While thinning hair can be a shock to the system, everyone experiences hair loss to some extent. In fact, most people shed somewhere between 50 and 100 hairs a day, says Brendan Camp, MD, a board-certified dermatologist and dermatopathologist. If you find yourself suddenly losing more hair than usual or feel like your hair is becoming much thinner than you’re used to, a quality shampoo for thinning hair can restore thickness and volume in a pinch. Thinning hair can have many causes, including aging and changing hormones. While seeing an expert is always your best bet to identify underlying causes and find a solution, a shampoo with specific ingredients to boost hair growth, strength, and thickness is a great place to start.

To help you find the right product, we spoke to experts and tested 21 popular shampoos. We carefully evaluated each product based on criteria such as ease of use, effectiveness, cleansing ability, scent, and overall results. These are our top picks.

To improve the length, thickness, and strength of your hair, look for ingredients like niacin, biotin, saw palmetto, and rosemary oil as they help drive blood circulation to the scalp and promote growth. Likewise, histidine, ceramides, and keratin nourish your strands and resist damage.

Stay away from harsh ingredients like sulfates, phthalates, and anything else that strips your hair of natural oils. These ingredients can cause dryness, brittleness, and breakage.

Lathers well and leaves hair feeling clean

Improves hair strength and volume

Smells great

Slight tingling sensation

Strong scent may be overpowering for some

Key Ingredients: Tea tree, Kakadu plum, pea peptides, clover flower, turmeric, ginseng | Size: 10.14 fluid ounces | Color Safe: Yes

Paul Mitchell’s Tea Tree Scalp Care Regeniplex Shampoo thickens hair in two ways: it renews scalp health and makes hair feel stronger and fuller. These are ideal benefits to look for if you notice hair thinning, says Garshick. While the ingredients won’t directly impact your hair loss, they will help your hair appear fuller and healthier while you wait for new growth to come in.

This shampoo checked all our boxes. The powerhouse ingredients made our hair more voluminous and shiny, leaving our hair and scalp feeling clean and refreshed. We also love how fast-acting this pick is. It was so effective that we noticed less breakage and hair fallout from the first shower. Plus, the tea tree gives off a clean, invigorating smell with every use.

The powerful scent of tea tree oil might be too strong for those sensitive to smells. It can also cause a tingling sensation on your scalp, irritating some people.

A little goes a long way

Improves hair volume

Hair looks smoother and shinier

Doesn’t lather as well as others we tested

Strong scent may be overpowering for some

Key Ingredients: Biotin, caffeine, copper peptides, zinc | Size: 8 fluid ounces | Color Safe: Yes

A favorite among the experts we interviewed, Briogeo Destined for Density Peptide Shampoo is full of ingredients that boost hair growth and strand thickness. The caffeine in this shampoo is perfect for increasing blood flow and oxygen to the scalp, says Camp. Additionally, biotin is great for nourishing hair. It made ours smoother and shinier during testing.

If you suffer from dandruff and flaking, this shampoo is a great choice. It contains zinc, which is known for reducing scalp scaling and itchiness. We noticed our normally dry scalp looked and felt better between washes.

One of our editors noted this shampoo scent made her feel like she’s “been galloping in a field of daisies,” but the strong floral scent may not be something everyone enjoys. It also didn’t create as much of a lather in the shower as other shampoos we tried, although our hair still felt clean after use.

Reduces hair fallout

Improves shine and reduces frizz

Great, mild scent

Doesn’t lather as well as others we tested

May need to wash twice to get that really clean feeling

Key Ingredients: Aloe vera, peppermint, rosemary, saw palmetto | Size: 10.14 fluid ounces | Color Safe: Yes

The proprietary blend of ingredients in BondiBoost HG Shampoo for Thinning Hair, which includes aloe, peppermint, rosemary, and saw palmetto, will help you battle thinning hair and protect against environmental stressors. It’s also free of sulfates, which are important to avoid as they can dry out your hair, leading to a brittle feeling and more breakage, says certified trichologist Tiffany Young.

We noticed less hair fallout in the shower and when brushing while testing this shampoo. It also left our hair bouncy and full, and we could even go longer between wash days. This gentle shampoo has a delicious, mild scent of rosemary and peppermint. It reduced frizz and left our hair shinier and softer without causing any issues, even on an oily scalp. The best part? We noticed these results after just a couple of washes.

This might not be the pick for you if you prefer a shampoo that lathers up a lot. We had to use a decent amount of product to get a good lather, and even then, it wasn’t very sudsy. Along the same lines, we sometimes needed to shampoo twice to get that squeaky clean feeling.

Strengthens hair

Hair looks noticeably shinier

Lathers well and leaves hair feeling clean

Takes consistent use to notice a real difference

Key Ingredients: Rice water | Size: 10 fluid ounces | Color Safe: Yes

We appreciated how much stronger Shu Uemerua Izumi Tonic Strengthening Rice Water Shampoo made our hair feel during testing thanks to its key ingredient—rice water. Rice water is the starchy water that comes from cooking or soaking rice, and it’s known for being full of vitamins and nutrients. Young recommends it for strengthening strands and preventing breakage, and we noticed these benefits once we incorporated this shampoo into our routine. As an added bonus, our scalp started filling in with new growth.

This shampoo is particularly gentle on thinning hair. It takes little scrubbing to lather, but the lightweight formula won’t weigh hair down and can also help reduce split ends.

We didn’t see much difference in overall thickness or volume. Also, if you’re looking for fast results, this might not be the product for you. Another gentle option that's fast-acting and mild enough for daily use is Arkive Headcare All Day Shampoo. The combination of baobab protein and baobab oil moisturizes while cleansing, making our hair shinier, less frizzy, and more resilient. We had a noticeable reduction in breakage and shedding and started to see promising new growth along our hairline near the end of testing. The only downside is that it doesn't lather as much as other options during use.

Improves hair volume and shine

Helped us stay go longer between hair wash days

Gentle on scalp

Didn’t reduce frizziness

Takes a bit more effort to fully wash out

Key Ingredients: Tiger herb, coconut, aloe | Size: 8.5 fluid ounces | Color Safe: Yes

Fable and Mane HoliRoots Hydrating Shampoo added tons of moisture back to our damaged, thinning hair. Despite the deep hydration it gave us, our hair still felt lightweight and looked more voluminous after every wash. It was also gentle and left our hair looking shiny and healthy. Plus, we could go longer between hair wash days than usual.

The ingredients in this pick are unique among the other products on this list. It’s important to note that this sulfate-free shampoo focuses more on soothing and moisturizing your hair and scalp to support growth rather than thickening or strengthening. However, this works to your benefit by preventing brittleness and breakage, a primary concern for those with thinning hair.

Getting a good lather going with this shampoo can take a lot of product and water. In turn, washing out can be a little tedious, especially if you have thick or curly hair. And while it was definitely hydrating, it didn’t tame our frizziness.

Strengthens and thickens hair

Improves shine and reduces frizz

Peppermint smell might not be for everyone

Takes consistent use to notice a real difference

Key Ingredients: Peppermint oil | Size: 16.9 fluid ounces | Color Safe: No

Nioxin Cleanser Shampoo System 1 was a top choice among our experts, who praised its use of proteins, amino acids, and antioxidants for strengthening hair. Garshick notes that if used with the full Nioxin System 1, this shampoo makes the perfect base for an effective hair and scalp treatment. However, even using the shampoo alone had us swooning over our thicker, fuller hair.

This invigorating peppermint-scented shampoo gave us stronger hair, and we noticed a lot less breakage throughout the testing period. It greatly improved our hair’s shine and reduced frizz. Formulated to purify the scalp before using the other System 1 products, this shampoo easily cleared oil and product build-up and helped our hair grow long and strong.

While some of us love minty scents, the strong peppermint smell of this shampoo might not be a hit for everyone. It’s also worth noting that this shampoo isn’t formulated for colored hair. If you have colored hair and you’re looking for something similar, Nioxin’s System 3 is made particularly for colored thinning hair.

Improves hair volume

Hair looks fuller and thicker

We saw new hair growth in thinner spots

Minty smell might not be for everyone

Using a shampoo bar can take some getting used to

Key Ingredients: Triolein, vegan keratin, caffeine, rosemary oil, menthol, amla extract | Size: 2.15 ounces | Color Safe: Yes

The only shampoo bar on our list, the superzero Strengthening and Scalp Stimulating Shampoo Bar greatly improved our hair volume and thickness. Thanks to ingredients like caffeine and rosemary oil, our scalp felt clean and our hair felt stronger after a few weeks of use. One of its ingredients, rosemary oil, is especially beneficial if you’re suffering from hormone-related hair loss, Young says.

We weren’t familiar with using a shampoo bar, but we found that this one lathered easily with little effort on our part. By the end of testing, this sulfate-free shampoo made our hair full and voluminous. We also saw new hair growth in spots where our hair had been particularly thin.

The minty smell of this shampoo bar might irritate those with sensitive noses, but we found it fairly mild compared to other minty shampoos we’ve tried. And, if you’re new to shampoo bars, it can take a few washes to get the hang of it.
