雷鬼头（Dreadlocks），也被称为锁子头（locks）

We usually call dreadlocks "雷鬼头"，but it sounds punky and we don't use it for self-introduction. “锁子头” (locks) might be more neutral, but it's not as well-known as "雷鬼头". "辫子头" is just okay if you are not trying to make a distinction, but "辫子" is usually considered as single (or double) braid or ponytail.
