This is a package of 15 shower caps for $1. I use a shower cap over my hair when I apply my henna hair dye. These will come in very handy. They are also good for when you do a deep oil conditioning. The plastic holds in the heat from your head, making it a "hot oil" treatment. I think I better pick up another pack of these, as well.
I also bought these covers for using on your leftovers (or for keeping the fruit flies out of your fermenting sourdough). A pack of 20 covers, in 3 different sizes, for $1. The plastic is rather thin but I am hoping to be able to wash and reuse them.
I found these items at the Dollar Tree on Pacific Avenue, between 96th and 112th.
