This is an amazing product! I am 53 years old, so I've had the opportunity to try many hair products over the years. I have fine, limp, straight hair that is also prone to frizz so in general looks unhealthy. I have never been able to tolerate any kind of "cones" in hair products. They might work well once but then my hair ends up looking worse. Given that, I would never have even tried this if there had not been an incorrect ingredient list for it on the Sephora website. I think they may have listed the related primer's ingredients instead. So I sampled it, believing it was cone-free, which it is not. Miraculously, I am getting spectacular results with this product. I even waited to review it in case it was just a flash in the pan. After about 4 uses, I'm officially in love. I wash & condition with Living Proof Timeless then work less than a dime size amount of this through towel dried hair, avoiding the roots for the most part. When I'm ready to blow dry, I work a pea size blob of Living Proof 5-in-1 through my hair and go at it with a big round brush. My drying time is reduced and for the first time in my life, I actually like my own blowout better than the one I get from my hairdresser. My hair is shiny, has lots of body and bounce with zero frizz and lasts for days. While the other stuff I'm using is good, it's not new in my routine, so I know this product is the one that is giving me such fabulous results. If you have fine, frizzy hair, YOU MUST TRY THIS!!!!
