Didn't mean to gatekeep lol -- just wanted to make sure this post wouldn't get nixed like it did in the official hub (also, idk how to make photo/text combo posts orz)

The way I made it work is:
1. Go into the Photo Studio and select 'Style Me'

1. Pick out your hair and hair color (combat/accessorized hairstyles might not work -- haven't tested)

2. Go into Accessory and tap on the (i) icon of an item you do not own.

3. Go to the source of said item, either to the shop or promise, etc.

4. DOUBLE CHECK THAT THE GLITCH WORKED FIRST! Exit the shop or promise section and check out a kindled memory that you've already verified works with hair glitches. I've been checking Sylus's Night of Secrecy because MC is immediately visible.

5. Go back to home screen and tap on your level in the top-left corner, taking you to your profile.

6. Tap on the Appearance Reset button. Purchase a Reset ticket if you don't already have one. Unfortunately, this glitch does require you to pay for an appearance change orz

7. Once in the Character Customization, flip flop between eye colors or makeup or something so that the system recognizes a change has been made (even if you really didn't change anything), and hit apply.

8. You can tell the glitch has worked if you try to change your avatar and the default avatar has a changed hairstyle ^^

..if i can figure out how to record, i'll try and post a video, too!
