Has your once-thick hair started to feel a little finer and or flatter? Thanks to hormone changes and an aging scalp, many women experience noticeable hair thinning by age 50. Here’s the good news: You don’t need a pricey salon visit or a splurge-worthy serum to give thinning hair a boost. A regular Costco run can do the trick. The warehouse’s beauty aisles are packed with affordable shampoos, conditioners and masks—even dupes of pricey products!—designed to strengthen strands, revive volume and reduce breakage while saving you money. Here are five standout Costco hair growth products worth adding to your cart.
Costco hair product dupes and deals that boost growth
For fuller, thicker, healthier hair, give these Costco bargains a try.
Kirkland Signature Minoxidil Hair Regrowth Treatment—$48.99

If you’ve looked into minoxidil for hair regrowth, you’ve probably eyed Rogaine. The men’s version is typically cheaper than the women’s one (despite having the same active ingredients), yet it can still cost about $50 for three 60-gram bottles. That’s where Costco’s budget-friendly dupe can help you save big. The Kirkland Signature Minoxidil Hair Regrowth Treatment for Men uses a similar formula—both are 5% minoxidil topical solutions—and costs $48.99 for six 2 fl. oz. bottles (twice what you’d get with Rogaine). That’s the same active ingredient for roughly half the price.
Pura D’or Advanced Therapy Anti-Hair Thinning Shampoo and Conditioner Set—$39.99

This Pura D’or duo comes in hefty 24-ounce bottles ($39.99 for a set of shampoo and conditioner) and promises a noticeable increase in volume, strength and thickness while reducing thinning and hair fall. The strengthening ingredients include argan oil and biotin, and Costco shoppers rave about the combo.
“I love this product. It’s the first time I’ve actually felt my hair improve with a particular product. My thin hair feels healthier, it’s longer and it’s definitely not frizzy anymore. My husband has commented many times on my ‘good hair days,'” one happy customer wrote in the reviews.
Kirkland Signature Moisture Shampoo—$11.99

Heard rave reviews about Pureology’s Hydrate Shampoo, but can’t stomach the whopping $90 price tag for a liter bottle? Costco has a dupe that helps hydrate dry strands to reduce the breakage and hair fall that can become more common with age, and it’s a tiny fraction of the price. The Kirkland Signature Moisture Shampoo costs just $11.99 for a liter—that’s more than 86 percent off the retail price of Pureology’s version. One note: Some reviewers say that since Kirkland reformulated the shampoo, it’s not as similar to Pureology’s version. Still, for that price it’s worth a try!
Dr. Groot Scalp Revitalizing Solution Shampoo—$54.99 for two

Healthy hair starts at the scalp, and this Costco pick works from the root. The two-pack of Dr. Groot Scalp Revitalizing Shampoo contains biotin to strengthen the keratin in hair and prebiotics to nourish strands. The brand claims it can improve hair thickness in two weeks and reduce breakage-related hair loss by up to 82 percent.
BondiBoost Intensive Anti-Thinning Shampoo, Conditioner and Hair Mask—$39.99

This BondiBoost hair-growth bundle delivers a spa-like sensation with serious growth ingredients. The shampoo contains natural rosemary and peppermint to stimulate the scalp, plus Redensyl and Procapil—two ingredients specifically targeted at hair growth. The matching conditioner adds saw palmetto to the rosemary-and-peppermint blend. Plus the hair mask treatment reduces split ends so that hair can grow longer and stronger.
“Love how this feels on my scalp. It smells divine and makes my scalp feel so clean and refreshed. There’s a tingling sensation which I think is from the peppermint. I’ve also seen less hair breakage. Would recommend!,” one happy customer shared.
The bottom line on Costco deals and dupes for hair growth
You don’t need to spend a fortune at high-end salons or settle for less-than-luscious locks. These budget-friendly Costco finds are proof that beautiful, healthy, thicker-looking hair is absolutely within reach—and your next warehouse run could be the start of your hair transformation journey.
