20+ inches of straight black virgin hair

I’m a 23 y/o Asian woman.
My hair is a very dark brown that appears black in low light.

I wash my hair about three times a month with shampoo and conditioner then air dry after. I do not smoke, drink, or use any substances. I have never dyed, bleached, or used an iron to style my hair.

I had a blunt bob before growing out my hair, so it has no layers and is all one length. I am planning to cut to a chin-length blunt bob (again) after this but will consider shorter for the right price.
