First type of hair clips that don't give me a headache!
I have long hair and a lot of it.  When I put it up, it has a lot of weight to it and often gives me a headache when I've had it up an hour or two.  I use two of these at a time and just swirl my hair into a bun, put one in from the top, one from the bottom and it stays put.  I don't get any pulling or extra weight from the pins and no headache!  Wish I had found these ages ago, I've been a long time sufferer of hair-up heartache!  :)
