I think the first thing to consider is a person's habits. There is no absolute morning, or night, sometimes too busy at night, or too tired, just want to fall asleep on the head and have no time to wash or blow dry hair, this is a very time-consuming thing, especially for girls.

On the contrary, getting up in the morning and washing your hair, then eating a breakfast and going to work in good spirits is a very good choice. I as a boy. Every day after sleeping my hair is messy. Got up in the morning and washed my hair. Instantly feel refreshed. Feel especially refreshed. I myself am partial to getting up in the morning to wash my hair.
