If you don’t know dreadlocks it is when your hair is like twisted but permenately. I don’t believe it interferes with your wudu as long as you take care of it. Thank you. Please support answer with Qur’an & or Sunnah.
Answer
In principle, it is not permissible for a male to style his hair according to the customs of the Kuffaar.
Therefore, to make dreadlocks for a male will not be permissible.
