Nicole Kidman’s favorite hair-growth serum is on rare markdown at Sephora's Beauty Insider Sale

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. If you're curious about trying her go-to products — namely, the popular Gro Hair Serum — Rouge members can snag it for 20% off during Sephora's early-access Beauty Insider Sale. After testing the collection, Kidman "found her hair undeniably transformed," saying it became thicker, fuller and "noticeably less frizzy." The actress discovered Vegamour during lockdown in Australia while searching for a way to revive her curls after decades of styling and coloring.

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

Why is this a good deal?

Markdowns on Vegamour products are few and far between, so if you're curious about trying Nicole's beloved serum, we recommend grabbing it while you can save nearly $13. Plus, the Beauty Insider Sale is sitewide for Rouge members thanks to early access, so you'll get 20% off nearly anything you buy.

Why do I need this?

Nicole landed on Vegamour 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. With this in mind, Gro Hair Serum skips harmful chemicals and uses a blend of vegan phytoactive ingredients to help create a pro-growth environment on the scalp.

The serum was formulated to increase the appearance of hair density and reduce 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 of the serum is sold every 22 seconds, so it's pretty popular, and not just with Nicole.

What reviewers say

Vegamour Gro Hair Serum is a hit with Sephora shoppers, and more than 1,000 give it five stars.


"Myself and my hairdresser have noticed way more growth in my hairline, and my hair has grown double the length in six months, which is not normal for me," gushed a fan.

"I have been using this product for one month now and have noticed so many new hairs and felt like it had already made my hair thicker," said a happy customer. "I went on Accutane and since then my hair has been thin and I was struggling with hair loss — but I feel like I'm now finally making progress, and it's all due to this serum!"

"I personally love this product," raved another devotee. "It smells heavenly and I feel like my hair has become so much thicker since using it!"

"OK — I have tried numerous things such as castor oil, biotin, masks, treatments and I could never see a change and disclaimer: I'm consistent when using/applying products," wrote a convert. "This serum is nothing but wow: texture, ease of application, the way it doesn't leave your hair looking greasy and, most importantly, the result. I have so much new hair growth, my hair definitely feels fuller when I put it in a ponytail. Ladies, run, don’t walk, and get it. Make sure you are consistent and results won't make you wait long."


Users say not to expect Rapunzel-level locks overnight: "You have to be patient to see your results because sometimes what is happening is step by step," advised a reviewer. "I used for three months, and it absorbs quickly and smells good. I see the difference in my hair, like it's denser and it's grown."

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