Hate some parts of canal - they're quite hairy (10)
I believe the answer is:
dreadlocks
I'm afraid I can't explain this answer.
Can you help me to learn more?
(Other definitions for dreadlocks that I've seen before include "They're pretty hairy!" , "Jamaican hairstyle" , "great shock" , "Long, tight hair braids" , "Barnet" .)
