Many hair loss products promise to give you a head full of hair, but it’s not easy to tell which ones are actually worth your money. Nioxin® is a brand you may have encountered while searching for hair loss treatments — but does Nioxin work?

Nioxin offers a range of products specifically targeting thinning hair, including shampoo, conditioner, and medications. The brand markets these products primarily to people with female and male pattern hair loss (androgenetic alopecia). 

Nioxin makes bold claims that the products can reduce hair fall, prevent breakage, and increase thickness. But is all this true?

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

Nioxin is a hair product company that offers hair care formulations and scalp treatment products. 

The company was founded in 1987 by Eva Graham, who says she was inspired to start Nioxin after experiencing postpartum hair loss.

Throughout the ‘90s and 2000s, Nioxin’s products became popular non-drug alternatives for promoting fuller hair. In 2008, Procter & Gamble acquired the brand.

Nioxin’s range of hair care products includes more than 50 hair loss shampoos, leave-in conditioners, scalp treatments, and oral supplements.

Their product range includes:

  • Nioxin hair care products. These include shampoos, conditioners, leave-in treatments, and other products designed to keep your hair in optimal shape and stimulate healthy growth.

  • Nioxin system kits. These contain multiple products to prevent hair thinning, strengthen weakened strands, stop breakage, and remove dirt, oil buildup, and other residues.

  • Nioxin hair styling products. These include gels, hairsprays, and mousse formulated to help your hair look thicker and fuller.  

  • 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.

Nioxin also sells products formulated for specific hair types and needs — like shampoos safe for color-treated hair or dandruff–prone scalps.

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

Nioxin products contain various ingredients to promote hair growth. While some are backed by solid research, others lack strong clinical evidence. 

Below, we break down Nioxin’s hair care products, hair styling products, and medications. 

We’ll explore their active ingredients and see what the research says about their effectiveness for hair loss.

Nioxin Hair Care and Hair Loss 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:

Some research suggests that saw palmetto may reduce local dihydrotestosterone (DHT) levels, slowing down hair loss. DHT is a hormone that plays a major role in male pattern baldness. 

However, there’s little evidence to suggest that the other key ingredients directly promote hair growth or slow down hair loss.  

You can also get Nioxin scalp care products, which aim to relieve an itchy scalp. While an irritated or dry scalp doesn’t directly cause hair loss, your scalp health is an important part of your overall hair health. Our blog discusses the connection between itchy scalp and hair loss.

Nioxin’s hair care products might improve the look and feel of your hair, but they’re not a cure for male pattern baldness.

Nioxin Hair Styling Products 

Nioxin also sells several hair styling products specially formulated for people with thinning or fine hair. These products may help your hair look fuller.

Styling products won’t kickstart growth, but they may help your hair look fuller. You’ll get the best results by combining these products with an effective hair loss medication, like minoxidil. 

Nioxin Hair Growth Treatment

Nioxin’s hair regrowth treatment contains the active ingredient minoxidil (AKA Rogaine).

Minoxidil is a highly effective, research-backed treatment for hair loss. Plenty of evidence shows it can stimulate hair growth, especially in people with pattern hair loss.

It’s also quite safe. In fact, it’s one of the few FDA-approved hair loss treatments on the market. 

Minoxidil works by lengthening the anagen phase (growth phase) of the hair growth cycle. This means your hair follicles stay in growth mode for longer, allowing your hair to grow for a longer period of time before falling out. 

It may also work by stimulating blood circulation in the scalp

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

Here are a few benefits of using Nioxin:

  • Some Nioxin products are effective for hair loss. Based on the active ingredients previously mentioned, certain Nioxin hair care products can help stimulate hair growth.

  • There’s a wide variety of products. The brand sells a range of products from hair gel to cleansers and shampoos.

  • The products are simple to use. Products have easy-to-follow instructions.

  • Overall, customer satisfaction seems high. Reviews on the website and third-party sites suggest that the products are good quality. Customers claim Nioxin helps them maintain thick, healthy hair. 

These are the potential drawbacks of using Nioxin: 

  • Not all products are equally effective. Some Nioxin products contain proven ingredients like minoxidil, while others rely on ingredients with weak evidence when it comes to actually reducing hair loss. 

  • The products are expensive. Depending on your hair care routine budget, Nioxin products may put a dent in your wallet. 

  • Once you stop using the products, you can lose new hair. Like with any minoxidil treatment, if you stop using Nioxin minoxidil, your hair may start falling out again in three to four months.

It’s a good idea to weigh the pros and cons of Nioxin before committing to a purchase.

Noticed early signs of hair loss or a receding hairline? Acting fast is key. Hair loss usually gets worse over time, so the sooner you treat it, the better.  

But Nioxin isn’t your only hair loss treatment option. Let’s dig in.

Finasteride

Finasteride (AKA Propecia®) is an FDA-approved treatment for male androgenetic alopecia. 

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

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.

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.

Other DHT-Blocking Shampoos

Many companies (beyond Nioxin) make DHT-blocking shampoos and conditioners.

These products often contain DHT-blocking ingredients like ketoconazole and saw palmetto to slow down hair loss.

Our thickening shampoo contains saw palmetto to block DHT and other ingredients to clear up sebum build up and support a healthy scalp.

If you feel like your hair’s a little flat, try our volumizing shampoo and volumizing conditioner to help your hair look a little more lively.

Hair Growth Supplements

Certain nutrients are essential for hair growth. Some nutrient deficiencies can lead to a form of temporary hair loss called telogen effluvium

You can get most of these nutrients by eating a balanced, healthy diet. But if you struggle to meet your nutritional needs, you might want to try a dietary supplement, like our biotin gummies

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

Does Nioxin work? It might, but it’s far from the only (or the most promising) option. If you have male pattern baldness, it’s better to seek proven hair loss treatments — and get guidance from an expert.

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

  • Nioxin is a brand that offers a line of hair care products. Offerings include shampoos, conditioners, styling products, and hair loss medications.

  • Each product contains different active ingredients. Some of these ingredients seem to support hair growth, while others aren’t as well-researched. 

  • Nioxin isn’t your only treatment option.  Alternatives to Nioxin include finasteride, biotin, DHT-blocking shampoos, and other minoxidil treatments — All available through Hims. 

If you think you’re experiencing hair loss, consider speaking with a medical professional. Hair loss gets worse over time, so treating it ASAP is important.
