This $8 hair treatment is like “liquid hair” in a bottle

  • Liquid hair is trending right now, so everyone wants shiny and smooth hair.

  • Garnier Sleek & Shine Glass Hair Water is an in-shower rinse-out treatment that reduces frizz and boosts shine to your ends.

  • Our editor tested TikTok’s famous hair treatment to see how well it works.

I’ve never had particularly shiny hair – it’s always been more curly and, as a result, a bit dull. As someone who doesn’t color my hair, I didn’t really think it was possible to get that mirror finish I see everywhere without coloring it. It was, until I noticed more and more marks release sparkles at home and shine boosters, such as Garnier Sleek & Shine Hair Water Glass ($8).

To be clear, this Garnier in-shower treatment is not a hair dye product, and you don’t need to have colored hair to use it. You just have to be someone who wants to boost the shine of her tips. The treatment promises to deliver glass hair with frizz reduction and has garnered quite a large fan base on TikTok. It’s your easy, door-to-door ticket to the liquid hair viral trend which is everywhere right now (namely, on Dua Lipa’s head, Megan Foxand Megan Thee Stallion, to name a few).

But unlike other products I’ve tried, Garnier Sleek & Shine Glass Hair Water isn’t a gloss — it uses “lamellar” technology to leave hair smooth and shiny. You can think of “lamellar” as a quick water-based hair mask. It works faster than traditional leave-in treatments to coat hair with its smoothing formula and can be rinsed out almost immediately after application.

After seeing countless people rave about it on TikTok, I tried Garnier Sleek & Shine Glass Hair Water in my morning shower routine. The instructions say to shampoo normally, wring out any excess water from your ends, then use one to two doses of the treatment. for fine hair and two to three for thick hair. Since falling into the first group, I’ve applied just under two doses to my ends. (There are markers on the back to indicate the amount of a dose, which is very useful.)

It only takes 10 seconds to work, and during that time you massage it into your hair to make sure it’s evenly coated. The bottle says you might feel a slight warming sensation (nothing too noticeable), which I felt for about three seconds. At first, it was a bit difficult to work it into my wet hair without any conditioner, but the Garnier Sleek & Shine Glass Hair Water actually provides some glide and makes my hair feel hydrated on its own. When it came time to rinse, my hair felt like it had been conditioned – it had that smooth, hydrated feel.

Like I said, I was a little wary about skipping conditioner, but my hair wasn’t as dry as I expected when I got out of the shower. The instructions say to style as desired, so I put my hair in a wrap to dry out a bit before moving on to my normal styling products. I used a volumizing mist and wave mousse on my ends before taking my blow dry brush through my hair to give me a blowout.

After styling, I immediately noticed how my hair reflected the light. He had a brilliant shine that he doesn’t usually have. My hair always gets a little frizzy when I use heat styling tools, but there was a significant improvement after using the Garnier water treatment. It was also softer and smoother to the touch. Considering it only takes 10 seconds to use and Its price is so affordable at just $8, I’d say this shine-boosting hair treatment is worthy of the attention it’s getting. I can’t wait to keep using it and see how much better my hair looks.
