Ingredients :
Castor Oil: Use 10 ml of pure, cold-pressed castor oil as the base. Rosemary Essential Oil: Based on the original recipe (4–6 drops for 30 ml), you can use about 2 drops for a 10 ml tube. This keeps the concentration around 1–2% of the total volume. Vitamin E Oil (Optional): For antioxidant benefits and to help extend shelf life, add about 1 drop of vitamin E oil.
