What They Say: "A weightless, anti-frizz serum that smooths and adds brilliant shine to the hair. The best silicone-based product that appeals to both fine and thick coarse hair. Provides a silky soft, glossy finish for more youthful-looking hair."

Jen's Experience: I love making my hair look shiny, and I love Alterna products, so this seemed like a match made in heaven. I've used a lot of shine serums in the past, so luckily I was aware that a little of this sort of thing goes a long way. For this product especially, a single pump is plenty for my fine hair; any more and I look like I need to get back in the shower. Because it really makes my hair slick with the smallest amount, I've been a little wary of using it close to the scalp, but it's a great way to bring out my layers and keep frizziness to a minimum. I really love the way it makes my hair smell, clean and not perfume-y at all. Overall, this isn't my favorite shine serum, but now that I have mostly gotten a handle on how to apply it without looking too greasy, it does what it claims.
