"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."

"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 love this spray. It gives my hair soft volume, not va va voom 1980s volume, but it's just a pretty soft look and it has really been helping the condition of my hair. My hair is softer when I use [...] it. It's amazing, it really helps. 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, then I popped in the rollers and I had just a nice soft volume to my hair."

"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.

[...] 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."

"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."

"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."
