Good products
All have great minty smell. Shampoo is great - little amount is enough to wash hair. Leaves good feeling on the scalp. Makes hair shiny. Conditioner could have been better. Smell is good though. The scalp spray is a good product that serves as a filler and makes hair look thicker. However, hair doesnt stop falling or grow more.

Mñeh…
Not that good, it’s very aggressive with the hair. The product didn’t arrive complete, they never refunded the money

Excellent For Thinning Hair
This is a good product. Comes in a set. However, I had to complain about the Leave-In Treatment bottle that was not a full bottle (almost half full) ...The seller was also quite helpful, but unfortunately had to request a claim as I was unhappy about the Leave-In Treatment bottle in the box. I purchased 2 sets & both Treatment bottles were half empty. Thanku Amazon for the efficient after sales service. Still a happy customer 😊

If I had the option of give negative rating, i would
For the past 5 years, I have been losing hair from the crown of my head, at a very slow pace, but nevertheless been losing hair. I researched and I found Nioxin. From all the reviews on youtube, I was convinced so I ordered the system. I have been using the system for the past 3 weeks, and it has NOT solved my problem. It expedited my hair loss. After every shower, every 2 days, every time I stroke my head with the shampoo or the conditioner, strands of hair just come off. My tub gets filled with them. My hairline was never a problem, but for the past 3 weeks, I have noticed it receding too. First of all, the instructions arent clear anywhere. not on the bottle nor on their website. And after extensive research, I realized the youtuber whose video I initially watched and was convinced about this product, although he claims he's not 'Paid' by Nioxin; Has multiple Nioxin videos, interviewing them, and what not. Even on Instagram, all the before and after pics are sponsored by Nioxin. Guys please steer clear of this product, consult your doctors, or do your research on all channels and read comments

Good product Wrong Description
Overall this is a good product and slows the hair thinning process but does not heal or make your hair grow back. Issue is the size that says it is a 1 month supply thats a complete joke. It will last you a month if shower twice a week. This is like a weekly supply. Closer to travel pack than a trial pack.

So I’m skeptical about ALOT of products, especially hair growth ones but I decided to give this brand a shot when suddenly I noticed my scalp was super visible.. signs of losing hair. And I was constantly itching my scalp after only a day of not washing it. I started the product consistently in December, and now it’s may and I can confidently say it WORKED. My scalp isn’t as visible at all, and the itchiness is not as bad. I still itch slightly after 2 days of no washing but it wasn’t nearly as bad as before. 6 months is awhile to get these results but worth it. I stay try it out, and stick to it. Also this size of shampoo and conditioner was enough to last me 2 months at a time, washing my hair on average 2-3 times a week, with long hair. (I will say this brand makes my hair tangly after I get out the shower but not a big deal)

I have tried many things to improve my thinning hair and Nixon is the only product I’ve had visible improvement with. Been using it for a year now and my hair is getting thicker and scalp is healthier with some new hair growth.
