"그녀는 머리카락이 검어요." and "She has black hair." would be a better sentence set.
Anyone know what 카락 translates? I've only ever seen 머리 alone used for head and hair
카락 etymologically originated from '가락', which means a thin and long material like threads. '머리' means 'head', but it can mean 'hair', too. '머리카락' means 'hair' only.
The pattern is intuitive if you think about slender extensions of your body all as a kind of 가락:
Thank you so much your comment really helped:)
A similar word/part is used in the words for finger (손카락) and toe (발가락). I was always under the impression that 가락 and 카락 refer to extremities.
