Character Selection

Hello! I created a few characters, in which I'd like the player to choose from, I created a script which will allow the player to "scroll" through the characters using the right arrow, however, I am only able to scroll once, before it stops working.

My script is most likely very poorly made, I am rather new with C#, I put all the characters at the same location, and set them inactive, except for the first one. I made an if statement, detecting if a character was active, and the arrow has been pushed, then it will shuffle to the next character. This however didn't work, is there a better way?

Here is the Script: (Sorry for the mess)

 using UnityEngine;
 using System.Collections;
 
 public class CharacterSelection : MonoBehaviour {
 
     public GameObject BlackHairBlueShirtBluePants;
     public GameObject BlackHairBlueShirtGreyPants;
     public GameObject BlondeHairBlueShirtBluePants;
     public GameObject BlondeHairBlueShirtGreyPants;
     public GameObject BrownHairBlueShirtBluePants;
     public GameObject BrownHairBlueShirtGreyPants;
 
     public bool hair;
     public bool shirt;
     public bool pants;
 
     void Start () {
         BlackHairBlueShirtBluePants.SetActive(true);
         BlackHairBlueShirtGreyPants.SetActive(false);

         BlondeHairBlueShirtGreyPants.SetActive(false);
         BrownHairBlueShirtBluePants.SetActive(false);
         BrownHairBlueShirtGreyPants.SetActive(false);
         hair = true;
     }
     void Update()
     {
         hair = true;
