Nicole Kidman's favorite hair growth serum is a rare 25% off for Black Friday

Snag Vegamour's mega-popular formula for just $48: 'The bald spot on my front left crown is growing hair,' says one fan.

Nicole Kidman has one of the most enviable heads of hair in showbiz, so it's no wonder that luxury holistic hair brand Vegamour would enlist her as a partner and wellness advocate. After testing the collection, Kidman "found her hair undeniably transformed," saying it became thicker, fuller and "noticeably less frizzy."

One of her favorite products is the Gro Hair Serum, and it's our new favorite too — especially now that it's available at Amazon for just $48, down from $64 (that's 25% off), thanks to Amazon's Black Friday sale.

A favorite of celebs like Nicole Kidman, this top-selling serum was formulated to improve the appearance of thinning hair, leaving it looking thicker and fuller.

Why is it a good deal? 💰

Vegamour has become such a popular brand that it doesn't really need to have sales for its stuff to go flying off the virtual shelves. With that in mind, markdowns are few and far between, so if you're curious about trying Nicole's beloved serum, we recommend grabbing it while you can save.

Why do I need this? 🤔

Kidman originally discovered Vegamour during Covid lockdown in Australia, while searching for a way to revive her curls after decades of styling and coloring. Nicole landed on Vegamour as her solution, not only because it's effective, but because she supports the brand's plant-based approach to hair health. From lack of sleep and stress to vitamin deficiencies and hormonal imbalances, a multitude of issues can contribute to hair loss.

The hair serum skips the harmful chemicals and uses a blend of vegan phytoactive ingredients to help create a pro-growth environment on the scalp. It was formulated to increase the appearance of hair density while reducing signs of shedding to promote thicker, fuller-looking locks. According to the manufacturer, there's a marked improvement in as little as 90 days. One bottle is sold every 22 seconds, so it's pretty popular, and not just with Nicole.

What reviewers say 💬

With more than 2,200 five-star reviews, Gro Hair Serum is a hit with thousands of shoppers, many of whom attest that the formula helps encourage their hair's growth.

Pros 👍

"I've suffered with thinning hair due to thyroid problems, stress and medications," shared a Vegamour fan. "I started using these drops and I'm on my third bottle. My hair has thickened in the front where I had a small bald spot from stress and I have a ton of baby hairs that I'm eagerly waiting to mature. I also use other hair oils with this product and they all work together pretty well. No scalp irritation."

"It took about two and a half months before I realized that the bald spot on my front left crown was growing hair," said another customer. "I was relieved and thankful that I held out and kept using it. I have short hairs there now, which I hope will grow out. Now they just look like soft baby hair, but it's a definite improvement to the noticeable balding that was happening."

"It actually works!" gushed a convert. "I have fine hair and struggle with volume, especially on the crown of my head. I was encouraged to try this product but assumed it wouldn't make a difference. I was shocked that I could tell a difference as soon as I used it. I am hooked indeed ... simple to use and no scent which makes it that much better!"

Cons 👎

Some shoppers say the dropper could be better. "My only negative is the dropper," revealed one. "It becomes more challenging to use to the point where I either pour into another bottle or pour a little where I would have used the dropper. Otherwise, I am thrilled with the product itself."

Another shopper shared: "I know a lot of hair stuff is just garbage in the market, but I actually have way less shedding when using this product. The dropper works pretty good, sometimes a few drops fall out, but I've had worse droppers."

This popular serum doesn't go on sale very often, so snag it for less while you can!
