More lively after 1 use
Ok so I have to do this review bc it works! I've been battling hair thinning and ive tried a lot of products both topically and orally ...this is it...after one wash i saw my hair more lively and vibrant and shiny just after one use...not sure how it will hold up as far as making my hair thicker but I can already tell its making my hair stronger as well lively, so very impressed had to share So I had to come back and add pics bc it works and the pic says it all!! As u can see on the left is before I started using it and the second one is after only two times of using the shampoo and conditioner and I have used the mousse once which is in second pic! I washed my hair the same day these were taken and the left was from valentines day and the right one is from a day ago. As u can see the volume is undeniable!!! And let me also add that i tease my hair for volume purposes which I did one the left but I didnt even have to with this stuff, this is carzy! I have spent so much money on different products and to think I haven't tried this sooner, well im kicking myself in the butt!!

IT DELIVERS!
I’ve been using this shampoo for about six weeks, and the results are incredible. I’ve tried countless hair “systems” over the years (yes, even Mane and Tail), and this is the only one that has truly worked for me. I’ve added at least a full inch of length, and my hair is noticeably fuller. The bottles may look small, but a little goes a long way—use less than you think you need. For the results it delivers, it’s absolutely worth the price. I won’t be stopping this system anytime soon.

So Far, So Good!
Let me preface my review by saying that I haven't used the Nioxin System 4:long enough to comment on growth results, but I want to comment what I have experience with this product within the first two weeks of usage. Hair Type and Texture: -Relaxed and colored afro-textured hair. Hair Issues: Dryness, breakage and thinning. Product con: Small amount of product for the price, particularly the foam. I don't know how long that small can will last given that you have to use it three times a week to get results. Product pro: Despite the bottles only being 5 oz, this is the highest quality, most concentrated shampoo I have ever bought. The bottle may be tiny but the shampoo is so concentrated that it only takes a pea-sized or even less to fully lather and cleanse the hair. Because the shampoo is so concentrated, if you take your time to lather, rub the shampoo down the hair shaft and scrub your scalp, there is no need to rinse and repeat. The peppermint smells great and feels amazing when it tingles on the scalp. The first time I used the shampoo, my hair felt soft immediately. Same thing after I used the conditioner. Because my hair is very coarse and sometimes feels hard, my hair felt so much softer after using the shampoo. Today was my second wash. And while I still have experienced shedding, my hair is not breaking as much. I did a major chop on my hair today. (2/2/2025) to get rid of the damaged hair and pretty much start over. I washed my hair with the nioxin before getting my haircut and my hair feel so much better and softer. I also noticed much less breaking as I combed through my hair. I will do an update to see if this product helps with the growth and thinning, but so far I'm loving the quality and how it has made my hair feel. You really do feel a difference in your hair the very first time you use it.

Noticeable Results After FIRST WASH!!!
Glory be to GOD!! Thank God that I found this product! Thank God for the person who started this company! Thank God for the people who work at Nioxin! Thank God for my hairdresser who recommended it! And Thank God that IT WORKED!!! I'm an early 40's female. After the first time I had COVID, I noticed my hair was falling out. Not in "clumps" so to speak, but definitely more than usual. The hair loss had started about a month after and seemed to subside within another month or two. But after this last time I had COVID, just when I thought the hair shedding was getting better, it got worse again. I love baking and cooking for others, but my hair shedding got to a point where I thought I'd never be able to do that again. One of my BIGGEST FEARS was that someone would find a hair in the food I made. It did happen to my immediate family a couple of times, and that was bad enough. But if it happened with friends, neighbors, or at a church potluck?! Oh, that would be mortifying! It was stressful to say the least. I had my blood tested and no hormonal imbalances, no deficiencies. As far as I knew, I didn't have any hair re-growth issues. But the growth just couldn't keep up with the loss. When I washed my hair and combed it out, I could see scalp far too easily. I became concerned. To a point where I perused the wigs on Amazon...in case it came down to it. I also looked for hair growth shampoos, but I didn't want to pick just anything. I can be a bit of a conspiracy theorist when it comes to everyday products. Are these people truly offering me something that will help? Or will it hurt me only enough to try and get me to buy more product? How can I trust just any product off the internet? So, I asked my hair dresser. She recommended Nioxin System 2 for me. It seemed expensive, but I was willing to try it. And I was SHOCKED that after my FIRST WASH, I had significantly less hair loss! I wondered if perhaps my old shampoo had some chemicals that just killed my hair! I continued for a month, shampooing (It has a really good lather), combing the conditioner through my hair with my fingers, and adding the foam to my scalp with every wash. In the attached picture that shows my wash-by-wash progress, I finally hit a day where I had LESS THAN 15 STRANDS LOST IN ONE DAY by Wash 20. I was SOLD! Of course, I've continued to use it. After the first month, I changed from using the foam everyday to only 3-4 times a week. It's been almost 3 months now, and sometimes I still have 10 or so strands, and a little more so when I skip a day to wash my hair. But there have also been days where I've only had 2 or 4 strands of hair lost from my wash. IT'S TRULY AMAZING!!! Keep in mind that when I talk about hair loss on Nioxin (and the attached progress pics), I'm only referencing hair lost from the wash and conditioning. It's not reflective of a full day's loss. I had some in my hairbrush after, but not enough to make a significant difference. I rarely see loose strands on my shirts, and I haven't had one stuck in my bra since I started. (Ladies, you know the struggle. LOL) I love the minty scent! It's calming to me, and even more calming knowing that IT WORKS!!! I'll be honest. The foam does make my hair feel a little sticky when I put too much on. But it also makes my hair feel much fuller than usual and gives it great body! Before I purchased the product, I saw reviews with pictures of people with their face blotched red. The back of the foam bottle does say it's got a chemical that can cause temporary redness, but I haven't had any trouble with that. (But then again, I don't typically rub the foam on my face since it's supposed to be a scalp thing.) Also at this point, while I do see a little hair growth, I don't know if that's normal hair growth or growth due to Nioxin. It definitely doesn't feel too much thicker (without the foam), but I've heard your hair only grows 1/2 inch a month, so it will take some time. I thank God and Nioxin that I now feel like I have more of a chance to see myself with full, flowing locks again someday soon!

Works great
Wife loves this product, her big head isn't itchy after use and apparently sensitive to other shampoos. Scalp isn't flaky like it snowing on Xmas so thats great as well. Recommend this product.

Good Product - too small quantity
Good, only issue is the size is very small and thus the cost-vs-value isn’t good

It's working. I'm Very pleased.
I started using this product about 4 months ago. I've tried so many different shampoos for thinning hair that didn't work. This one is working, my hair was shedding so bad as I'm getting older. So much hair when I'd brush my hair. Hair was everywhere. Now there are only a few strands when I brush my hair. I also take a vitamin for hair thinning.

Two out of three product work
Changed to Nioxin because I had used the product years ago when I was dealing with stress related hair loss and had success and needed to change from what I was using. The product I was using worked to a point but I did not like that the product never felt like it rinsed completely out. I like the shampoo a lot, it cleans my scalp and rinses out completely. I am not a fan of the conditioner, leaves my hair feeling limp and my scalp gets greasy faster even with a small amount. I am still figuring out how to use the treatment product, no clear directions as to how much or if need to use on wet or damp hair. I will say that my hair is in better condition and notice less hair loss and shedding since I started using the product. Will definitely continue using the shampoo and the treatment but I do not recommend the conditioner.
