sported ... hair down past his shoulders.

[GoodTaste]

If "sport" mean "wear" here, then "sported hair" sounds as if the hair is not natural growing but is artificial. I am not sure.

Is the hair artificial or natural? If the latter is the case, you need not to wear. It is there for you. I am not sure how to understand it.

Good question.

His hair is real. He sported long hair. Sport means wear, but it's more flamboyant. He's not just wearing it, he's showing it off. He's parading it. He's flaunting it.

Is the hair artificial or natural?

Natural.

If the latter is the case, you need not to wear.

As a matter of fact, we do wear our hair. (It's idiomatic.) Some wear it long. Some wear it short. Some wear it dyed, braided, permed, or corn-rowed. If you have a mullet, you wear it long in back and short in front.

How do you wear your hair?

It is there for you. I am not sure how to understand it.

You need not[STRIKE] to [/STRIKE]wear. It is there for you. I am not sure [STRIKE]how to understand it[/STRIKE] what it means.

"Need not" is followed by the verb, without "to".
I don't think "how to understand something" is correct.

 

[GoodTaste]

"Need not" is followed by the verb, without "to".

No. "Need not wear" is wrong because it means "should not wear" - "should not wear hair"? - how odd it sounds!

"Do not need to wear" mean "Do not have to wear"- That is the meaning of "need not to wear". The phrase "need not to do" sounds classical and a bit old-fashioned, though.

I don't think "how to understand something" is correct.

OK. Let see what native speakers will answer.

What about the second part, Piscean?

 

[GoodTaste]

It doesn't.

'Need not to wear' is incorrect.

If so, how about "do not need to wear"?

Besides, you haven't offered the definitions for each "need" there, which will explain why clearly rather than make them suspensive.
