Nioxin Research Laboratories Inc.

Nioxin Research Laboratories Inc. was founded back in 1987 by Eva Graham. Since then, the company has undergone several changes to adapt to the changing industry. For instance, they have slightly adjusted some of their hair products to improve the formulas and produce better results.

In 2008, Nioxin Research Laboratories Inc. was acquired by Proctor and Gamble (P&G), who made several changes, including moving the company from Lithia Springs, Georgia, to Mexico. Despite all these changes, the one thing that seems to have remained constant is the effectiveness of their professional hair products.

Nioxin System 6 Kit

What is the Nioxin System 6 Kit?

There are six different Nioxin System Kits. The Nioxin hair care system is formulated to help fight hair thinning and improve hair thickness and overall growth. However, each has a unique formula that allows only a specific group of people to use them.

For instance, the Nioxin System 1 is specially formulated for people with natural hair with slight thinning. On the other hand, the Nioxin System 6 is designed for chemically treated or bleached hair that’s either medium or coarse and with noticeable or progressed thinning.


nioxin system 6 number

The Nioxin 6, like the other kits, comes in three parts; a cleanser or shampoo, a scalp therapy conditioner, and a scalp and hair leave-in treatment. Nioxin encourages people to buy and use the kit for the best results.

Nioxin System 6 Shampoo

Nioxin System 6 Scalp Cleansing Shampoo with Peppermint Oil, Treats Dry Scalp, Dandruff Relief, Anti-Hair Breakage, For Bleached & Chemically Treated Hair with Progressed Thinning, 33.8 fl oz

The Nioxin System 6 kit starts with a cleansing shampoo. The Nioxin Cleanser Shampoo is formulated to deep cleanse your scalp and hair. You may not know this, but most of the hair products we use to leave behind residues that can accumulate in the scalp and hair. We also expose our hair to pollutants like smoke and dust, which can settle in the hair. Over time, these pollutants and residues pile up and affect the health of your hair. They can even stimulate thinning and shedding of hair.

The Nioxin System 6 shampoo contains the right ingredients to exfoliate the dirt, sebum, and residues lurking in your scalp and air. It helps to unclog the pores, allowing the hair follicles to flourish. In the end, this shampoo leaves your hair squeaky clean. A clean scalp and hair provide the perfect atmosphere for healthy hair growth.

Besides cleansing your scalp and hair, the Nioxin 6 Shampoo also provides essential nutrients that nourish your scalp and hair follicles. That’s why the cleanser stands out in the market because it does more than what a standard shampoo is capable of.

Nioxin Scalp Treatment 6 Reviews

I’ve used it 9 years. It took 3 months for noticeable change. I had significant regrowth for the first year. Every year after the regrowth has slowed down. After 5 years, I feel like the regrowth is very minimal or hard to measure.

I use this foam along with Nioxin 4 shampoo and conditioner. Since I’ve started using it, I’m finally seeing new growth. Whatever it is, I’m not stopping any of it! I’m a beautiful woman and I refuse to go bald without a fight!

I have only been using this for a few weeks, and have already noticed a difference, less hair loss and the hair seems thicker, i will definitely continue to use the product i think does make a difference

It’s vital to go through the label and find any ingredient you might be allergic to before using it. On that note, Nioxin Systems include some sulfates in the formula, so you may want to use them carefully if you do not react well to the ingredient.

Nioxin System 6 Reviews

Here are some of the top positive and negative user reviews of Nioxin System 6:

“My hairdresser suggested this when my hair started falling out in handfuls. I was skeptical but desperate. In just a month, I had tiny baby hairs sticking up all over. -the regrowth has been amazing. I can’t say enough good things about this. Highly recommend.” By Sunonthebeach

“The hair product is excellent. It is a shame that the bottle are so small. Good for one person, but too small for two people for one month. I wish that they would put together a package with much bigger bottle sizes like they do with the System #4 Product. The System #6 is for more serious problems with balding, etc. We need the same size bottles as the #4 system!” By Andy W

“I did not like the results of using this product. My hair was left frizzy and unmanageable. I threw most of it away.” By Susan

FAQs about Nioxin Kit System 6

How Fast Does Nioxin System 6 Work?

The Nioxin System 6 is a powerful kit but not a miraculous one. It requires some time to produce the desired results. According to the manufacturer, the system requires 6 months to have full effects. However, the first few changes should appear within a month of regular use. For instance, most users report a decrease in hair thinning after around 4 weeks. Some say an increase in hair thickness and volume after 6-7 weeks.

It’s important to remember that some people may see results sooner than others. This happens with all hair products. Practice patience and give the kit time to work on your hair. The bottom line is you should see some changes within 2 months of regular use.

Can You Continue Treating Your Hair?

Yes, you can. The Nioxin System 6 supports bleached and chemically-treated hair, so you don’t have to stop treating your hair while using the kit. However, it’s best to stick to healthy natural treatments.

Where is Nioxin made?

Nioxin isn’t a chemical; it’s a brand of hair care products specially made for alopecia sufferers or hair loss. Its founder, Eva Graham, began experimenting with different herbs and flowers at home, believing that gentle ingredients yielded the best results. Today, Nioxin specializes in products that offer a wide range of hair care effects. 

Nioxin Systems 4 vs. 6: What’s the Difference?

Nioxin System 6 is made for chemically treated or bleached hair. Nioxin System 4, on the other hand, is specially made for color-treated hair. Finding the Nioxin System that will suit your hair is important, as they’re tailor-made to fit specific niches.

Nioxin Systems 5 vs. 6: What’s the Difference?

Nioxin Systems 5 and 6 are made to fight hair loss on chemically treated or bleached scalps. Where they differ is the user’s level of hair loss. For those with average to light thinning, Nioxin recommends using System 5. For progressed thinning, System 6 is a better choice. System 6 has a more robust formulation than System 5, offering UV protection for sensitive hair. 

Which is the best Nioxin for Chemically Treated Hair?

Nioxin offers several packages called Nioxin Systems. Each of these is carefully made to treat specific kinds of hair loss. For chemically treated hair, your best option is either Nioxin System 5 or 6. These are made for different degrees of hair loss and work just as well on bleached hair. It also provides a powerful moisturizing effect to stop alopecia from doing more damage.

Is Nioxin Sulfate and Paraben Free?

Unfortunately, not all Nioxin products are free from sulfates and parabens. However, Nioxin has taken the time to create the most gentle yet effective blend possible. It’s advised to check the Nioxin system you intend to buy before committing to it, especially if your scalp is sensitive to these chemicals.

If You Stop Using Nioxin, Will Your Hair Fall Out?

There have been no findings that directly link discontinued Nioxin use with hair loss. Most people report mild shedding after stopping their Nioxin use. Any more than mild shedding may indicate an allergic reaction.

Final Verdict

Nioxin System 6 is an excellent option for people with bleached or chemically treated hair with progressed thinning. It’s a complete kit that cleanses your hair, helps stop hair loss, promotes the growth of strong, thick, and healthy hair, and protects your hair against harsh surroundings. It usually takes 6 months to see the full results, but you should start seeing changes within 4 weeks of regular use.

Nioxin level 6 is generally safe, but you should stop using it if you experience severe side effects like swelling and hives. Also, do not use it if your hair does not meet the specific criteria that System 6 requires because it will not work.

Try the Catalese Shampoo if you’re having issues like hair greying, or pick good biotin shampoos that stimulate strong and thick hair growth.
