What is a good way to help encourage my roommate to cut her hair?

[CupcakeTheDestroyer]

My roommate has hair that goes down to her waist and she’s struggling with maintaining it. She’ll go a few days without brushing or combing it, which just create tangles on her tender head that make her reluctant to pick up a brush at all. Not to mention she’s depressed and so tired most days she doesn’t think to bother. I don’t want to try and shame her or make her feel guilty for growing out her hair, but at this stage of her life I feel like cutting most of it off would make her bad days a lot easier to handle. Any ideas?

Maybe you can try including her in some fun activity, for example you could invite a hairdresser friend at home, or who is learning to do that before starting it as a job and you're going to have your hair done for free, so she could get that too if she wants, and you add how her hair allows many special haircuts at the current state.
So that you don't have to imply anything bad and it's on her initiative to accept or not, feeling pushed because of the initiative and not because of feeling judged.
If she says no, well... You can retry a second time, but then not more.
