You don’t want psoriasis. I’ve had it behind my ears since I was 6, and it has never ever gone away. No moisturiser, steroid cream, or change of hair routine has had an effect on it. It comes and goes, recedes and spreads, according to its own will and desire.

It’s probably the weather or stress that has caused your skin dryness. I’ve heard that having a hot shower as normal and then before you get out turn off the hot water and run yourself under the cold, can help as well. Hair dryers also cause damage from what I understand.
