Nioxin System 4 Review: Real Hair Loss Prevention or Bottled Snake Oil?

Are you frightened to brush your hair because of all the hair that falls out?

Do you despair every morning when you see your pillow covered with the hair you shed?

Hair loss can be frightening and depressing.

It affects our self-esteem and hurts the way we view ourselves. Bald spots and thin hair can be frustrating to deal with and makes many people feel hopeless.

The good news is that hair loss isn’t final or irreversible. There are lots of products that slow down, reduce, or even prevent hair loss. For instance, Rogaine is extremely popular because it reverses the effects of male pattern baldness.

I am going to look into the Nioxin System 4 Hair Care Kit, which is supposed to treat and reduce hair loss. In this Nioxin System 4 review, we are going to look at what is included in the kit, how Nioxin works, and what I like about the products.

So without further ado, let’s get started!    

What’s in the Nioxin System 4 Kit?

The Nioxin Hair System 4 kit has three products. This means it provides all the care your scalp and hair needs. Each product is specially formulated to treat and reduce hair fall.

They strengthen the hair shaft, thus preventing breakage and hair fall. The products also refresh the scalp and keep it healthy. Most importantly, the kit is geared towards people with color-treated hair, so if you have hair loss and dyed hair, these products are meant for you!

Here’s what the kit contains:

Nioxin 4 Cleansing Shampoo:

The Nioxin 4 shampoo is a scalp cleanser for people with color-treated, progressed thinning hair. It aims to remove sebum, grease, fatty acids, and dirt/environmental residue from your scalp. At the same time, it uses Pro-Color Shield technology to protect your dyed hair.

Nioxin Shampoo System 4 reviews show that it does do what it claims. It has a derma-purifying formula that deep cleans the scalp, removing build-up, and leaving you with fuller, healthier, and thicker-looking hair.

Nioxin 4 Scalp Therapy Conditioner:

As any Nioxin System 4 scalp treatment review will tell you, this conditioner is nothing short of miraculous. It acts as a moisturizer for the scalp and this makes your roots look thicker and fuller.

The Bio-Amp technology helps your hair retain moisture. This makes your hair more resilient against breakage and split ends. It amplifies hair structure, but is lightweight and won’t weigh your hair down.

My favorite thing about this conditioner? It contains peppermint oil which gives it a minty smell. It also stimulates your scalp for hair growth, and you can actually feel it since it makes your scalp tingle pleasantly.

Nioxin 4 Scalp and Hair Treatment:

This is a leave-in treatment that refreshes your scalp and adds volume to your hair. It makes use of Scalp Access Delivery System 2.0 technology which increases the diameter of your hair, making it look thicker. It also keeps your scalp healthy, thereby preventing breaking and hair loss.

If you happen to check out a Nioxin System 4 Kit review, you’ll notice that the scalp conditioner and treatment are both quite effective at managing hair loss. As of date, they get rave reviews from customers across the world.

How Does the Nioxin 4 Kit Work?

Nioxin products aim to reduce hair fall by promoting scalp health. They do this in 3 main ways:

Increasing Scalp Circulation:

Our hair follicles need oxygen and nutrients. These are supplied by a network of blood vessels in the scalp. However, certain conditions can cut off this supply of nutrients and oxygen, resulting in poor scalp health and hair fall.

An androgen called DHT connects to the receptors on the follicles and inflames them. When left untreated, this leads to something called hair follicle miniaturization, which in turn results in baldness.

Miniaturization cuts off the supply of oxygen to the follicles. However, Nioxin contains sodium citrate which improves blood flow. As a result, the circulation in the scalp is improved and reverses the process of miniaturization, reducing hair loss.

Reducing scalp DHT Levels:

The androgen DHT also harms the health of the hair follicle and is known to cause irreversible balding. It also stimulates the scalp to over-produce sebum. When sebum accumulates on the scalp, it weakens the hair roots, causing them to fall out.

However, certain ingredients in Nioxin, such as saw palmetto and stinging nettles, reduce DHT levels in the body. This, in turn, reduces hair fall.

Removing Scalp Build-Up:

The Nioxin shampoo cleanses the scalp, removing the build-up of sebum on it. The menthol in the shampoo also soothes the inflammation or irritation of the scalp, making your scalp feel clean and healthy.

Why I Like the Nioxin System 4

 Nioxin System 4 review

In this part of my Nioxin Hair System Kit 4 review, I’m going to go into the aspects of the kit I found useful and significant.

Cleans Hair and Scalp:

The Nioxin 4 Cleansing Shampoo is an excellent cleanser. It lathers well and leaves your hair and scalp feeling squeaky clean. Moreover, it was a great build-up buster; it cleaned greasy day 4 hair without any issue.

Fortifies Roots:

Although I was skeptical, I found that the Nioxin Thinning Hair System 4 reviews were right. The shampoo, conditioner, and treatment all work effectively to strengthen the roots and follicles.

After weeks of use, you will notice that your hair is more resilient and resistant to fallout. Less hair will be shed while washing and combing it.

Improves Scalp Health:

Most of the hair fall issues are caused by poor scalp health. These Nioxin products work to improve scalp health and improve circulation to treat and prevent hair loss. The menthol and peppermint extracts gives the scalp a tingle and makes you feel like the products are doing their work!

Overall Effectiveness:

This kit was definitely effective. And the Nioxin reviews on System 4 online are proof of that. Customers everywhere claim that they can see a visible difference in four to six weeks. With continued, long term use, your hair will regain the thickness and fullness it lost.

Why I Recommend the Nioxin System 4 Kit:

This kit is a lifesaver if you’re dealing with the effects of hair loss. It reduces and slows down hair fall while strengthening your hair and keeping your scalp clean and healthy.

How to Use the Nioxin System 4 Kit

Here’s a little 101 guide on how to use all the products in this kit

  • Wet your hair and scalp thoroughly and apply a dime-sized amount of shampoo. Massage the shampoo into your hair well, working the lather into your roots.
  • Rinse thoroughly with lukewarm water.
  • Apply the conditioner from your scalp to the ends. Leave it on for a couple of minutes and rinse well.
  • Finally, apply the scalp and hair treatment. Shake out your hair and apply the treatment to your scalp, smoothing whatever remaining on your hands to the rest of your hair.
  • Do not rinse and let your hair dry. Avoid using a blow dryer or roughly towel-drying your hair. Air drying will be more gentle and will result in the least amount of hair shed.

Final Thoughts:

Hair loss can be a real and never-ending nightmare for those going through it. However, this Nioxin System 4 Review will show you that hair loss isn’t permanent. With the right kind of treatment, your scalp can be healthy and stimulate proper hair growth.
