Ingredients

1 cup olive oil
2 tbsp castor oil
1/2 cup finely minced fresh or dried rosemary (Salvia rosmarinus) leaf (no stems, flowers are fine too)

Instructions

Set up a double boiler and turn the heat to low. You want the oil to be warm, but never too hot to touch. Gentle heat helps extract the plant's qualities without damaging them.
Add the finely minced rosemary to the warm oil and stir occasionally for about 20 minutes. Chopping the herb finely is key here, it increases the surface area and allows for better extraction of the plant's volatile oils.
After 20 minutes, turn off the heat and let the oil sit at room temperature for another hour to continue infusing. Once it's ready, strain out the rosemary and pour the oil into a clean glass jar or a 2-oz dropper bottle for easy use.
Store your rosemary hair oil in a dark location.
Oil made with dried rosemary has a shelf life of one year.
Oil made with fresh rosemary has a shelf life of three months. I don't let it sit around, though. Treat oil made with fresh plants like a food and use it up.

Notes

To Use:

Warm a bit of the oil between your palms before applying- it feels amazing on the scalp. You can also use a simple cup warmer to warm your 2-oz bottle before applying the oil. I keep a cup warmer in my self-care area to warm my oils before using them. Simply put a teacup with water on the cup warmer and then put your bottle of oil in the water until it is warm.
Start with a couple of dropperfuls if you're oiling only your scalp. For more thorough treatments, if you have a dry scalp or a lot of hair, feel free to use up to ¼ cup. Massage it in slowly, making sure to get right down to the roots. You can leave it in for at least 30 minutes before rinsing it out, or wrap your hair in a towel or shower cap and leave it in overnight.
Use it 1–2 times a month, and give your hair the steady love it deserves.
