Yeah it was exactly that deep despair I felt that made me want to donate it once it started growing back in -- my hair is one of the few things I actually really like about myself, to lose it felt truly awful and I want to spare someone else feeling that way for long. I don't know if I'll keep growing it out and donating it forever, I might only donate the one time (long hair is, also, a giant pain in the ass); but it bothered me more than the nausea -- and the nausea was fucking insane, first and only times I have ever projectile vomited in my life: being on chemo.

On that note, if you don't already have a bucket handy at home: buy a bucket they can keep at the bedside, or something else with a wide opening that's easy to aim for. Maybe also get some of those vomit bags they use in the hospital with the plastic ring that holds them open, they disappear easily into a pocket and are a great help when you're gonna be sick while away from a convenient place to hurl.

And make sure once they do finish evacuating the entire contents of their stomach that they put something back in there after, even if it's just a little soup or something; it is somehow even less fun retching on an empty stomach and they'll need the energy.
