Ontrigger issue with GUI label

Hi, I am trying to get a GUI text label to display upon the OnTriggerEnter function event. However, It appears that when I start the game the text for this label is already being displayed instead of only appearing once the trigger collision has initiated. Below is the code I have used, as we can see I have used a boolean to try to trigger when I wish to have the GUI text label displayed.

   // public Transform currentCheckpoint;
    public bool TextLose = false;
 
 
     void Update()
     {
         if (TextLose == true)
         {
             OnGUI();
         }
     }
 
     void OnTriggerEnter2D(Collider2D target)
     {
         if (target.tag == "Laser")
         {
             TextLose = true;
         }
    }
 
     void OnGUI()
     {
         GUI.Label(new Rect(10, 10, 100, 20), "You lose!");
     }
 
 }

Any suggestions on how I can get the text to only display when the collision happens?
