Many people wonder about the practicality and safety of leaving tea tree oil in their hair overnight. Here is a detailed study.

Potential benefits of overnight use

The benefits of leaving tea tree oil in your hair overnight can be substantial. It may help address issues like dandruff, irritation, and scalp acne while deeply moisturizing your hair.
