I have very long , fine wavy hair and I am in the ocean all the time . I just love the smell and how it makes ,y hair feel soft.I have to honestly say that this is heavier than Morccan Oil . I love Moroccan Oil and that is what I would use to go out shopping or to dinner. With the Macadamia Oil , one large pump is probably heavier than the average person who is not going surfing later, would want in their hair. That said, a dime or pea size would leave soft, beautifully delicious smelling hair. One large pump leaves my hair a bit greasy, which I like, and my hair is almost to my waist. The smell is simply Devine.I would also highly recommend their tub if conditioner . It is one of two products I've ever found that will make the driest , hardest snarls just melt away into silky, soft hair....and it smells delicious as well.I originally got the oil as a sample and have been buying it consistently ever since. If you have coarse or thick hair , you will love to use this anytime. If you have fine hair, a bottle should last you months!
