My 13 yr old daughter her has lost almost all her hair in a matter of a month, finally shaved the last bits off a week ago. We used a trimmer, set to a number 1. But now she has developed a ton of little red pimple/bumps (looks like heat rash?) all over her head. Even though she goes bald (no wig) and she has it both in the spots where there is still a little stubble and in the bald patches. What's up? Any ideas what is going on? She doesn't want to go back to the dermatologist who was terrible- totally insensitive. And she is not using any of the treatments. Has any one had this? What to do?
