Would it be "Ella estuvo" here if we add a specific time like "Ella estuvo lavándose el pelo de 8 a la 8:30" ?
Also, we would appreciate the El indefinido progresivo examples with all pronouns as just having 3 is not enough to remember the conjugations.

Yes, if you add some sort of delimitation, it's natural to use the preterite progressive as it conveys an ongoing action in the past that had a specific duration and ended at a certain point.
With regards with extra examples, I added the links to the lessons that explain how to form these two tenses so you can find example sentences there with all pronouns.
I hope it helps.
Saludos cordiales
