I have slightly coarse, slightly wavy hair that needs an oil or silicone based product applied before blow-drying it straight. (Otherwise, my hair has lots of fly-aways and tends to look slightly frizzy). I bought this product hoping it would give my hair a nice gloss, but instead, it left it rather limp. I tried using it several times, using a slightly different amount each time, but did not see a real difference. If you are looking for a product that is nourishing AND adds bounce, I would recommend the Agave Healing Oil Treatment (also sold on the Birchbox site!). I'd like to wrap it up by saying this product *may* work better on a different type of hair - I've seen reviews online with pics of people with stunning results - but for me, I found the Agave product more effective.
