• Cell turnover acceleration - Dramatically accelerated skin cell production and  shedding , multiple times faster than the normal rate.

• Barrier dysfunction - Severely compromised skin barrier

•  that loses moisture easily and remains dry and vulnerable.

• Microbiome changes - Altered scalp microbiome in affected areas

• Genetic factors - Strong hereditary component

Triggers and Aggravating Factors
