Nioxin shampoo is designed to help people who are experiencing thinning hair. It has been around since 1987, and it has been helping people with hair loss or thinning hair ever since. Nioxin is a scalp treatment and hair care stem, and it thickens hair. 

Nioxin comes in different three part systems, depending on your hair type. It has a cleanser that removes dirt and debris, as well as sebum that blocks the follicles.

The second part of the system is a revitalizing conditioner. Then, it has a scalp and hair treatment. The different systems are for different hair types. Natural hair may not need a lot of additional moisture, while color treated hair needs some moisture.

Chemically treated hair needs a lot of moisture. There are six different kits, two for each of these hair types. The two systems are different because one is for hair with light thinning, whereas the other is for hair with progressed thinning.

If you are experiencing hair loss, you should start by finding out what is causing your hair loss. It is important to find out because it could be environmental factors, such as nutritional deficiencies, hormonal imbalances, medications, medical conditions, and more. 

If you are a good candidate for Nioxin shampoo, you need to use it continuously for it to work. If you stop using the shampoo, your hair could revert back to the same pattern. As long as you are using Nioxin shampoo, you are likely to see some results.

How to Use Nioxin Shampoo

Nioxin has a three part system. The first step is to clean your hair. The cleanser will remove sebum that can clog up your hair follicles. It also lifts dirt, fatty acids, and other residues from the environment from your hair.

You need to wet your hair thoroughly, and then you can gently massage the Nioxin shampoo into your hair. Clean your scalp and let it sit for one minute before you rinse. The next step is to use the conditioner. This will hydrate your hair and add moisture back in.

You can apply it to your entire scalp and hair, or you can stick with the hair from the middle down to the ends. The conditioner controls the moisture in your hair, and it helps it stay hydrated. 

The third step in the system is a scalp treatment. If you want your hair to appear thicker and fuller, you can apply the leave-in in the third step. You should distribute it evenly throughout your entire scalp. Make sure that you use it as needed and follow the directions if you want it to work.
