The bifurcation can occur at any point along the length of the hair shaft and may be multiple. The hair is often brittle and breaks easily. The condition is usually isolated but can be associated with other hair shaft disorders.

Diagnosis

The diagnosis of Pili bifurcati is made by microscopic examination of the hair. The hair shafts show bifurcation, which can be seen at any point along the length of the hair. The bifurcation may be multiple and can affect any hair on the body.

Treatment

There is no specific treatment for Pili bifurcati. Management is supportive and includes gentle hair care to prevent breakage. In some cases, the use of conditioners and other hair care products may be helpful.
