WriteLine("The Red Keeper!");
                Console.ResetColor();

                Random pDodge = new Random();

So what happens is when someone dies it just spams messages like:

You hit The Red Keeper for 12 Press Enter to end your turn...

The Red Keeper hit you for 14 Press Enter to end his turn...

You have defeated The Red Keeper!

The boss has died!

An error occurred! Please try again! Press Enter to continue...

You have defeated The Red Keeper!

The boss has died!

You hit The Red Keeper for 29 Press Enter to end your turn...

The Red Keeper hit you for 19 Press Enter to end his turn...

You have defeated The Red Keeper!

But you have also Died!

You have Died!
