Splash Happy Shower Caps are highly water resistant, which means you can splash and dip your head under the shower head, and your hair will stay dry.   When used in the shower, it is recommended that you angle the shower head down to the base of your neck.  Your Splash Happy Shower Cap will protect your hair from splashes and humidity.  If you run a tap over the Cap, you will notice that the water beads straight off.  But we wouldn’t recommend standing with the Shower Cap under the shower head for an extended amount of time.  It’s likely that nothing will come through, however, it’s important to note these are not completely waterproof.  Waterproof fabrics tend to be very stiff and look a bit more like shower curtain material.  The fabric used for our Shower Caps is very soft and really lovely to wear.
