Bought this for hair regrowth as recommended by a functional doctorThis was recommended by my doctor to help regrow hair. There are actual scientific studies that show that rosemary extract performed as well as minoxidil for hair regrowth, perhaps even better in some cases. Mix it with a carrier oil of your choice. I like jojoba oil with added aloe vera juice. It's 15 drops of essential oil per 6 teaspoons of carrier oil. Mix it together and massage it onto your scalp. Leave it on for about an hour before your shower. I would recommend doing a spot test first though, in case you find you're allergic to rosemary oil or anything else you'd be applying. I wish everyone great results!
