Although it’s not clear how rosemary works for hair loss, applying it to the scalp increases blood circulation. So how can you use rosemary to stimulate hair growth? Here are several options: 1. Daily Shampooing For nourishing your hair on a daily basis add rosemary essential oil to your shampoo or conditioner. Use 2 drops of oil for every ounce of shampoo or conditioner. Alternatively you can use the herb itself. Place approximately 1 qt. of distilled water in a large saucepan. Bring the water to a boil and stir 1-2 large handfuls of dried rosemary leaves into the boiling water (if you use fresh rosemary you need to double the amount of herb as dried herb is more concentrated). Turn off the heat and allow the rosemary to steep in the water for at least 5 hours. Pour the rosemary infusion into a dark-colored glass jar and store it in your refrigerator. Use the rosemary infusion to make basic rosemary shampoo by mixing 1/4 cup of the infusion with 1 cup of liquid Castile soap. 2. Daily Massage For a daily massage to stimulate new growth, add two drops of rosemary oil to one ounce of carrier oil such as jojoba oil. Rub into the scalp for three minutes before showering. 3. Hot Oil Treatment once or twice a week Once a week use a hot oil treatment for your hair and scalp. You will need three tablespoons of carrier such as jojoba oil and 5 drops of rosemary essential oil. Mix the carrier oil and rosemary essential oil in a small glass jar that can be sealed. Place the jar in a bowl of boiled water until the oil is warm. Gradually massage the entire amount using your fingertips into your dry scalp for several minutes. Make sure to apply a little blend down the length of your hair until the ends. Wrap your hair with plastic wrap or plastic shower cap, and then cover it with a very warm damp towel. Replace with another warm towel once the first one has cooled. Leave the blend for at least 30-45. You can stay with it overnight, and if you do this, remove the plastic wrap and sleep with a dry towel on your pillow to absorb the oil. Then rinse and lightly shampoo your hair with a chemical free shampoo. Follow with conditioners you want.
