Pili pseudoannulati

Pili pseudoannulati (pronunciation: pee-lee soo-doh-an-yoo-lah-tee) is a rare, benign hair disorder characterized by alternating bright and dark bands along the hair shaft when viewed under polarized light. The term is derived from Latin, with "pili" meaning "hair", and "pseudoannulati" meaning "false rings".

Symptoms

The primary symptom of pili pseudoannulati is the appearance of the hair. The hair appears to have alternating light and dark bands, which can be seen under polarized light. This is due to the irregular reflection of light from the hair shaft. The hair itself is not structurally different from normal hair and does not have any additional health implications.

Causes

The exact cause of pili pseudoannulati is unknown. It is thought to be a genetic condition, as it often appears in families. However, the specific genes involved have not been identified.

Diagnosis

Diagnosis of pili pseudoannulati is typically made through visual examination of the hair under polarized light. The characteristic banding pattern is usually sufficient to make a diagnosis. In some cases, a hair shaft analysis may be performed to confirm the diagnosis.

Treatment

There is currently no cure for pili pseudoannulati. Treatment is typically focused on managing the appearance of the hair. This may include the use of certain hair care products or styling techniques.
