I was talking with a friend earlier this week about hair. Her daughter and she are both blessed with beautiful, very thick hair. She was talking about how years ago one of her daughter’s classmates had lice. She looked at her daughter’s very thick hair and realized that if she were to ever get lice it would be even more difficult to remove the nits from such a full head of hair. Luckily, she never had to test her theory. Since that time, she’s been adding a bit of tea tree oil to all of the family’s shampoo to help prevent lice outbreaks. I found this article which tells a bit more about tea tree oil as a prevention method.
