Maintaining strong, long, shiny, and healthy hair is one of the most challenging tasks ever. Every time you step out of your house, you expose your hair to countless factors that can harm your hair. Some food can also introduce free radicals into 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 hair products you use to maintain and style your hair can also be harmful!

Luckily, the market is full of formulated products to deal with such issues. The good thing is that many options allow you to shop around and find the best product for the best price. On the flip side, the vast number of products is overwhelming, and worse, not all of the hair care products you come across work. Some of them are not safe to use 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 are one such product line.

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.

6 Nioxin System Kits

Nioxin System 4 Kits - How To Use

All the kits are designed to provide the complete package to cover your entire hair care routine. This professional hair care product helps clean your hair, stop hair loss, nourish your scalp and hair follicles, protect your hair, and promote healthy growth. This is achieved through a three-part treatment that starts with a deep cleansing shampoo, a scalp therapy conditioner, and a leave-in hair & scalp treatment.

Most people enjoy the best results from using the entire kit. However, you can also get excellent results from just one of the products provided you are compensating for the other two in some other way.

Nioxin System 4 Kits All Nioxin System Kits are formulated to achieve the same results, but the formulas differ slightly. 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.

For that reason, Nioxin developed different formulas to address other 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 severe hair thinning and shedding to get full and voluminous hair. However, a few individuals did not have the best experience with this kit. This shows that Nioxin System 4 does not work for everyone. The most crucial bit is ensuring 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 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 remove follicle-clogging fatty acids, sebum, and other residues without making a mess of your colored hair.

The Nioxin System 4 Cleanser Shampoo should be used like any other. 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. You must run clean water through your hair and ensure no shampoo is left on your scalp and hair. This should 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 Leave-in treatment also gives your hair some shine to improve its appearance.

How to Use Nioxin System 4 Scalp and Hair Leave-In Treatment

The Nioxin System 4 Scalp & Hair Treatment offers an easy and mess-free application. Start by shaking the bottle well to redistribute the ingredients. Put a few drops on your scalp, then add more drops to your hair and massage the hair. You may want to part your hair into several sections to make the application easy. The whole process should not take more than 9 pumps.

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

Where to Buy Nioxin System 4

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 encountered complaints about buyers receiving products already opened, so be careful where you order them.

  • Itchiness
