Question

Is this sentence correct?

"He had stiff reddish-golden hair that stood up like a horses mane."

Answer 1

"He had stiff reddish-golden hair that stood up like a horses mane." needs that adjective "stiff" to be an adverb for that adjective "reddish-golden": "stiffly". The noun "horses" is missing an apostrophe: "horse's" for that noun "mane". The noun "that" needs to be "which", used to add information to objects, items, people, situations, etc.

The correct sentence would be: "He had stiffly reddish-golden hair which stood up like a horse's mane."

Answer 2

Almost.

He had stiff, reddish-golden hair that stood up like a horse's mane.

Answer 3

Minor punctuation issues but overall "correct" (horse's mane).  It does convey a vivid image.

Answer 4

No, your sentence is not quite correct. It should have a comma after 'stiff', and an apostrophe on horses, like this: horse's. Apart from those two errors, your sentence is correct and easily understood.
