Why did shmuel shave his head?

Shmuel shaved his head as part of a traditional Jewish mourning practice known as "Kriah," which involves tearing or cutting hair to symbolize grief and loss. This act reflects his deep sorrow over the tragic events he experienced, particularly the loss of family and community during the Holocaust. Shaving his head also serves as a visible sign of his mourning, emphasizing the profound impact of his experiences.
