    What the gurus are saying

    This spray delivers gentle, lasting root lift without the drying damage that often comes with volumizers. The gurus who tested it found their hair stayed soft and conditioned even with regular use, and the volume held through a second day without brittleness or frizz. It won't give dramatic 1980s-style fullness, but creates a softer, more natural wave that conditions as it lifts.

    "I use it with those Velcro rollers that I've shared with you before, and I really like it. It gives me nice volume. It gives my hair a little shine. It also the rollers come out nice and smoothly. If you have tried the K18, this is their Astro Lift Volumizing Spray. It definitely helps my really dry, brittle ends and also gives me a touch of volume. So I'm a fan on this and I already have my backup."

    "I put this when I'm styling my hair, like when I'm putting it up in my rollers. I'll kind of give my hair a spritz and my hair just comes out really shiny and soft and with volume. You wouldn't think that because my hair is so fine and lightweight that it might weigh it down. This does not at all."

    "Another hair win has been the K18 Astro Lift. Love this. You can use it on wet hair. You can use it on dry hair. When I towel dry my hair, I just spritz a little bit of this in and then just let it air dry. And on the days when I do my rollers, which is usually on dry hair, I just spritz this in at the roots, put in my rollers, let it air dry, and this gives me so much volume. It doesn't say much about bonder repair, but my hair is so silky and shiny after using this. In addition to a bit of volume, I get that silk and that shine and that just really soft touch. This has been a huge hair favorite in the last couple months."

    "I dampened my hair with a little bit of the K18 Astro Lift Volumizing Spray, threw in the rollers, let this air dry for a little while, and when I took it down my hair was so soft and so conditioned. This doesn't give va va voom volume, but it gives nice soft waves and truly conditions the hair. It gives my hair soft volume, not va va voom 1980s volume, but it's just a pretty soft look. It has really been helping the condition of my hair. My hair is softer when I use it. I like it more than the original K18 Bond Repair, and I actually think I like it more than the Living Proof Bond Repair that I've been using for the past couple years. It's just easy. I popped in the rollers and I had just a nice soft volume to my hair. This stuff is amazing."

    "This is K18. This is their new Astro Lift and it's supposed to be for repairative volume spray. It is kind of like a bond repair that you can use when you're styling your hair. You can put it on wet hair, you can put it on dry hair. I got about at least a little over a third left. I've had this since launch and that's been a good six or eight months. What I do is I spray it on and put in my rollers and I love it and it just my hair is so soft and silky after using it."

    "The K18 Astro Lift Volumizing Spray [...] is kind of taking it to the next level for me. I feel like I'm getting some nice little lift, nice little bit of volume at my root and it's because of this spray. What I really like about it is it's long lasting. I can spray it on my roots, dry my hair, and even my second day hair has some really nice lift to it, but it doesn't damage my hair. I feel like a lot of volumizing sprays really dry out your hair in a way that makes it so with long-term use it makes your hair more brittle, more dry, and it looks more frizzy. It looks damaged. I've been using this almost all of this year, [...] almost every hair wash and dry, [...] most of them, and I have not sustained any of that drying, brittle damage that other volumizing sprays do because they're using that K18 technology to keep your hair nice and healthy. I just really like what it does for my hair."

    "This is really great for getting lift at the root, which is hard for me to achieve because my hair is very thick and it's long and that means it's very weighed down. I've tried volume sprays in the past that just haven't really been very impressive. Then I tried this and this was very impressive. I will put this right at the root, lift up my hair around my crown and in the back and then blow dry my hair. It offers a lot of nice lift at the root. I find that the best effect with this is damp hair and then blow drying it. You're going to get the most lift, but you could use this on dry hair, too, if you wanted just to kind of get a little perk up at the roots. I think it works best on damp hair with a blow dryer. It smells really good, too. There's almost like a creamy vanilla hit to the scent of this that is really appealing to me. I really really enjoy how this smells. I do find that volume sprays sometimes dry out your hair or make your scalp kind of itchy. And this actually doesn't do that to your scalp or to your hair at all."

    "I also used right at the roots the K18 Astro Lift spray. This is a volumizing spray that I really enjoy and it really does bring some nice body into my hair. And I slept on this hair, washed it last night, dried it and slept on it and there's still some nice volume at the roots. So I like how this lasts."
