The overall result of the study provided evidence that rosemary oil may be effective for certain hair growth. A study from 2022 also found evidence that rosemary oil can aid in hair growth.
I use Rosemary essential oil (just a few drops) along with coconut oil and massage into my scalp.

You may start to see hair growth results within a few weeks of using a hair oil. However, it can take up to several months to see the full effects of using hair oil.
