Nothing, just that. My pikachu is awesome. Like a boss.
Also, I discovered that non-heat resistant wigs actually resist heat. Seriously. If your iron is good and straightens fast your hair, it'll probably melt your wig. However, kanekalon wigs can resist up to 90 - 100 degrees Celsius. Really.
I'm saying this because before trying it, I was deadly scared of even combing my wig. Now, I fear nothing. Oh, boy.
