Living with Uncombable hair syndrome

A condition in which scalp hair is dry, frizzy, and stands out in all directions, and usually improves with time.

Understanding Uncombable hair syndrome

Uncombable hair syndrome is a condition in which dry, frizzy scalp hair cannot be combed flat.

It develops in childhood, often between infancy and age 3, but can appear as late as age 12. The hair is light, blond or silvery with a sheen, and grows out in many directions. The hair is not fragile or brittle. Only scalp hair is affected. For unknown reasons, it usually improves over time, and by adolescence hair lies flat with a normal or nearly normal texture.

Signs & symptoms

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

  • Dry, frizzy hair that can't be combed flat
  • Blond or silvery hair with a sheen
  • Hair that grows out in many directions
  • Coarse or woolly hair
  • Hair that grows normally or a little slowly

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.

  4. Connect with expert centers

    National Foundation for Ectodermal Dysplasias may keep lists of experts for this condition.
