We purchased John Frieda's Frizz Ease Original Hair Serum so our writer could put it to the test. Keep reading for our full product review.

If you're currently seeking smoother hair—or, let’s be honest, even if you're not—you’ve likely heard of John Frieda's Frizz Ease Original Hair Serum. The award-winning product is beloved for its ability to do it all, pretty much—its formula uses dimethiconol to smooth hair, repel humidity, prevent heat damage, while ginseng extract provides more long-term healing.

I wanted to see how this fan-favorite serum would work on my own hair, so I tested it to see whether it was worth the hype. Read on for my full review.

About the Brand: John Frieda has delivered salon-quality products designed to target specific hair concerns, from brassiness to breakage and volume loss.

About My Hair: Normal but could be smoother 

My hair is mostly straight and down to my mid-back, and while I try to keep it healthy by minimizing heat and only coloring grey hairs when I need to, I have some breakage around the crown of my head (I blame it on years of wearing top knots).

Other than that, though, my hair type is pretty normal. It has a medium thickness, and while my roots get greasy after a few days without washing, my ends tend to be dry. I typically use a custom-blended shampoo from Prose, Living Proof's Perfect Hair Day Conditioner, and the occasional moisturizing hair mask when I end up with a Sephora sample. I haven’t had much success with smoothing solutions so I rarely apply other products—I rely on the hope that I’ll have a good hair day.

However, because I’d heard so much about Frizz Ease over the years but had never tried it, I decided to test it to see if it would make a difference. It needs to be applied to sopping wet hair, so I used it after showering on days when I knew I’d be heading out of the house and would want extra-smooth hair.

I liked knowing that it was protecting my hair from heat damage, and that ingredients like ginseng extract work to improve hair overtime.

The Feel: Slick and smooth

The John Frieda Frizz Ease serum feels slick, like a mixture between a gel and a silicone, and when I pump it into my hand it seems to melt.

The first time I used the product, I used two pumps (the instructions say to use one pump, but due to the length of my hair I used more) and spread it through my wet hair after showering. I didn’t notice a big difference in smoothness after drying, so the next time I used three pumps and brushed through with a wide-tooth comb to distribute it evenly. I was careful not to over-apply in any spots, and I avoided my roots, as instructed, to make sure they didn’t get too greasy. 

While I could smell the product (it smells good but strong while using!), once the serum was in my hair I couldn’t smell or feel it at all.

The Results: Well-behaved hair

While I didn’t notice much of a difference in my hair after the first use (I suspect I didn’t use enough product or distribute it evenly), when I used more product and combed it through, my hair seemed smoother than usual. It didn’t completely eliminate the stray hairs that like to pop up around my part and hairline, but it did make them much easier to control.

I also noticed that whenever I brushed my hair, it laid flat and smooth in places where it would normally continue to puff up. Because it was smoother, my hair seemed shinier, although I didn’t notice a huge boost in shine overall. I also liked knowing that it was protecting my hair from heat damage while I used a blow-dryer and that ingredients like ginseng extract were working to improve my hair over time.

I was initially worried that the Frizz Ease serum would weigh down my hair or cause it to get greasy more quickly, but even after two days, my hair didn’t feel oily or like it had a lot of product in it.

I can see myself working this product into my haircare routine for days I want super smooth, shiny hair. It can take some time to figure out how much product to use and how best to apply it, but I think those who want smoother hair will see a big difference by using this product, too.

The Value: The price is right

Part of the charm of John Frieda's Frizz Ease Original Hair Serum is the low, low price. The almost 2-ounce bottle sells for around $12, and depending on the length of your hair, the bottle should last a couple of months. While there are some options for a little less (and a lot for much more) this price—along with the fact that the product actually works—makes it worth it.

Similar Products: Something for every budget

Keratin Smooth Keratin Infusing Smoothing Serum: Even more affordable than Frizz Ease is this serum from Tresemmé, which sells for around $6 for 3 ounces. The goal of the Tresemmé serum is also silky hair, but the formula is slightly different. While both contain a few of the same ingredients, Tresemmé has keratin and marula oil instead of hydrolyzed silk and mineral oil.

John Frieda Frizz Ease Extra Strength: If the original just isn’t enough for your hair, the Extra Strength formula is made with silk extracts and seaweed extract for thick or coarse hair. It’s the same price and the same bottle size, so if you’re dealing with especially unruly hair, it may be a better option for you than the original formula. 

Final Verdict

John Frieda's Frizz Ease Original Hair Serum is a fan-favorite for a reason: It works and it’s affordable, too. The serum did a surprisingly good job at smoothing my hair (while blocking out humidity and heat styling damage) without weighing it down or feeling greasy.
