“Hello, i have been using essential rosemary oil for 1 year and it has definitely given me the result. My hair fall is under control and i have new hair growth. I use 10 drops of rosemary into 2 spoons of carrier coconut oil for hair massage.”
U/READINGAFFAIR ↗“Rosemary oil is useless I used to use it but did absolutely nothing for my hair”
U/RANDOM_FELLOW9 ↗“It does work. It took me about 18 months to start seeing some results. It's better than Minoxidil as you don't have the facial hair growth in unwanted areas.”

Add context that might help others — skin type, conditions like PCOS, what you'd tried before. The more specific, the more useful.
