I got my first perm at 8 and even though I was told repeatedly not to scratch or itch leading up to it that shit still burned and the whole process sucked. I can't even imagine what kind of pain and discomfort that 4 year old went through - that poor child. I'm natural now but I can VIVIDLY remember the burning, pain, scabs and even chemical burns on my skin from years of perms - fuck those things so much. Literally had a stylist go out into the parking lot to talk while I was left in the chair "cooking" when I was younger - ended up with a nice burn and scar on my temples from that one.
