Im trying to stimulate my hair growth rate and heard that rosemary oil is an excellent way of doing this. however, i am unsure if applying it straight from the bottle to my scalp is the best way to go, or if i should combine it with a carrier oil such as jojoba which i hear has excellent moisturizing elements. my hair is dry and thick and I would like to know if this mixture of the two oils will help at all. Also, i am absloutely stumped as to how much rosemary oil to use per teaspoon of jojoba or if should use any at all. If anyone lives in the Dallas area and knows a reputable manufacturer where i can purchase High-Quality, pure oils, I'd really appreciate the feedback.
