Nioxin System 4 Reviewed: Pro’s & Con’s of this hair product

Maintaining strong, long, shiny, and healthy hair is one of the hardest tasks ever. Every time you step out of your house, you expose your hair to countless factors that can harm your hair. Some of the food you eat can also introduce free radicals in your system, affecting your scalp and hair follicles. Even worse, if your diet is poor, chances are your scalp and hair follicles will be malnourished, and this triggers hair thinning and loss. Some of the hair products you use to maintain and style your hair can also be harmful!

Luckily, the market is full of products that are formulated to deal with such issues. The good thing is that having lots of options gives you the opportunity to shop around and find the best product for the best price. On the flip side, the vast number of products is very overwhelming, and worse, not all of the hair care products you come across work. Some of them are not even safe to be used in the first place. So, how do you know which one works?

Nioxin is not a newcomer in the hair industry. The company has been around for well over 30 years. Formed in 1987 by Eva Graham – who also went through serious hair issues – the company has produced various hair products, some of which have enjoyed enormous success. The Nioxin System Kits is one such product line.


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



The Nioxin System Kits are available in 6 options.

Nioxin System 1-6 How to Use

All the kits are designed to provide the full package you need to cover your entire hair care routine. They help clean your hair, stop hair loss, nourish your scalp and hair follicles, protect your hair, and promote healthy hair growth. This is achieved through a three-part treatment that starts with a deep cleansing shampoo, a scalp therapy conditioner, and a leave-in scalp & hair treatment. Most people enjoy the best results from using the entire kit. However, you can also get amazing results from just one of the products provided you are compensating for the other two in some other way.

Nioxin System Kit 4 Hair for Color Treated Hair, For Women and Men with Progressed & Advanced Thinning Hair, 3 Piece Set, Full Size (Three Month Supply) All Nioxin System Kits are formulated to achieve the same results, but the formulas are slightly different. Here is the thing, people do not have the same type of hair and hair loss problems.

Some people have tough, coarse hair, while others have curly hair. Some have natural hair, while others have chemically treated and colored hair. Also, some people have mild hair thinning, while others are stressed out with progressed hair thinning. Therefore, it makes perfect sense that one formula cannot work for everyone.

It’s for that reason that Nioxin developed different formulas to address different issues. For instance, the Nioxin System 1 is formulated for people with natural hair with mild thinning, while Nioxin System 6 is for people with chemically treated hair with mild-moderate thinning.

Today, we’ll be taking a closer look at Nioxin System 4. The kit is formulated for people with colored hair with progressed thinning. The kit is designed to give you thicker, fuller, and generally healthier hair. It also helps to support scalp health. It maintains the right moisture balance and keeps your scalp and hair feeling fresh.

Based on the user reviews, it’s clear that the kit lives up to the hype. The Nioxin System 4 before and after results shared online show users who’ve recovered from serious hair thinning and shedding to get full and voluminous hair. However, there were a few individuals who did not have the best experience with this kit. This shows that Nioxin System 4 does not work for everyone, but honestly, it’s impossible to find a beauty product does. The most important bit is making sure that your hair meets the requirements for this particular kit and that you use it as recommended.

With that said, here is what you can expect from each of the products present in the kit:

Nioxin System 4 Cleanser Shampoo

Finding the right shampoo for colored hair can be a bit tricky. Some of the shampoos can mess up with your color treatments, while others can leave the color intact but fail to get the cleansing done properly. The Nioxin System 4 cleanser shampoo strikes the perfect balance between both. It will deep cleanse your hair and get rid of follicle-clogging fatty acids, sebum, and other residues without making a mess of your colored hair.

How to Use

The Nioxin System 4 Cleanser Shampoo should be used just like any other shampoo. Start by wetting your hair and then apply some shampoo. Massage it throughout your scalp and hair to form a lather. This should take around 2 minutes.

Finish up by rinsing your hair thoroughly. It’s important that you run clean water through your hair and ensure there is no shampoo left on your scalp and hair. This should actually be standard practice with all shampoo because leaving any traces results in residues that weigh down your hair and affect the overall health of your scalp and hair.

The Nioxin System 4 Cleanser Shampoo should be used daily for the best results.

The Nioxin System 4 Scalp Therapy Conditioner should be used after cleansing your hair. This lightweight conditioner is color-friendly and strengthens the hair to reduce hair breakage and thinning. It also supports the hair structure and a healthy moisture balance.

Nioxin Scalp and Hair Leave-In Treatment System 4

Add some more drops on your hair and massage the hair. You may want to part your hair into several sections to make the application simple. The whole process should not take more than 9 pumps.

Once you are done massaging, you can rinse your hands and go on with your business. It’s a leave-in treatment, so don’t wash it off after application.

Where to Buy

All Nioxin Products, including the System 4 Kit, are available on online stores like Amazon. You can also find it in other beauty stores, including Ultra. I’ll encourage you to stick to the major retailers to avoid buying a fake. I also came across complaints about buyers receiving products that are already opened, so be careful about where you choose to order it.

Nioxin System 4 Reviews

Here are some of the top reviews of Nioxin System 4 users:

“This is the best hair product I have used in 50 years. It keeps my hair from being fizzing, hair loss. Everyone wants to touch my hair, and the minty smell is so relaxing when u put it on. I highly recommend these products. I use 3 and 4″ By Rocky

“I’ve been using this hair care system for about a month now, and I’m already noticing that my hair is much fuller. Not only can I tell, but others can as well. I use the pill supplement in conjunction with this hair treatment hoping for optimum results. I will replenish both the liquid and pill form of these Nioxin products when the need comes. I’m a very happy customer!” By Sarah

“I had high hopes but was disappointed. I have used this product for 3 weeks, and my hair feels fried. I used all three products as described, and it is an almost impossible brush/comb my hair without losing more hair. My hair is healthy, and I really don’t use any products in it. I do have to say it smells good.” By Zman1

Final Verdict

The Nioxin System 4 is an incredible kit for anyone with colored hair with progressed thinning. It helps deal with hair breakage and loss, scalp and hair dryness, and moisture issues without affecting the color of your hair.

With that said, you should stop using the kit right away and consult a physician if you experience any severe side effects.
