Nicole Kidman, Jennifer Garner, and More Stars Rely On These Hair Growth Picks — From $24

I always welcome a second opinion before I buy new items. That’s why I often turn to celebrities for all sorts of recommendations, from comfy sneakers to skincare products. Because let’s be honest — online shopping can be a hit or miss. Now that I’m obsessed with reviving my thinning strands, I’m taking suggestions from a few Hollywood stars. 

Jennifer Garner, Nicole Kidman, Alyssa Milano, and Sharon Stone are all no strangers to hair loss. Fortunately, they haven’t been shy about it, either. If you want to rescue your thin strands as well, I’ve got you covered. I’ve compiled the shampoos, leave-in treatments, and spray formulas these actresses swear by for thicker, stronger, and healthier hair. Check out these celeb-approved hair growth products starting at $24, below.  

4 Celebrity-Used Hair Growth Products

Vegamour Gro Revitalizing Shampoo

Nicole Kidman is a huge fan of Vegamour’s hair growth shampoo, conditioner, and serum which she dubbed her “personal favorites,” in a 2023 press release. The Gro Revitalizing Shampoo, in particular, is a go-to for my thinning hair as well, thanks to its plant-based ingredients (such as caffeine, peptides, biotin, and a keratin alternative) which prevent breakage and add fullness to my hair. 

Nioxin System 1 Shampoo

Nioxin offers a handful of hair growth formulas which I swear by as well for a denser-looking mane. And it turns out, Alyssa Milano also raves about the Nioxin System Kit 1 (which includes a shampoo, conditioner, and spray) which “helped tremendously” when it came to hair loss after a Covid-19 case. It utilizes caffeine, peppermint oil, and niacinamide to tackle light thinning.  

Virtue Flourish Density Booster Spray 

Jennifer Garner called the Virtue Flourish Density Booster Spray her “secret” to treating thinning Hair. It’s made with the brand’s signature ingredient, Alpha Keratin 60KU, which mends bonds and improves elasticity to prevent breakage. Along with this, it contains soothing probiotics which increase blood flow in the scalp along with peptides which boost collagen production to stimulate hair follicles, promoting new, thicker strands. While you’re at it, shop the brand’s shampoo, conditioner, and hair mask, too. 

Augustinus Bader The Leave-In Hair Treatment

A slew of Hollywood stars love to use Augustinus Bader’s skincare products. But for Sharon Stone, the luxurious brand’s hair care line is a must for her beauty routine. The actress revealed that she “grew back” all the hair she lost after a stroke thanks to Augustinus Bader’s shampoo, conditioner, and the leave-in hair treatment. This strengthening formula supports keratin production to improve hair’s thickness, shine, and hydration.
