I used a lice comb and found a bunch of white sharp things in the comb from my scalp. There were hundreds of them.
I called my sister and she said they could be keratin horns. I called the hospital and they said it sounds like they could be keratin horns. Can people get hundreds of keratin horns? They are known to be cancerous. I cleaned them all out of my hair. The nurse on the phone told me to wait til they grow back and save them and give them to a dermatologist
