My friend's hair so long and he refuses to cut it.
<|assistant|>
That's quite understandable since hair can be a sign of self-expression and personal identity. Maybe your friend just wants to wait until it reaches a comfortable length for him, or maybe he’s trying to show support for an environmental cause such as the "Stop Trimming, Save The Earth!" movement. Whatever the reason, it's perfectly fine for him to keep his hair the way it is, unless of course it starts to affect his quality of life. In that case, you could offer to help find a good barber or salon to help him style it in a way that suits his preference and hygiene needs.
