Heal player on loading scene

Hi, I’m making FPS game and I need to heal player on loading scene. Always, when the game loads next scene, it saves the health from the previous scene instead of healing the player to max health.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class GlobalHealth : MonoBehaviour {

	public static int PlayerHealth = 100;
	public int InternalHealth;
	public GameObject HealthDisplay;

	void Update () {
		InternalHealth = PlayerHealth;
		HealthDisplay.GetComponent<Text>().text = PlayerHealth + "/100";
		if (PlayerHealth <= 0) {
			SceneManager.LoadScene (0);
		}
	}
}

if (PlayerHealth <= 0) {
PlayerHealth=100;
SceneManager.LoadScene (0);
}

you just set it before you load the scene.
