The first time she got it was a few months ago, it started off with a severe
itchy scalp and red
itchy spots on her neck/back, then she woke up with a shock, her scalp was covered in yellow crust, it was awful she was so distressed, i had to get it out with a nit comb. That time she was suffering from stress.
Now once again it's happening, the weather here in England has been 30c and she works in a School kitchen with no air con so you can imagine how hot it is for her.
