Loofahs
Loofahs are brilliant. They exfoliate your skin and give you just the right amount of lather with your soap. They can make your shower experience a million times better. However, they don’t last forever, and if you’ve ever had one for over six months, you probably already know.
Every time you use your loofah to exfoliate dead skin from your limbs it gets full of, well, dead skin. These cells don’t go away when you wash the loofah, so not replacing it can mean you end up with a nasty bacterial infection, especially if you rub the loofah over an open wound.
