Everyone in my family- myself included- has a bad habit of leaving a bottle of body wash, shampoo, conditioner, etc, etc, etc. about a quarter full and moving on to the next bottle. This is entirely my fault because I constantly buy that stuff when I see it on sale, so we constantly have shampoo, body wash, and conditioner at the ready. We also have several gift packs of that sort of junk.
Finally, I got tired of my bathroom being piled up with all that stuff, so I got a giant bottle of shampoo that someone had bought at Sam’s (about 1/4th full, natch) and filled it up with all the dribs and drabs of body wash, shampoo, and conditioner, then put in several of the little bottles from gift packs in there. I figured it would smell like a hot mess, but surprisingly, it didn’t smell too bad.
I then handed the bottle to my oldest son who takes about 73 showers a day and told him to use it as body wash, and once this bottle was completely empty, I would buy him any kind of body wash he wanted. He liked the smell and liked how it made his skin feel smooth. (Probably due to the conditioner in there, my guess.)
It’s an easy way to use up the little bits you end up with!
