Living with Loose anagen hair syndrome

A harmless hair condition in children in which hair can be pulled out easily and painlessly.

Understanding Loose anagen hair syndrome

Loose anagen hair syndrome is a rare, benign hair disorder in which hair can be easily and painlessly pulled out.

It mostly affects blond girls in childhood. Most hairs are in the growing (anagen) phase and lack an outer sheath. Hair grows back quickly, and the condition improves on its own with age. It can sometimes occur with other differences, such as coloboma.

Signs & symptoms

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

  • Hair that pulls out easily and painlessly
  • Changes in hair structure
  • Unusual hair whorl
  • Coloboma of the iris (cat eye)

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. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
