Orbiting with curls: Jessica Meir reveals zero-G hair routine from the ISS

NASA astronaut Jessica Meir shares her zero-G curly-hair routine aboard the ISS: she uses no-rinse shampoo focusing on the scalp, rinses with a water pouch, dries with a dedicated T-shirt, avoids brushes to reduce frizz, and applies leave-in conditioner; humidity isn’t a major issue in microgravity, and she notes Earthly 3a curls become more like 3c in space, with a real shower back on Earth anticipated.
