Thinning hair has to be one of the most frustrating haircare woes of all time. From the shedding to the breakage, watching your hair fall can lead you down a rabbit hole of late-night Google searches. While it’s always best to seek advice from a medical professional, adding a nourishing shampoo formula to your haircare routine can support your efforts to healthier strands while also providing a good cleanse.

“Your hair and scalp care regimen and theproducts that you useare the foundation of having healthy hair and, even more so, if you are experiencing hair thinning and hair loss,” saysDr. Craig Ziering, board-certified dermatologist and hair transplant surgeon.

The More You Know

Since taking our hair growth journeys into our own hands, our team has tested 32 popular shampoos for thinning hair over 24 weeks to find out which ones are actually worth the hype. Throughout this time, we considered everything from the ingredients and how they support both scalp and hair health, made note of our hair texture, volume, and density, and also considered the overall shampooing experience to find formulas that meet our high standards. As it turns out, some thickening shampoos aren’t at all gimmicky — they really work.

Keep reading to discover the best shampoos for thinning hair for every hair type and concern.

When testing this Briogeo shampoo, ourtesternoticed a change in the appearance of volume almost immediately, and with regular use, her hair felt thicker, too. We also saw regrowth in areas of concern after just a few weeks.

While it is on the pricey side (especially for only eight ounces), the results are well worth the investment. Plus, a little bit of formula goes a long way, so you may not run out of this bottle as fast as you think.

What We Think NowAfter using the Nioxin shampoo for six months, our tester noticed that she could get away with washing her hair less often, and in turn, maintained voluminous hair styles for longer than before. This shampoo made her dye-damaged hair feel healthier and thicker, too, which helped her hair look less flat between washes.

Throughout the testing period,they also noticed how much fuller their hair lookedand that styles would have longer hold and even a bit of bounce — no doubt a result of the shampoo’s hydrating and health-enhancing ingredients. While it is a bit expensive, we found that a quarter-sized amount lathers nicely and can take you a long way.

The only downside is that the bottle is pretty small, so we had to purchase another one after about two months.

Our tester used this shampoo to combat postpartum hair loss and found that it did an excellent job of strengthening strands, resulting in less breakage (though she wished it helped control frizz a bit more). The shampoo also had a nice lather so it was easy to suds up in her hair and hands. Despite producing a good amount of bubbles, it was super easy to rinse out, leaving hair feeling ultra-soft and deeply cleansed.

What We Think NowThe quality of the Shu Uemera shampoo did not wane over our six months of testing and made our hair look full, thick, and healthy. The shampoonoticeably reduced hair breakageand helped our hair to grow faster than before. While it didn’t do much to extend our styles in between washes (that’s where theR+Co shampooreally shined), we’d still recommend this shampoo for anyone who wants a strengthening shampoo that smells great and delivers on its promises.

This reasonably-priced shampoo has a lot of shiny qualities that extend past its pretty price — including the fuller and longer hair growth that we noticed, the glossy finish that it gave our strands, and its frizz-controlling properties that kept our hair looking sleek after every use.

What We Think NowOur tester noticed pretty dramatic results after continuing to use the Mielle Rosemary shampoo for six months. After two months, their hair felt healthier and looked fuller, and four months after that,it shed less during wash daysand felt clean and hydrated. They ran out of this shampoo after almost three months of using the shampoo twice a week, and for just $11 a bottle, which makes it an incredible value for the quality.

After the test is complete, you’ll end up with a slew of products and suggested supplements in order to achieve the hair of your dreams. We noticed a significant change in the strength and overall health of our hair within the first two weeks of testing our personalized shampoo and conditioner.

Since you can’t just walk into the store and buy this customized shampoo, you’ll need to be proactive about ordering a new shampoo when the time for a restock is coming close (or you can subscribe and save for 15 percent for routine deliveries). However, we think the personalized formula is worth the extra work.

“I had a theory that finding the ‘right shampoo for you’ might reduce hair loss more than a general shampoo specifically targeting hair loss, so I called in a sample of Prose custom haircare after Instagram bombarded me with it. I think my theory is correct, because my hair is healthier and more hydrated than it’s been in years, and, as a result, I’ve noticed less hair going down the drain at the end of my showers.” —Erin Johnson, associate editorial director

Other Shampoos for Thinning Hair We Tried

Experts SayDepending on the cause of hair thinning, strands can definitely grow back after thinning. “With proper care, a healthy routine, and professional treatments, thinning hair can improve in density and volume,” says Dr. Sobel.However, in order for hair to grow back, Sobel says identifying the cause is most important as this can inform the best treatment. And, while shampoos for thinning hair can certainly support healthier hair, they might not target thinning hair on their own as some causes of thinning hair require medical attention in order to truly reverse.

What to Know About Shampoos for Thinning Hair

Stimulating Ingredients

Just like withhair loss treatmentsandmasks and conditioners for hair growth, the ingredients in a shampoo formula matter and this couldn’t be more true for those designed specifically with thinning hair in mind.

“Disinfectant molecules such ascarnosic acid from rosemary or terpinene-4-ol from tea tree oilhelp to control microbial overgrowth and promote good bacteria so that the balding scalp is free from issues of bad microbes,” saysDr. Sanjay Batra, a hair loss, and regenerative expert and co-founder of WeThrivv. “If your shampoo contains these disinfectant ingredients, it will become a medicine for your scalp.”

Additionally, Dr. Ziering recommends looking forbiotin and caffeinein your shampoo formula, as these can support scalp health while also strengthening and revitalizing the strands.

Our top pick for the best shampoo for thinning hair, theBriogeo Destined for Density Peptide Shampoo, features caffeine in its ingredient lineup, as does thesuperzero Strengthening & Scalp Stimulated Shampoo for Thinning Hair.

Consider Your Hair Type

While many thickening shampoos are formulated for those with thin or fine hair, it’s important to asses your individual hair type and condition of your scalp (most vary between normal, dry, or oily). This can ensure that your roots receive the nutrients and care they need, whether that be oil control or light hydration that won’t weigh down strands.

To find the best shampoos for thinning hair, we researched dozens of formulas before selecting 32 products for real-world testing. From there, our PEOPLE Tested team conducted at-home tests over the course of six months, carefully documenting their experiences with every wash. To make sure we only recommend the best, we continue to test products on the market and update this story accordingly.

In order to determine which shampoos still deserved a place on our list, we looked at the following qualities:

Jessie Quinnis a contributing writer for PEOPLE and has written for publications such as Byrdie, InStyle, The Spruce, NYLON, and more. When covering the best shampoos for thinning hair, Jessie researched each formula on the PEOPLE Tested team’s list and carefully reviewed their notes to learn more about their experiences. She looked for formulas that not only gave impressive results for hair density and volume but also looked at additional perks like shine and improved texture. Additionally, Jessie reached out to top haircare experts Dr. Craig Ziering, Dr. Sanjay Batra, and Dr. Howard Sobel to learn more about shampoos for thinning hair, including what to look for and what to know about the potential benefits.
