Add olive oil to the glass dropper bottle. Add the essential oils and nettle extract. Then fill the bottle the rest of the way with jojoba oil. Screw the lid on and shake well to combine.
To use, place several drops of oil on fingertips and rub your hands together to evenly distribute them. Run fingers through your hair at the scalp, starting at the front hairline and finishing at the base of the neck. Apply more oil as needed.
Store oil in the refrigerator to ensure the extracts stay fresh. Will keep indefinitely.
There are a lot of different ingredients purported to improve hair and scalp health. Feel free to mix and match carrier and essential oils as well as any extracts you see fit. I promise, you can't mess it up.
