All About Nioxin

Nioxin is a hair care brand that has been helping people with thinning hair for over 30 years. In fact, Lauren Pope, a British reality television star, is a big fan of Nioxin. She frequently uses the Nioxin System 2 pomade to keep her own hair looking thick and healthy.

The Nioxin Research Laboratories was started by Eva Graham in 1987. Since then, they’ve produced numerous product lines that addressed different hair concerns and needs and the Nioxin System kits are one such product line.

What Nioxin System Should I Use?

There are six different Nioxin System Kits available on the market today. Each aims to help stop hair loss, promote hair growth, and protect your hair.

However, their formulas have key distinctions. These key features help you determine which product should be used. For instance, the Nioxin System 1 is best for people with natural hair with little thinning.

That’s why System 1 doesn’t work for people with chemically treated or colored hair. It also means that anyone with aggressive thinning cannot get the ideal results from System 1.

Nioxin System 2 Review

Nioxin System Kit 2, Natural Hair with Light Thinning, Full Size (3 Month Supply)

The Nioxin System 2 is almost similar to System 1 but for a few differences. The System 2 is formulated for individuals with progressed hair thinning.

It’s not the best for aggressive thinning, but it’s definitely a good choice for hair that’s going through more than average thinning.

Other than that, its ingredients and features are similar to the Nioxin System 1. For instance, System 2 suits people with natural and non-colored hair.

What does progressed thinning mean?

Progressed thinning is somewhere between thinning hair and balding edges or patches. The Nioxin Systems 2, 4, and 6 are most suitable for people with progressed thinning hair.

How Does the Nioxin System 2 Work?

You can think of the Nioxin System Kits as the complete package. They help you to stop hair thinning and shedding. They solve scalp issues such as dryness, itchiness, and dandruff. They help create a healthy atmosphere for your scalp and the hair follicles to grow strong, full, and generally healthy hair.

They provide antioxidant protection that reverses the damage your hair has already suffered. It also protects your hair and scalp from the free radicals you are bound to encounter daily.

The important part is ensuring that you are using the right kit. And if you have progressed thinning of natural hair, the System 2 is the best kit for you.

Nioxin System 2 Review: Active Ingredients

It’s important to check the label of every hair product before using it. These products contain harsh chemicals that can cause scalp irritation, itchiness, and other adverse reactions. Also, check for any compounds you could be sensitive to or allergic to.

The products in Nioxin System 2 contain a lot of compounds. I’m only going to highlight and discuss some of them. But I’ll make sure to include a full ingredient list for each product. So make sure to read the whole list before using it.

Biotin, Vitamin B Complex (Grapefruit, Yeast Polypeptides)

What I love about the Nioxin System 2 kit is that it contains a range of Vitamin Bs, including Biotin, Folic Acid, Cyanocobalamin, Niacinamide, Pantothenic Acid, Pyridoxine, Riboflavin, and Thiamine).

As one of the reasons for hair loss is vitamin deficiency, Vitamin B helps with hair loss by supplying your hair follicles with red blood cells that carry these hair-building nutrients. It also stimulates blood flow on the scalp, promoting growth on balding/thinning patches.

Serenoa Serrulata (Saw Palmetto) 

Saw Palmetto is one of the leading natural ingredients in the hair loss industry nowadays. Because of its anti-DHT benefits, you can see it incorporated in many hair growth supplements and shampoos. It functions just like Minoxidil in preventing the formation of hair loss, promoting DHT, and stimulating the growth of new hair strands.

Camellia Sinensis Tea Leaf Extract

Tea tree and tea leaf extracts also function just like Minoxidil and Saw Palmetto in promoting blood flow and preventing DHT build-up on the scalp. It also contains antioxidants that further protect hair from damage and nourish it from the outside.

Salicylic Acid

I found that the Nioxin System 2 also contains salicylic acid. Salicylic acid can help remove product build-up and kill fungus on the scalp, which can also promote hair loss. It also has anti-inflammatory properties that stop itching and prevents you from scratching and further damaging your scalp.

Nioxin System 2 Kit Products

All the Nioxin System Kits come in three parts. You will get a cleanser or shampoo, a scalp therapy conditioner, and a scalp and hair treatment.

These products are usually sold together in a single kit, but you can also get them separately. You are highly encouraged to use the whole kit to experience the best results.

Nioxin System 2 Shampoo


Nioxin System 2 Cleanser Shampoo, Natural Hair with Progressed Thinning, 33.8 Fl Oz

The Nioxin System 2 starts with a cleanser. This shampoo aims to deliver deep cleansing. It exfoliates residues lurking on your scalp and between your hair.

Remember that some hair products you use for styling and general hair care tend to leave many residues behind. Your hair is also exposed to pollutants every time you step outside.

These residues can accumulate on your scalp and block your pores. They affect the health of your scalp and hair follicles. If left unresolved, the residues can stop hair growth and even cause hair thinning.

Cleansing is the primary focus of this Nioxin Hair Thinning shampoo, but it is not the only one. This Nioxin System 2 shampoo also contains ingredients like Peppermint and Saw Palmetto that stimulate hair growth.

In addition to that, it contains Vitamin Bs that help nourish the scalp and encourage stronger hair growth.

One thing worth noting is that this shampoo contains alcohol and sulfates. So, if you’re allergic to these ingredients, I highly suggest that you get sulfate-free anti-hair loss shampoos like Dr. Hempster.

Nioxin System 2 Cleanser Ingredient:

This shampoo contains Biotin/Folic Acid/Cyanocobalamin/Niacinamide/Pantothenic Acid/Pyridoxine/Riboflavin/Thiamine/Yeast Polypeptides, Camellia Sinensis Leaf Extract, Citric Acid, Citrus Paradisi (Grapefruit) Peel Extract, Cocamidopropyl Betaine, Cystine Bis-PG/Propyl Silanetriol, Humulus Lupulus (Hops) Extract, Lecithin, Mentha Arvensis Leaf Oil, Mentha Piperita (Peppermint) Oil, Menthol, Propylene Glycol, Red 33, Saccharomyces/Copper Ferment, Saccharomyces/Iron Ferment, Saccharomyces/Magnesium Ferment, Saccharomyces/Silicon Ferment, Saccharomyces/Zinc Ferment, Salicylic Acid, Serenoa Serrulata Fruit Extract, Sodium Benzoate, Sodium Chloride, Sodium Citrate, Sodium Laureth Sulfate, Sodium Lauryl Sulfate.

Nioxin System 2 Conditioner

Nioxin System 2 Scalp Therapy Conditioner, Natural Hair with Progressed Thinning, 33.8 oz

Following the shampoo is the Nioxin System 2 Scalp Therapy Conditioner. It is not like any other conditioner.

It contains the same ingredients as the Nioxin System 2 shampoo, including Vitamin Bs, Tea Tree extract, Saw Palmetto, and Grapefruit extract. This is an outstanding formula perfect for nourishing your scalp and natural hair. 

Just like the Nioxin System 2 shampoo, this conditioner, though, is not all-natural and may contain some dimethicones and alcohol. Dimethicones are what give conditioner its smooth, slippery texture. They coat your hair, so it feels softer and looks shinier.

If used regularly, dimethicones can build up on your hair and scalp, resulting in greasiness and, for some, hair loss.

To avoid this, ensure that you avoid applying conditioner to your scalp. Instead, focus on the mid-lengths and ends of your hair and rinse your hair thoroughly after application.

Nioxin System 2 Scalp Therapy Conditioner Ingredients:

Water, Cetyl Alcohol, Stearamidopropyl Dimethylamine, Stearyl Alcohol, Quaternium-18, Benzyl Alcohol, Cetearyl Alcohol, Hydroxypropyl Guar, Glyceryl Stearate, Oleyl Alcohol, Hydroxyethylcellulose, Mentha Piperita (Peppermint) Oil, Mentha Arvensis Leaf Oil, Menthol, Citric Acid, Polysorbate 60, Bis-Aminopropyl Dimethicone, EDTA, Propylene Glycol, Methylisothiazolinone, Camellia Sinensis Leaf Extract, Cystine Bis-PG-Propyl Silanetriol, Lecithin, Humulus Lupulus (Hops) Extract, Serenoa Serrulata Fruit Extract, Citrus Paradisi (Grapefruit) Peel Extract, Urtica Dioica (Nettle) Extract, Saccharomyces/Magnesium Ferment, Biotin/Folic Acid/Cyanocobalamin/Niacinamide/Pantothenic Acid/Pyridoxine/Riboflavin/Thiamine/Yeast Polypeptides, Yeast Extract, Saccharomyces/Iron Ferment, Saccharomyces/Copper Ferment, Saccharomyces/Silicon Ferment, Saccharomyces/Zinc Ferment, Phenoxyethanol, Blue 1.

Nioxin System 2 Scalp Treatment

Nioxin System Scalp & Hair Treatment, Natural Hair with Progressed Thinning, 3.38 fl oz

Finally, you finish your treatment with the Nioxin System 2 Scalp & Hair Treatment.

This leave-in treatment refreshes your scalp with its menthol and peppermint ingredients. It also nourishes your hair follicles with its Vitamin B content. The Saw Palmetto and Tea Tree oil content help stimulate blood flow leading to new hair growth.

What I love about this treatment is that it doesn’t contain any ingredients that may irritate your scalp. That’s why it is safe to leave on the hair and scalp the whole day. It also contains sunscreen ingredients (Ensulizole, Benzophenone-4) that keep hair and scalp protected from free radicals.

How to Use Nioxin System 2

Shampoo and Conditioner

Your treatment should start with the cleanser, followed by the conditioner, and conclude with the scalp & hair treatment. Apply the cleanser on wet hair and massage it gently. Make sure every part of your scalp and hair is covered. Continue to lather it for a minute and then wash it off thoroughly.

Apply the Nioxin System 2 conditioner after cleansing your scalp and hair. Massage it throughout your scalp and hair. Let it sit for 1-3 minutes, then rinse it thoroughly.

How to Apply Nioxin Scalp and Hair Treatment?

Shake the bottle of Nioxin Scalp and Hair Treatment well before each use. Proceed to apply up to 9 drops on damp hair. Try and apply some of the drops directly to the scalp. Now, massage the scalp, followed by the hair. Leave it on and do not rinse after application.

Where to Buy Nioxin System 2 

Nioxin System 2 is available in various online stores, including Amazon. You can buy the entire kit or buy the products separately.

[amazon box=”B078YGKR6S” description_items=”2″ description_length=”50″ title_length=”50″/]

How Fast Does It Work?

The manufacturer recommends the regular use of Nioxin System 2 for six months to experience the full results. However, you should start seeing results after around four weeks. Hair shedding and thinning should reduce by this point. Most people experience an increase in hair growth and volume after six weeks.

Results usually vary from user to user, but you should be able to tell whether the Nioxin System 2 is working after around eight weeks.

Nioxin System 2 Side Effects

Most people use Nioxin System 2 without experiencing any complications. On the flip side, some users report itchiness, irritation, scalp redness, and swelling. Stop using the product if these issues persist.

Nioxin System 2 Reviews

After reading customer feedback, here is a summary of the Nioxin System2 Reviews:

  • Nioxin System 2 works, but it takes time to see results.
  • Many people stopped using the kit before they saw results because they got impatient.
  • The shampoo and conditioner have a strong chemical smell, but they work well.
  • Some people have sensitive scalps and cannot use this product.

Nioxin Complaints

The only Nioxin complaint we have found in the review sections is the fact that the products in the kit still contain ingredients like alcohol, sulfate, and dimethicones that can cause irritation and allergies if you have sensitive scalps.

Make sure to read the label and ingredients and see if you’re allergic to any. Allergies can cause itching or further damage to your scalp resulting in more hair loss.

FAQs about Nioxin System 2

Nioxin System 1 vs. 2? What’s the difference?

The Nioxin System 1 Kit is for people with light thinning and lightly dry natural (not colored) hair. On the other hand, the Nioxin System 2 Kit is for people with uncolored hair but with noticeably thinning.

I suggest that you use the correct kit as the System 2 kit may be harsh for people with lightly thinning hair, or the System 1 kit may not be that effective for people with more progressed hair thinning.

Is Nioxin 2 safe for color-treated hair?

The Nioxin System 2 Kit is not suitable for people with color-treated hair. The correct product for you is either the Nioxin System 3 or the Nioxin 4 Kit.

Does Nioxin cause hair loss?

Based on customer reviews, Nioxin has helped stop hair loss for most. There are no reviews/comments on their Amazon product page about people losing hair after using this product. The only worst thing you may encounter is the product not working after several months.

How many times a week should I use Nioxin?

The Nioxin System 2 Kit is safe for daily use. For maximum results, use it according to the manufacturer’s instructions.

Is Nioxin scalp recovery color safe?

I see no ingredients in the System 2 Kit that can erode/remove colored hair or even natural hair. But remember that the Nioxin System 2 kit is not recommended for people with colored hair. Get the Nioxin System 3 or 4 kit instead if you have color-treated hair, as it has ingredients that can also help deal with damaged hair.

How long does Nioxin take to see results?

The majority of customers see positive results as early as 30 days.

Is Nioxin shampoo good for thinning hair?

Yes, the Nioxin shampoo, conditioner, and scalp treatment are dedicated products for hair loss. However, users not experiencing hair loss can also use them as a preventive measure.

What happens when you stop using Nioxin?

If you haven’t addressed the major reasons for your hair loss, like stress and deficiencies, your hair can continue to fall if you stop using Nioxin.

When to use Nioxin scalp treatment?

The Nioxin scalp treatment is recommended to be used daily after using the Nioxin Shampoo and conditioner.

Is Nioxin good for African-American hair?

The Nioxin products are suitable for all hair and scalp types. I suggest that you use the correct system for your hair needs. For African American users with natural hair, use the System 1 or System 2 Kit.

Is Nioxin good for dandruff?

The Nioxin shampoo contains salicylic acid, an active ingredient that can kill fungus and remove flakes on the scalp. That’s why if you have dandruff, Nioxin can also help remove this build-up.

Final Verdict of our Nioxin System 2 Review

Overall, the Nioxin System 2 hair growth kit is a pretty good deal. For the price, you get a decently sized bottle of shampoo and conditioner that contains Vitamin B and natural anti-DHT ingredients for hair loss. It’s also highly rated, so you know you’re getting a quality product.

However, there are a few downsides. First, it’s not all natural – it contains sulfates, alcohol, and dimethicones. Second, unlike other hair growth brands, Nioxin doesn’t offer vitamins or supplements that I believe can help maximize hair growth, as well.

Overall, though, considering its price and ingredients, the Nioxin System 2 hair growth kit is a great choice for patient customers looking for an affordable hair growth solution.

Be sure to use it as recommended and if you experience any reactions like irritation and itchiness, stop using it and consult your doctor.
