Does tea tree oil cause hair loss?

There is no scientific evidence to suggest that tea tree oil causes hair loss. In fact, tea tree oil is often used as a natural remedy to promote hair growth and reduce dandruff. Tea tree oil has antifungal and antibacterial properties, which may help to keep the scalp healthy and free of infection, which can contribute to hair loss. However, it's important to note that some individuals may experience an allergic reaction to tea tree oil, so it's always a good idea to do a patch test before applying it to your scalp.
