So upset with how my hair has held up for my wedding tonight. It was done at 2 and by 5 it's gone entirely flat and the braid has fallen down. No answer tonight to get it fixed by 6pm for a 10pm ceremony. What a nightmare. If it had held up I would have loved it. But this is really unacceptable. $100 curls and a braid should hold up.
