Then, hold the swim cap wide open with your bent palms.Starting at your forehead, pull the cap over your hair and down towards the nape of your neck. Finally, any stray hairs can be tucked under the cap to make sure the cap will not slip away.Try using baby power, talcum power, or corn starch in the cap while in storage, making it easier to put on without snaggingThe Benefits of Swim Caps:Swimming caps are designed for competitive swimmers in order to reduce hydrodynamic drag while swimming. By creating a smooth surface area for the water to flow over, caps allow swimmers to move more quickly and fluidly through the water than they could without a cap. This, in turn, improves mobility while swimming – helping you to perform better in competition.In addition to their performance benefits, there are many other reasons to wear a cap. Some people use swim caps to help keep water out of their hair, which helps to reduce the damage that chlorine and other pool chemicals may cause. Unlike shower caps, however, swim caps are meant to reduce drag – not keep the hair dry. There is no swimming cap specifically made for this purpose.Shower caps work because the head is rarely fully immersed in water. Rather, the cap blocks splashes and droplets of water. When swimming in the pool where the head is below the water line, a water-tight seal would be required to keep hair completely dry.Thus, there's no guarantee your hair will stay completely dry.
