The easiest way to improve hair health? Sleep in a kaxi sleep scrunchie! This scrunchie has significantly more material than a normal sized scrunchie. They are specifically designed to sleep in because of the soft silk material it is made of. Silk helps hair retain natural hair oils, and also helps minimizing tangling and breakage while tossing and turning at night. Sleep with it in a LOOSE low pony, side braid, or high pony/bun above your head as you sleep.
