Handmade showercaps - made in Melbourne, Australia.
Fits most people, including those with lots of hair.
Shameful showercaps have a cotton outer, and are lined with water resistant fabric like that used in shower curtains, tents, and umbrellas. The cotton outer will get wet during your shower, but the lining will keep your hair dry.
After use, put your showercap somewhere where it will dry overnight for use the next day. Although not essential, showercaps can be washed in the washing machine. Choose a cycle with a cool to warm temperature, and wash with like colours. Do not bleach, dry clean, or iron.
Naturally, the colours may appear different on the screen than in real life.
