I remember when I was a child, my hair grew very fast and long, and I never cut it. When I was six or seven years old, my hair was waist high. I remember going to my mother's place in the summer vacation when I was six or seven years old. My mother found lice on my head, and the first decision she made was to cut off my long hair.
At that time, when I was young, my mother said that I would cut my hair as soon as I cut it, instead of paying attention to image as I do now. My sister and I both have them on our heads, but at that time, we didn't want our mother to cut our hair. After cutting my hair, my mother insisted on washing my hair every day, and so did my sister. Later, there were no lice on my head, and inexplicably, there were no lice on my sister's head.
I remember telling my mother with special regret that I should never have cut my hair if I had known that I could get rid of lice by washing my hair. But beyond that, it was too late, and the cut hair could not be reattached.
But from my story, we can find that children have lice on their heads, and mothers can insist on washing their hair, because lice are mostly health problems. Wash it for a long time and it will disappear naturally.
