Rosemary water and rosemary oil are both believed to have benefits for hair growth and scalp health, but they may have different levels of effectiveness.
Rosemary oil is a concentrated essential oil that is extracted from the rosemary plant. It contains high levels of active compounds like rosmarinic acid and caffeic acid, which have been shown to have antioxidant and anti-inflammatory properties that can help to promote hair growth and improve scalp health.
On the other hand, rosemary water is made by steeping fresh or dried rosemary leaves in water, which extracts some of the plant's beneficial compounds but at a much lower concentration than the oil. Rosemary water may still have some benefits for hair growth and scalp health, but it may not be as potent or effective as the oil.
That being said, both rosemary oil and rosemary water can be used as a natural hair care remedy, and they may provide some benefits for promoting hair growth and improving scalp health. However, it's important to note that individual results may vary, and more research is needed to fully understand the benefits of rosemary for hair growth and health.
