NASA astronaut Jessica Meir has shared a demonstration on how she manages her curly hair while aboard the International Space Station (ISS), offering a rare glimpse into daily life in microgravity. Speaking from roughly 260 miles above Earth, Meir, 49, posted a video showing her hair care routine designed specifically for the unique environment of space.

In the clip, Meir applies drops of water and a no-rinse shampoo to her curly hair, which appears to have transformed from her typical 3a curl pattern on Earth to a tighter 3c texture in microgravity. She then dries her hair using a T-shirt and finishes with a modest amount of conditioner. “Curly-haired crew, this one’s for you,” Meir says, highlighting some of the unexpected benefits of her space hair, such as not needing to tie it back during exercise. However, Meir added she is looking forward to taking a shower on Earth upon her return.

The no-rinse shampoo used by Meir was developed by NASA to address the challenges posed by the space station’s limited water supplies and the absence of gravity. Unlike conventional shampoos, it is formulated to require no rinsing with water, thereby minimizing the use of this scarce resource and preventing floating droplets that could interfere with delicate instruments.

The astronaut’s video sparked interest and positive reactions on social media, with users expressing appreciation for the insight into a facet of space travel rarely discussed. One commenter noted the inspiration it could provide for future generations of curly-haired girls aspiring to become astronauts, while others admitted they had never considered how hair care might differ in space.

Meir’s demonstration underscores the ingenuity involved in adapting everyday routines for life in orbit and reflects NASA’s ongoing efforts to ensure astronaut comfort and hygiene during extended missions aboard the ISS.
