Combine all the ingredients in a dark glass bottle. A brown dropper bottle can be used, but I reuse the black cumin seed bottle because it is special miron glass that protects the oils from going rancid for years.
Moisten hair and massage 10-30 drops (or ½ to 1 teaspoon) into the scalp.
Leave on for one hour or overnight and wash out. I recommend using at night and sleeping with a towel on the pillow to avoid oil stains.
Use once a week or as needed to increase hair growth.
Test the oils on a small part of the inner arm before using on the entire scalp and do not use if it causes any reaction or sensitivity. Black cumin seed oil will irritate the skin for a small percentage of people with sensitive skin.
