For everyday use, apply a few drops of the oil to the scalp, comb it through to the ends, and style as usual.

How do I use rosemary oil for hair growth?

You’ll find all kinds of rosemary remedies online, from homegrown herb/oil infusions to spiking haircare with essential oil drops. But the best way to incorporate it into your routine? Apply diluted rosemary oil directly to the roots or bald patches and massage it into the scalp. Massage increases the oxygenation of hair follicles through increased blood flow, and according to Claire Martin (brand educator at bestselling brand Mielle Organics) a large supply of oxygen is crucial for hair to grow at its full potential.
