Sherry is sleepy

I am feeling very hot and I just have my hair washed. I had my shower first but did not wash my hair. I cannot stand the itchy feeling and I went to get my hair washed.

Not sure if there is any dandruff problem. I do not have this feeling before maybe it is a sign that my period is coming soon.

Everyone has a signal or sign and I believe not everyone the same. You are free to tell me yours.
