I think she believes it makes her relatable, like Gi fletcher, when in reality they have more help around so less excuse to go round with greasy hair. Even people with a baby on their own manage to wash their hair at least once a week. Shower takes 2 mins. It's just laziness and not relatable at all. Rex would be absolutely fine on a playmat or in a bouncer for 5 mins while she washed her hair. Other people have to do it!
