Got plenty of Malay barbers around. U just gotta look. But generally speaking they cater to higher-end market. I just avail of rm10 bangla or rm15 Indian when in KL.

In Sabah my usual Malay-Filipino barber does a great job. Been going to him for many years since he was a bachelor and haircuts were rm6.50. His eldest kid is in std 2 now and haircuts cost me rm12. How time flies.
