Having 7 long-haired daughters means we deal with lots of tangles, so I like to save money by making my own detangling spray.
I use generic spray bottles and fill about 3/4 full of water. Then I fill up the rest with conditioner and give it a good shake.
Since dealing with our lice epidemic, I add a few drops of tea tree oil, which is supposed to repel lice.
Whenever I do hair, I always have this homemade detangling spray handy and it makes styling a breeze.
