Went to the salon today and found that they don't carry this particular product- ugh! The owner did say she would order it for me, but it would be 3-4 weeks. So, because I hate to pay shipping costs, I'm waiting. The herbal scent you noticed is probably rosemary. Apparently their whole line is designed to repel head lice.
