I know you're directing this question to Amneris, but I wanted to add my 2 cents.
My mother pressed my hair from around ages 8-13. She used one of the old school hot combs that have a slight curve to it, so that you can get the roots nice and smooth.
I didn't have any bad experiences when she did this, but when she would get to the back of my neck and around my ears, I had to make sure that I was completely still so that she wouldn't burn me. I can probably count on one hand the times I was slightly burnt. Luckily I never had to walk around with those burn marks that people would get on the ears. As soon as you see it, you know that someone burnt them with a hot comb.
