Uncombable hair syndrome
Uncombable Hair Syndrome
Uncombable hair syndrome (pronunciation: un-kom-buh-buhl hair sin-drohm), also known as spun-glass hair syndrome, pili trianguli et canaliculi, or cheveux incoiffables, is a rare structural anomaly of the hair.
Etymology
The term "Uncombable hair syndrome" is derived from the characteristic feature of the condition where the hair is impossible to comb flat. The other names for the syndrome also describe its features. "Spun-glass hair" refers to the hair's shiny and glass-like appearance, "pili trianguli et canaliculi" describes the triangular shape and grooved structure of the hair shaft under a microscope, and "cheveux incoiffables" is French for "unmanageable hair".
Definition
Uncombable hair syndrome is a rare congenital condition characterized by silvery-blond or straw-colored hair that stands away from the scalp and cannot be combed flat. It is usually recognized in childhood and may improve over time.
Symptoms
The primary symptom of uncombable hair syndrome is the presence of dry, frizzy hair that cannot be combed flat. The hair may be described as being spun-glass or straw-like in texture. Other symptoms may include slow hair growth and hair loss.
Causes
Uncombable hair syndrome is caused by mutations in the PADI3, TGM3, and TCHH genes. These genes are involved in the formation of the hair shaft. The condition is inherited in an autosomal recessive pattern.
Diagnosis
Diagnosis of uncombable hair syndrome is based on the characteristic appearance of the hair. A microscopic examination of the hair shaft may reveal triangular cross-sections and longitudinal grooving, which are characteristic of the condition.
Treatment
There is no cure for uncombable hair syndrome. Treatment is focused on managing the symptoms and may include the use of conditioners and softening agents to improve the hair's texture.
