Nioxin System 5 Review: Pro’s & Con’s of this Hair Product

Nioxin Research Laboratories Inc. is a popular company with various product lines. The company was started back in 1987 by Eva Graham. Since then, they have produced numerous hair products, most of which have enjoyed enormous success. In 2008, the company was bought by Procter & Gamble.

This was quickly followed by various changes, including some minor refinements of the Nioxin formulas. The operations of Nioxin Research Laboratories were also moved from the United States to Mexico. Despite all this, the quality of their products has remained mostly the same. If anything, some of the products have become even more effective, and the overwhelming customer testimonials support the same.

Nioxin System 5 Reviews

Here are some of the top Nioxin System 5 reviews from other users:

“Have been using this for some time the seller is on time and the product is always packaged properly, no leakage. I was introduced to this by my sister after I finished Chemo, I now have a full head of hair even better than before cancer” By DARichards

“This shampoo and eating a certain diet are the only things that help with a scalp issue I have. When I am stressed or eat sugars and carbs or every time I work out, I get itchy oozing bumps on my scalp that scab over and sting. Someone suggested this shampoo on a blog after, in-depth searching and remedy, I broke down and purchased this shampoo. I’ve been using it a year and a half and has drastically soothed the condition. I also was losing hair, and now I have a ton of undergrowth hair. I recommend this product.” By Ashley

“I just used this for the first time, and enormous amount of hair fell out in the shower. I always get some hair loss when I shampoo, and even more when I dye my hair, but this hair loss is the most I have ever experienced, and I am a little freaked. Can you be allergic to this? Maybe it’s not right for everyone? Has anyone else had this problem?” By Eric James
