While I've become more grateful for my body and the experiences it has afforded me, one of my more superficial self-image distractions is my hair. I've long loved the color, but I've just never felt like I have that shampoo-commercial-worthy mane. Where I wish it were full and bouncy, it's fine and flat; where I dream about layers with lift, the reality of my mane is much less defined. Of course, you'd probably never think that based on seeing photos of my hair when it's done. The reason? After being in the beauty industry for the past decade, I know a thing or two about high-quality hair care. And when it comes to brands that I can always count on, R+Co is at the top of the list.

While I've tried many R+Co products over the years, most recently, the Dallas Biotin Thickening Treatment earned its permanent spot on my shower shelf. And now, its post-shower styling sister, the R+Co Dallas Thickening Spray ($32), has received the same star treatment.

In the bottle, the R+Co Dallas Thickening Spray honestly looks like water. It's a true liquid, not a serum or oil that spritzes on. It's formulated with hydrating and smoothing aloe leaf extract, protecting and conditioning ginger root extract, volumizing pro-vitamin B5, and an amino acid complex that protects against heat damage while boosting the hair's overall structure. While it's infused with fragrance, it's not heavy or overpowering—it simply smells warm and delicious like the rest of the Dallas line.

To put this spray to the test, I spritzed it onto towel-dried hair. Usually, when I apply styling products, I try to spritz them in while my hair is still quite damp, but by the time I got around to sitting down with my Dyson Airwrap ($599), my hair was probably 85 percent dry already. Because of this, I was slightly worried that spritzing on the Thickening Spray would leave a weird, product-y residue that even my Round Volumizing Brush attachment couldn't salvage. But that was so far from the case. Instead, after spritzing my hair from roots to ends and between layers of hair—focusing primarily around my roots—I found that the styling process couldn't have gone more smoothly, literally and figuratively.

Normally,  I ward off frizz by spritzing my hair with the Color Wow Dream Coat Supernatural Spray Anti-Frizz Treatment ($28), a tried-and-true I've sworn by for years. But to objectively analyze the R+Co Dallas Thickening Spray's performance, I let it be the only styler in my strands. And the results speak for themselves.

While this spray doesn't give me va-va-voom volume reminiscent of retro rollers (I wish it were that easy!), it absolutely made my hair feel thicker and look smoother. Best of all, it gave each strand a bit of grip, which my hair normally lacks. Because of this, I found that my face-framing layers didn't separate from the rest of my hair, which they normally do.

I'm not the only one who's a fan of the formula—it's earned nearly 2,000 five-star reviews on Amazon. "I have very fine thin hair and it really leaves my hair fuller and manageable," writes one user. "I have purchased so many hair products that never work like they say. This one is awesome and worth the money. Highly recommend," says another.

Needless to say, I will be keeping a bottle of this chicly-packaged thickening spray on my vanity from now on, and at last, I'll be able to feel confident wearing my hair fully down.

But wait, there's more!
