No one wants to experience hair loss, but it happens. Medical conditions, hormonal imbalances, medications and aging are a few factors that can contribute to hair thinning or loss.

Many companies sell hair loss products promising to give you a head full of hair, but it can be hard to decipher which ones are actually worth your money.

Nioxin® is a brand you may have encountered while searching for hair loss treatments. The company makes hair care products, such as Nioxin shampoo, cleanser, conditioner and hair loss “system kits.” 

Nioxin’s hair products are formulated specifically for thinning hair, and most make bold claims about their ability to reduce hair fall, prevent breakage and increase thickness. 

The brand also offers science-based hair loss medication.

Slick marketing can make it difficult for consumers to see past flashy ads and figure out what products are truly effective. But don’t stress — we’ll help you make the best decision for your hair type.

Below, we’ll look into Nioxin’s offerings for hair loss and thicker hair, discuss which products might not be worth the hype and go over other treatment options to consider.

Nioxin was founded in 1987 by Eva Graham. The company sells hair care formulations and scalp treatment products.

Graham was motivated to create Nioxin when she experienced hair loss after giving birth. She partnered with biologists, chemists, pharmacologists and hairdressers to create hair loss products with herbs and botanicals.

Throughout the 90s and 2000s, Nioxin’s products became popular non-drug alternatives for promoting fuller hair. In 2008, the brand was acquired by the consumer giant Procter & Gamble, joining other hair care brands such as Head & Shoulders and Wella. 

Nioxin’s range of hair care products is extensive, with more than 50 hair loss shampoos, leave-in conditioners, scalp treatments, oral supplements and other products to choose from.

  • Nioxin hair care products. These include shampoo, conditioner, leave-in treatments, hair growth vitamins and other products designed to keep your hair in optimal condition and stimulate healthy growth. 

  • Nioxin system kits. These contain multiple products designed to prevent hair thinning, strengthen, stop breakage and remove dirt, oil build-up and other residues.

  • Nioxin hair styling products. These include gel, hairspray and mousse formulated to boost hair volume and give hair a thicker, fuller appearance. 

  • Nioxin hair growth medications. These contain minoxidil in 5% form for men and 2% for women. Minoxidil is the active ingredient in Rogaine®, a well-known medication for stimulating hair growth.

Our article on Nioxin versus Rogaine goes over the differences between the two.

Are Nioxin hair loss products effective for conditions like male pattern baldness? Some work, and some don’t.

Before we break down the effectiveness of the products, we’d like to point out that brand names aren’t that important for growing hair and maintaining a healthy scalp. Active ingredients are what really matter.

Nioxin Hair Care Products

Nioxin’s shampoo, conditioner and leave-in treatments form the core of its hair system kits. The brand recommends using all three products together to promote thicker, denser-looking hair.

Nioxin hair care products contain a few key ingredients: saw palmetto, peppermint oil, vitamin B5 and niacinamide.

These ingredients are linked to improvements in hair growth. For example, one study involving 50 males aged 20 to 50 with androgenetic alopecia showed that saw palmetto increased average hair count over 24 weeks. 

Saw palmetto is a berry extract that may reduce local dihydrotestosterone (DHT) levels. Your body produces DHT as a byproduct of testosterone.

DHT plays a vital role in the development of male features, like genitals and facial hair. It’s one of several hormones that make males, well…male. But over time, DHT can cause hair follicles to spend less time producing new hairs, leading to thinner, shorter follicles.

A study involving 60 participants with female pattern hair loss showed that topical niacin — a category including niacinamide — significantly increased hair fullness over six months. However, we don’t know the dosage amount or frequency used.

Some Nioxin hair care products may relieve an itchy scalp. While an irritated or dry scalp doesn’t directly cause hair loss, itching your scalp may damage strands and contribute to brittle hair. Our blog discusses the connection between itchy scalp and hair loss.

Nioxin’s hair care products may improve the look and feel of your hair, but they aren’t the be-all and end-all for improving male pattern baldness. Also, on a side note, some of Nioxin’s products contain ingredients like sulfates, which can affect the amount of protein in your hair follicles. 

Nioxin Hair Styling Products

Nioxin also sells several hair styling products specially formulated for people with thinning or fine hair. These products can help you style your hair while adding volume.

Now, if you want products that’ll help grow your hair, these shouldn’t be your go-to. Nioxin recommends using its minoxidil treatment (we’ll get to this next) and system kits first for hair loss. The styling products are just a volumizing bonus.

Nioxin Hair Medications

Nioxin has a medicated hair regrowth treatment containing minoxidil, a hair growth stimulator for men and women. Minoxidil works by shortening the telogen phase of the hair growth cycle (when hairs shed). In turn, the anagen (growth) phase is longer.

Minoxidil can be an effective active ingredient for hair growth products. In a study with about 900 male participants, 62 percent had noticeable hair growth after using the topical medication for 12 months.

Learn more in our guide to applying minoxidil for hair growth.

Are the products sold by Nioxin good for hair? Like any company, Nioxin for hair loss has its benefits and downsides. 

We’ll save you some time reviewing countless YouTube and Google reviews by giving you all the pros and cons of using Nioxin.

Here are a few benefits of using Nioxin:

  • Nioxin is somewhat effective for hair loss. Based on the active ingredients previously mentioned, Nioxin’s hair care products can help stimulate hair growth to a degree.

  • There’s a wide variety of products. Nioxin can be a one-stop shop for all your hair care needs if you have hair loss or hair thinning problems. From peppermint shampoo to hair gel, the company has a wide selection of products to choose from.

  • The products are simple to use. You don’t have to be a rocket scientist to use Nioxin’s products. The brand provides easy-to-follow instructions for its topical minoxidil solution.

These are the potential drawbacks of using Nioxin:

  • Results don’t last long. Unfortunately, clinical trials have shown that Nioxin’s hair regrowth treatments don’t last longer than 48 weeks.

  • Products are expensive. Depending on your budget for your hair care regimen, Nioxin products may put a dent in your wallet. Prices start at $30. 

  • Once you stop using the products, you can lose new hair. If you stop using Nioxin minoxidil treatment, your hair may fall out in three to four months.

Individual results will vary. Customers were given free product.

While Nioxin has an extensive line of hair care and treatments for hair loss and thinning, it’s not the only maker of effective products.

And if you’re dealing with male pattern baldness (androgenetic alopecia), Nioxin alone won’t be effective enough for treating the condition. Men with signs of hair thinning, a receding hairline or other early signs of hair loss might want to consider the following hair loss treatments.


Finasteride is a medication approved by the U.S. Food and Drug Administration (FDA) to treat male androgenetic alopecia. 

A study involving over 500 Japanese men with male pattern baldness showed that a 10-year daily treatment of finasteride was highly effective in improving symptoms. 

Finasteride was formerly sold as Propecia® but is now available as a generic medication. Don’t want to see a dermatologist in person? We offer finasteride online, following a virtual consultation with a licensed healthcare provider who’ll determine if a prescription is appropriate.


Biotin (vitamin B7) is an essential nutrient found in some foods and available as a dietary supplement, such as biotin gummies

When you’re biotin deficient, you can develop thinning hair that progresses to hair loss across your body. In that case, taking biotin could help promote healthy hair, but we don’t recommend relying on this supplement as your only treatment.

Other DHT-Blocking Shampoos

Many companies (beyond Nioxin) make shampoos and conditioners that block DHT and prevent hair loss.

These products often contain ketoconazole and saw palmetto to help wash away follicle-clogging sebum and promote healthier hair. If you have issues with dandruff, ketoconazole can be a great dandruff detox shampoo.

Our thickening shampoo with saw palmetto helps boost volume. Our guide to DHT-blocking shampoos goes into more detail about how these products can help prevent shedding and maintain a healthy head of hair. 

If you feel like your hair’s a little flat, try our volumizing shampoo and volumizing conditioner.

Other Minoxidil Treatments

Nioxin’s hair regrowth treatment contains the medication minoxidil. We also offer minoxidil products with minimal side effects.

If you’re experiencing hair loss or thinning, our topical finasteride & minoxidil spray, minoxidil foam or liquid minoxidil solution might be the ticket to your best hair ever.

Hair loss treatments, delivered

Nioxin’s hair care products and hair regrowth treatments could be worth a shot if you’re dealing with mild hair loss and thinning.

However, if you have severe male pattern baldness, it’s better to seek alternative hair loss treatments that have shown to be more effective.

In the end, the choice is yours. Use products that work for you, and keep this in mind:

  • Nioxin is a line of hair care products. Its offerings include FDA-approved topical minoxidil solution.

  • Other active ingredients in Nioxin products include saw palmetto, peppermint oil, vitamin B5 and niacinamide.

  • Some of these have limited research showing improvement in hair growth, but minoxidil is the only Nioxin ingredient proven effective for hair loss treatment.

  • Alternatives to Nioxin include finasteride, biotin, DHT-blocking shampoos and minoxidil treatments from Hims.
