The star shared her latest pick in an Instagram Reel video, in which she’s sitting down in a dressing room with her hair stylist Adir Abergel—while sporting a gorgeous bob hairstyle. “Adir and I have a secret for you—the secret to thinning hair,” she begins the video. “The biggest hair innovation for thinning hair in years and years.”

Garner then reveals a bottle of Flourish Density Booster Spray from Virtue Labs—a haircare brand that she’s been a spokesperson for since 2019. She’s a big fan of the brand, having previously raved about the Full Shampoo, Healing Oil, and Restorative Treatment Hair Mask. When it comes to this latest favorite, though, Garner says she loves the Flourish Density Booster Spray for its safe, drug-free formula that’s specifically “made for women.”


“It has been scientifically put together for a women’s head,” she explains in the video. “Everything is good in here. You can use it when you’re pregnant when you’re nursing…It’s really changing women’s lives.”

In fact, Garner shares in the video that she loves it for her own thinning hair and hair loss that she’s experiencing at 51 years old. “I would have killed for it when I was done nursing my babies and so much of my hair fell out,” she says. “I’m gonna start using it again soon because I’m of a certain age, and I want to get ahead of the shed!”

But wait—how does the spray work to help with thinning hair, exactly? According to the brand, it’s formulated with a patented healing protein that’s “clinically proven to thicken, strengthen, and revive hair.” Specifically, the botanical-based formula combines alpha and gamma keratins, which reinforce strength and provide flexibility to hair, with biomimetic signal peptides, which help to nourish and calm the scalp. Other ingredients include larchwood extract, which has been shown to stimulate hair growth, as well as a probiotic yeast extract that helps decrease scalp irritation.

And Amazon reviewers swear the product really works to combat thinning hair, with plenty who say it made their hair “thicker, stronger, and longer.” One shopper writes, “I cannot say enough good things about this Density Booster. It has truly made a difference in the appearance and feel of my hair.” Another notes, “I have thin, limp hair and since using this, it feels and looks so full and thick. It also makes my hair smell amazing which is a plus!”

Other customers love that the spray is great for new moms struggling with postpartum hair loss—just as Garner mentioned in her video. “This spray is an immediate lifesaver if you have thinning hair! It’s totally drug-free which is important to me as a nursing mom,” writes another reviewer. “This…is an awesome treatment when you begin to see your hair is a little bit thinner, especially in the postpartum period…I have seen a difference in the past several weeks with some baby hairs and regrowth!”

Given all of these glowing recommendations from customers and Garner herself, we can’t wait to get our own hands on the Virtue Flourish Density Booster Spray. And we’re definitely thankful that Garner shared her “secret” with the world—after all, as the star concludes in her own video, “You should always share your beauty secrets!”
