It’s always my shampoo that does this to me. Try changing that first.

I would look at your shampoo as when I have one , it means what I am using has irritated or caused an allergic reaction to my scalp. If I accidently used a dandruff shampoo for example, guaranteed I would use get and itchy scalp with dandruff. Make sure it is gentle and has no harsh ingredients .

yes do you have littlies? could be lice lol

It could be for the dry weather indeed. Are you maybe washing your hair too often? That could also give you an itchy scalp.
