It contains over 190 biologically active compounds, including vitamin C (15 times more than an orange), vitamin A (three times more than a carrot), and vitamin E. It also has high concentrations of the rare omega-7, making up 40 percent of the berry. Typically only found in fish oil, omega-7 keeps free radicals at bay and promotes the production of collagen, a key building block for skin, hair, and nails.

Sea buckthorn has been thoroughly researched in over 130 modern scientific studies that have found that this berry promotes health. Women throughout the ages have used the obliphica berry to protect themselves against the ravages of the sun and the elements.

I love the smell...I LOVE this spray...It has a surprisingly nice hold even though it's more of a thickening hairspray than a firm hold hairspray -- I definitely recommend it for keeping your hair up, for providing your hair with body, and for getting a nice smell :) One negative: it's a bit tricky to apply since it's not an aerosol, but a spray, so you have to let it fall where it falls and let your hair dry a bit before letting go of your hold...However, the B&B hair spray works amazing, full hair, thick, and I notice it the most when I pull it back in a ponytail - normally my thin hair barely holds on in a ponytail holder, now it's thick and sturdy
