Conversation:
I am a men and I struggle with my family because I want to have long hair and they dont let me, I have pretty brown hair!
I'm sorry to hear that. In some societies short hair in men is seen as being under society's control in some way, like in the military or in jail.
Actually yes I like to feel free! im straight one of my concersn also is if girls will like me with long hair
I wouldn't know if they'd find you more attractive, but long hair in females is seen as attractive by both women and men.
I'm a little bit insecure! But I think brown hair is still manly! Blonde hair is more for girls.
I see. Do you still want long hair?
Of course! Do you know how long it will take to grow 10 cm hair?

Response: Ah, for most adults, it takes 5 months to produce 10 cm of hair.
