Oh dear. This poor woman. She's simply humorously describing how bad her hair looked.
Have you ever had a bad haircut? Your hair looks awful. But you think "I won't worry - it'll grow back" and you continue.
Have you ever had a good haircut, but you wait too long to get it cut again, so it looks all wrong?
Now combine the worst aspects of each of these situations. That is how she thinks she looks.
