Given life to my fine hair
This spray has become a staple in my hair care routine, and I genuinely notice the difference every time I use it. The K18 AstroLift Reparative Volume Spray gives my hair a light, lifted look that lasts throughout the day without feeling stiff or sticky. I have fine hair that tends to fall flat quickly, but this product adds volume in a way that still feels natural when I run my fingers through it. The scent is pleasant and subtle, and it blends well with other products I use without clashing. What really stood out was how this spray improved the overall texture and resilience of my hair. After a few weeks of consistent use, my hair feels stronger and less prone to breakage. I used to notice frizz and lifeless strands by mid-afternoon, but the lift and body this spray provides stays intact for two days as advertised, even through workouts and humid conditions. I appreciate that it supports healthier hair over time rather than just giving temporary fullness. It has genuinely elevated my styling routine and made daily hair care feel easier and more effective.

One of the best hair products I’ve ever used!
I’m obsessed with this hair product. It not only adds tons of volume with weighing your hair done but it adds softness and decreases frizz. My hair is five and it’s literally one of the best products if ever used. I use it everyday and there is zero buildup. It’s worth every penny.

Perfect product.
This stuff is amazing! I’ve tried so many products that claim to give body and lift to my really fine hair by K18 is the only one that actually delivers the kind of body I was looking for. Clean, shiny and smooth. I love it. Ordered the travel and large size. It’s great for wet hair or for dry.

I've been using it for over a year, you should use it too.
I have been using this product for just over a year. It's fabulous. All of k18 products are more than meets the eye. It repairs your hair at a molecular level while leaving it thicker and so soft. So easy to use, just a few sprays and the fragrance is intoxicating...everyone comments. So this summer treat yourself to K18 AstroLift a feel the difference, it's like a moisturizer for your hair, no stickiness or dryness...just soft and luxurious. Your hair will thank you.

Omg I love this & it smells amazing
This is a great product for me. I have long, fine , straight hair that I always air dry. I love that I can use it on damp or dry hair and it’s a volumizing spray you don’t have to blow dry. Makes my hair look thicker and more voluminous. Also, the scent is amazing, I would literally buy it in a perfume lol. Got the small size first to try, definitely getting the full size when it’s out.

Creates the promised volume
A tad expensive but actually delivers the promised volume. Definitely will replace the other products that I have been using. Works great on fine hair without adding weight.

It’s ok, smells great.
Smells great! Don’t think it gives super high volume compared to R&Co Dallas spray or Kerastase thermatique volume mousse. So might not be repurchasing. But love how you can use on dry hair as well.

Love it!
Wow, I am so glad I found this. I have thick but somewhat fine hair and live in a humid climate in Florida so I have my fair share of bad hair days. I spray this on my damp hair on the roots and run my fingers through my hair and blow dry. It gives me great lift and makes your hair so soft and also lasts all day with a little hairspray. No stickiness or crunchy build up whatsoever! I love this stuff just wish it was a little less expensive. I don’t use a lot so the small bottle lasts a long time.

Zero Volume
This did nothing for my fine thin hair. 2 stars because it smelled nice. Definitely not worth $23 for 1.6 fl oz.! It was as good as putting nothing in my hair. I'm really disappointed because all the reviews made it seem like this was the miracle product to get that full hair look.

Makes your hair so thick looking
I love this stuff . I have very thin thin hair and I use this on wet hair and blow-dry and it looks like I have a lot of hair. It's amazing. Best thickener I ever used.

K18 Astro-Lift Spray
This has proven to be one of my most favorite products. I use this daily after my daily routine, spray on wet hair, work it through then blow dry. My hair texture has changed and is more manageable. The smell of the product is just enough to smell good but isn’t overpowering at all. Every third day I add K18 leave in conditioner to this step for added protection. My hair has never been healthier.

Not too bad with fine hair
I tried the travel size after seeing it used by content creator @diyhairschool. I have very, very fine hair that is also pretty heavy and thinning a bit. I like this because it doesn't make my hair look dirty or greasy (which can happen so easily) but I don't always feel like it does much. Sometimes I think it's amazing, sometimes I'm not sure it did anything. I will say that it doesn't mess up my current routine so I'm going to continue to use it for now, I'm not sure I will end up buying a full sized product though.

Fine or thinning hair ? Look elsewhere
If you have fine hair- NOT for you Was so disappointed in this . I have aging and thinning hair and this is marketed as a fullness boost . It did the exact opposite . While I appreciate the fact it made my hair super soft, that was not the goal . Back to the drawing board ..
