The Science Behind It
A 2015 study published in SKINmed Journal demonstrated that rosemary oil is as effective as 2% minoxidil for treating androgenetic alopecia after 6 months of use. Participants using rosemary oil experienced significant hair growth with fewer side effects compared to minoxidil, including reduced scalp itching.
Rosemary oil showed comparable efficacy to minoxidil 2% in promoting hair regrowth, with a significantly better tolerability profile.
