You might see certain muslim men from asian countries wearing a turban but this has nothing to do with Islam and more so influenced by personal taste, local customs, or cultural traditions of their countries. The Turban is not a universal symbol of Islam, is not a requirement & neither has it been prescribed.
The turban is worn & prescribed to the followers of the religion Sikhism, know as sikh's.
hope we've bettered your understanding of Islam.
Peace!
