Some earlier reviews said it smells very strong, and it does. Rosemary smells a lot. It's not something you want to use before going out among people. Just for the scalp, I got the tip to mix it with coconut oil, which worked very well for my sensitive scalp. I find that this oil helps my hair grow and makes it stronger/thicker, while coconut oil helps not to make it as strong and moisturizes the scalp. I try to use this combination 2 times/week (about 1 hour before washing or more), and it has saved my dry/sensitive scalp in the winter. Also, I really notice that my hair grows faster (when I massage it in for at least 1 minute each time). I believe in natural products over chemical shampoos, and this is as natural as it can get! A tip is to put coconut oil in the lengths, especially if you have damaged hair like me. The hair DRINKS the oil and feels great afterwards.
