Who is Nioxin?

Nioxin is a famous brand in the haircare industry. Founder Eva Graham started the company more than 30 years ago after failing to find a solution to her terrible post-natal hair loss. Her experience inspired her to come up with her own unique products. 

After years of hard work, Nioxin was born. Finally, she made products that address the need to resolve hair loss and stimulate hair growth.

If you’re looking for a more potent solution for hair thinning and shedding, you might want to try the revolutionary product Folexin. Folexin is a professional formula that nourishes your hair and supports its natural growth process.

What are the different Nioxin System Hair Kits?

Nioxin created six system hair kits based on two essential factors: color hair treatment and intensity of hair loss. For example, Nioxin System 1 is for people with no hair color and experience light-thinning. Likewise, the Nioxin System 2 is also for people with no hair color but who experience progressed thinning.

Nioxin System 1 Overview

Nioxin System 1

As I said earlier, the Nioxin System 1 is formulated for people with natural or uncolored hair who experiences light-thinning. More precisely, it is for people who notice hair fall but who don’t have exposed scalp areas. If you have scalp patches, bald spots, and your hair is in terrible condition, this Nioxin System 1 is not for you. 

Like the other Nioxin hair kits, Nioxin System 1 comes as a three-product package. It includes the following:

  • Nioxin System 1 Cleanser (Shampoo)
  • Nioxin System 1 Conditioner (Scalp revitalizer) 
  • Scalp and Hair Treatment

How Does Nioxin System 1 Work?

The Nioxin System 1 comes as a complete package where each product fulfills its purpose, but they all work to complement each other and give you the best possible results. 

The System is designed to do the following:

First, clean and detoxify the scalp and hair, and remove residues and impurities that clog nutrient pathways that often lead to poor hair growth. 

Second, moisturize the scalp and hair to make hair roots more resilient and strengthen new hair growth. 

Third, to nourish the scalp and hair with ingredients rich in vitamins, minerals, and antioxidants to protect hair from breakage that often lead to hair fall. 

Nioxin System 1 Active Ingredients

The Nioxin System 1 products contain a combination of vitamins, minerals, plant extracts, and chemicals that have cleansing, moisturizing, pH-balancing, anti-hair fall, and hair-growing properties.

In this section, I will only discuss some of the active ingredients found in all three products. Please check each item’s complete list of ingredients to ensure that you are not susceptible or allergic to any before using them.

Biotin, B-Vitamins

One of the things that I love about the Nioxin System 1 is that it contains B-Vitamins like Biotin, Niacinamide, and Panthenol. 

Biotin deficiency is one of the many factors that cause hair loss. On the other hand, Niacinamide stimulates circulation that helps deliver oxygen and nutrients to hair follicles. At the same time, Panthenol is derived from pantothenic acid or Vitamin B-5. It draws and seals moisture on hair strands. 

Peppermint Oil 

Peppermint oil is an age old remedy for scalp problems like itching, flaking, and irritation. Aside from its soothing, antimicrobial, and anti-inflammatory properties, some studies suggest it also helps increase hair growth. 

Hops extract

Hops extract comes from hops, a female perennial vine. This ingredient is packed with antioxidants. It also has antibacterial and anti-inflammatory properties that help fight itching and dandruff. Hops extract also prevents hair fall and promotes hair growth by inhibiting the activity of 5a-reductase.

Nettle extract

Nettle extract contains Vitamins A, B, C, D, and E. It is also packed with minerals like folate and silica, which promotes stronger hair growth. This ingredient also blocks dihydrotestosterone (DHT), a male hormone that causes alopecia or hair loss. 

White Tea Extract

White tea extract promotes blood flow and prevents DHT buildup on the scalp. It also contains antioxidants that further protect hair from damage and nourish it from the outside.

Salicylic acid 

Salicylic acid removes dead skin, eliminates oil buildup, helps treat dandruff, and soothes irritation. 

Citric acid

Citric acid lowers the pH level of the hair, making it smooth and less frizzy. 


Nioxin System 1 Products

The Nioxin System 1 contains shampoo, conditioner, and leave-in scalp and hair treatment. You can use these items separately. However, you must use the entire kit to get the full benefits of this hair kit 

Nioxin System 1 Cleanser

Nioxin System 1 Cleanser Shampoo, Natural Hair with Light Thinning, 33.8 Fl oz (Pack of 1)

The Nioxin System 1 Cleanser is the first product in the 3-step routine. It is a daily detoxifying scalp and hair shampoo. 

This hair cleanser uses deep cleansing agents like Sulfates, Cocamidopropyl Betaine, Sodium Xylenesulfonate, and Cocamide MEA to remove toxins, product buildup, mineral residues, and other pollutants that accumulate on the scalp and hair overtime.

Removing impurities is the first step in preventing hair fall and promoting growth. When the scalp is thoroughly clean, nutrients flow smoothly, making hair grow stronger. At the same time, clean hair strands are lighter, healthier, shiner, and less prone to breakage, which often leads to hair fall. 

Aside from deep cleansing, this Shampoo also contains hair-growing ingredients like Peppermint oil, White tea extract, Bilberry leaf extract, and Orange peel extract.  

As I said earlier, this cleanser has sulfates, alcohol, and other chemical compounds. If you have a sensitive scalp and skin, these ingredients may irritate you.

Nioxin System 1 Conditioner

Nioxin System 1 Scalp Therapy Conditioner, Natural Hair with Light Thinning, 33.8 oz

The Nioxin System 1 Conditioners is the second product in the 3-step routine. It is an after-shampoo product formulated to keep and balance the scalp and hair moisture.

This Conditioner contains Stearamidopropyl Dimethylamine, an ingredient that smoothes hair cuticles, reduces frizziness, tames flyaways, prevents breakage, and less prone to tangling. 

It also has sugarcane, a humectant that draws and seals hair moisture, making hair more resistant to drying and damage, contributing to hair fall. 

One ingredient to watch out for is dimethicones. Over time, this ingredient can build up on your hair and scalp, making them greasy and, for some, causing hair loss. To prevent this from happening, avoid applying this Conditioner on the scalp. Start a few inches from your roots, going down the ends.

Nioxin System 1 Scalp & Hair Leave-In Treatment

Nioxin System 1 Scalp & Hair Treatment, Natural Hair with Light Thinning, 6.8 Fl Oz (Pack of 1)

The Nioxin System 1 Scalp & Hair Treatment is the final product in the 3-step routine. It is a leave-in hair conditioner formulated to increase hair thickness and volume.

What I love about this leave-in treatment is it keeps your scalp and hair nourished in between washings, creating an ideal scalp environment for your hair follicles to grow.

Among the three products in this hair kit, this has the safest and gentlest ingredients. It also contains Ensulizole and Benzophenone-4. These protects the scalp and hair follicles against oxidative stress caused by pollutants and other free radicals.

How to Use Nioxin System 1?

As I pointed out earlier, you can use each of the three products found in the System 1 kit independently (you can buy them separately as well), but the results will not be as impressive. You must use the whole System to get the best possible results. Here is how:

How to Use Nioxin System 1

Nioxin System 1 Cleanser 

Apply the Shampoo on wet hair. Massage it gently but thoroughly to ensure every part of the scalp, and your hair is covered. Lather the Shampoo for a minute or so then rinse thoroughly. It would help if you used Shampoo every day.

Nioxin System 1 Scalp Therapy Conditioner 

Use the Conditioner after rinsing off the Shampoo. Apply the Conditioner and massage it throughout your scalp and hair. Let the Conditioner sit for up to 3 minutes. Rinse it properly. It would help if you used Conditioner every day.

Nioxin System 1 Scalp and Hair Leave-In Treatment 

Start by shaking the bottle. Part your damp hair into 2-3 sections to expose the scalp. Apply up to 9 pumps of the oil evenly. Gently massage the treatment throughout your scalp and the roots of your hair coming towards the ends. Do not rinse your hair after applying the treatment. Please leave it in there to work its magic. It would help if you used Scalp & Hair Treatment every day.

Where to Buy?

Nioxin System 1 is available on Amazon and a few other online stores. You can buy the whole System or each product separately. Of course, you will get a better deal purchasing the entire System.

Nioxin System 1 Side Effects

No adverse side effects are directly associated with the Nioxin System 1 Hair Kit. However, I highly advise that you check the complete list of ingredients to ensure that you are not allergic or susceptible to any of them. Also, remember that these products contain ingredients that can cause irritation, especially for sensitive scalp and skin.

Nioxin System 1 Reviews

Nioxin products are top-rated for a reason. The majority of its users are satisfied with the results of consistently using the System 1 Hair Kit. They love how the Cleanser, Conditioner, and Scalp & Hair Treatment helped with their light hair-thinning and how the products leave their hair feeling clean, fresh, smooth, healthy, and shiny.

That said, it is essential to remember that not because it works for many, it is automatically suitable for all. Some users complain about the strong smell of the products. Others did not see any visible results whatsoever after months of continuous use.

Nioxin System 1 FAQs

How Fast Does Nioxin System 1 Work?

The manufacturer recommends that you use Nioxin for 6 months to get the best results. However, you should start to see minor changes before then. For instance, hair shedding should slow down in the first month or so. Most users report visible changes from the second month of regular use.

Bear in mind that the duration varies from one individual to the next. Some may see results a lot sooner, while others will have to wait a little longer.

Is Nioxin System 1 Safe?

Nioxin System 1 is fairly safe, but it is not 100% free of side effects. A few individuals have reported irritation, tingling, and redness. Stop using it and get in touch with your physician if the side effects persist.

Final Verdict

Nioxin System 1 is an excellent option for people experiencing light hair-thinning. However, it may not be the best, especially for those with sensitive scalp, skin, and hair, as the formulas contain known irritants. 

But if you are not susceptible to sulfates and parabens, it can do well for you. The products included in this kit work to clean, protect, moisturize, and nourish your scalp and hair. After all, the System has helped many women and men get stronger, longer, and thicker hair.

Note that the Nioxin System 1 is ideal for light natural and non-colored hair-thinning individuals. Check out some of the other Nioxin Systems if you are experiencing an increase in hair thinning.
