Living with Alopecia universalis congenita

A condition with complete loss of hair on the scalp and body, which can be present from birth.

Understanding Alopecia universalis congenita

Alopecia universalis congenita is a condition with complete loss of hair on the scalp and body.

Alopecia universalis (AU) is an advanced form of alopecia areata, which causes round patches of hair loss. It can start at any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Complete loss of scalp and body hair
  • Missing eyebrows
  • Missing eyelashes
  • Patchy hair loss

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in HR are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Autoimmune Association and National Alopecia Areata Foundation may keep lists of experts for this condition.
