If I used someones flat iron, and she had stuff eating at her scalp that she often scratched, am I doomed too? I looked up something online and it said that it is a fungus, the same one that makes the ringworm one, which is the same that makes athlete's foot. Her symptoms were on the page. "Hair is destroyed, leaving bald patches." under Tinea capitis. She thinks it's missing because of her scratching there, but it looked like her scalp was being eaten away. All around where the fine hairs of her head would be.
I hope I don't get that, all I did was use her crimping iron. I tried to clean it off with a soapy wash cloth when she went down the stairs, and it was still on too. But I didn't think about the comb or brush, 'cause when she came back, she used them on me

plus, I rushed with my perm and mixed the conditioner with the cream product, instead of the activator. I ended up never using that activator. I just didn't have a true perm. My head's still tingly though some, I hope my hair doesn't just fall out.

Then I'll be baldheaded with a fungal infection.

Summarized question: Can you spread a fungal scalp infection by using the same hair styling tools like a flat iron?
