Rosemary (Rosmarinus officinalis) has a long history in traditional herbal hair care, usually as an infused oil massaged into the scalp rather than taken internally.
In most routines, rosemary oil isn't used alone — it's blended with carrier oils like jojoba or castor oil so it can be massaged in comfortably without irritating the scalp.
The ritual matters as much as the ingredient: a few minutes of gentle, circular massage helps distribute the oil evenly and gives you a moment to slow down, which is part of why so many people describe hair oiling as relaxing rather than purely functional.
As with any botanical, it's worth doing a small patch test first if you have sensitive skin, and discontinuing use if you notice any irritation.
