A Shopper’s ‘Hair Loss Was Cut In Half’ Thanks to These 11 On-Sale Growth Treatments

I can tell the group chat is evolving along with the candles on my birthday cake because lately, the pressing questions are about hair growth. It starts with: Does everyone else feel like their ponytail has gotten smaller? Then, spirals into: I’m noticing a lot of extra hair in the drain. And finally comes: Should I be taking vitamins for hair loss? Or has anyone tried a hair growth serum that actually works?

Hair loss has many causes, and hair growth is a complex process, which means the solutions come down to trial-and-error and a lot of patience. However, we can make it easier: The Shape team has tested, researched, interviewed experts, and combed through hundreds of reviews to find the best products. Shop 11 hair loss treatments that actually work and are on sale for Black Friday — starting at just $8. 

Best Overall Hair Growth Deals

Mielle Organics Rosemary Mint Strengthening Shampoo

Rosemary oil for hair growth is the topic du jour this year with viral TikTok videos of results and experts weighing in on its effectiveness. Some research shows that rosemary oil may be as effective as minoxidil, a popular ingredient for growth. Fans of the now-$8 Mielle shampoo say that it “revitalizes and strengthens hair with every wash.”

Keranique Hair Regrowth Treatment for Women

Users of this twice-a-day treatment saw new growth in four weeks. The two-percent minoxidil-based formula and precision spray applicator makes it easy to deposit the product where you need it most. One cancer survivor said a year later, and her hair is “as thick as it was before cancer.”

Vegamour Gro Hair Serum

Vegamour is a favorite among the Shape staff and Nicole Kidman. Better yet, the site is 30 percent off for Black Friday. One staffer used the serum for 18 months and raved about her results. There’s several ingredients that make this serum special, namely, mung beans and red clover, which nourishes the scalp and nicotiana benthamiana, whose plant proteins help increase the density of roots. 

Kitsch Rosemary & Biotin Volumizing Natural Shampoo Bar

While the growth-promoting ingredients would suggest a higher price point, one Kitsch bar is on sale for $11. It includes biotin, which is known for its ability to support keratin production, and rosemary oil to help strengthen and thicken the appearance of hair over time.. 

Rogaine 5% Minoxidil Foam

Minoxodil, a gold standard for hair growth, according to many dermatologists and research studies is the hero ingredient in this Rogaine foam treatment. The once-a-day treatment helps treat hair loss and jumpstart the process for new growth. One reviewer called it a “miracle foam,” saying, “I started using the Rogaine and it gradually thickened up my hair.”

Pura D’Or Original Gold Label Anti-Thinning Biotin Shampoo

Hair growth that’s as easy as sudsing up in the shower? Sign us up. That’s the process for Pura D’Or Anti-Thinning Shampoo: Daily (or as often as you wash your hair), use this product packed with hair growth oils to increase strand volume and thickness. 

Divi Scalp Serum

The 1,300 five-star reviews convinced us this was a serum to tell the group chat about. A mix of hair follicle-stimulating ingredients, such as amino acids, caffeine, and rosemary oil, help to reduce the appearance of thinning hair. A happy shopper said, “I’ve noticed less dryness and irritation…and it’s definitely supporting my hair growth.”

Virtue Flourish Density Booster 

Formulated to prevent hair loss, as well as fuel regrowth, Virtue Density Booster is a botanical solution for thinning hair. Once a day, on damp or dry hair, spray directly onto the scalp, massage, and do not rinse. Reviewers on the Virtue website called it “volume and body in a bottle” and said it “helped thinning hair look and feel fuller.”

Nutrafol Conditioner

The brand that brought us hair growth supplements, also has an effective topical line targeting hair loss. The conditioner is a fan-favorite since it’s moisturizing and safe for color-treated hair. “I love how this product has helped my hair shine, with thickness and overall health,” explained one reviewer. While pricier than some conditioners, many testers say a little goes a long way (and a sale helps, too!). 

Viviscal Hair Thickening Serum

This was a top pick in our hair growth serum testing, with our editors saying they had noticeable fullness and appreciated the seamless application process (the watery texture can be applied to wet or dry hair from mid-shaft to ends). This sentiment was mimicked by Amazon reviewers, with one shopper saying their hair loss “was cut in half.”

The Nue Co. Supa Thick Hair Growth Topical Hair Supplement 

What’s good for your gut is also good for your hair — the pre- and probiotics in the Supa Thick serum target your scalp’s microbiome to create an optimal environment for growth. One reviewer was really impressed with their results after three weeks, saying, “I noticed baby hair regrowth at my temples. My hair is no longer itchy or dry, as well.”
