Good ๐, but Predatory
Good products and I LOVE the kit, but the price gouging is insane.. I told my aging mother about this product and she went and bought it too.. I don't know what price SHE ended up paying for, but I guarantee it was much more than what I paid for it. Which is Predatory and I expect better from a brand that is WHITE LABELING from China factories [White-label products are sold by retailers with their own trademark but the products themselves are manufactured by a third party]. I only paid $31.64 TOTAL for the whole kit (which who's to say its even worth that)โand now its listed for $69.00 ($6.63 per fluid ounce) which is more than DOUBLE what I paid for it.. Do better you scummy bottom of the barrel scammers! I love the anti fall serum, the form factor, the smell is amazing, and it does what it says it does. Im proud of the INCI list, as I am a hawk when it comes to reading INCI lists.. But not for that new price thats listed.. I love the lather of the shampoo, how it makes my hair feels, less hair fall in the drain, but not for that new price.. I totally would purchase this again! ONLY if it was back listed for the original $30 that I paid for ORIGINALLY. I feel sorry for my poor mother who is already getting old and already has to deal with the menopausal affects of hair loss, so not only does she have to deal with loosing hair from getting old, but also has to deal with getting outright scammed IN THIS ECONOMY for her coins! Now she's a victim of price gouging. Not cool Nioxin! CEO Eva Graham should feel ashamed of this type of behavior and I hope she thinks about her mom if she reads this! Customer service and 'Wella Operations US LLC ' can send an extra kit and I'll mail it straight to my motherโif they choose to make up for it in any way shape or form. FYI if you were to still sell at $30 you STILL are making a decent profit margin, so stop being greedy and do better! You gain more long-term revenue through higher sales volume, stronger customer loyalty, repeat purchases, and trust-based brand equity instead of maximizing for short-term margin on each product. The lower unit margin would be offset by stronger repeat purchase behavior and higher lifetime customer value, the The Ordinary for example!

Effective!
I wanted to wait until 2 months after use before posting my honest review. Iโve been using Nioxin hair serum consistently for about 67 days. I apply it directly to my scalp (I part my hair into sections, then spray), I then use a scalp massager massaging my scalp for 3 minutes. Iโve been doing this twice a day. My hair is fairly healthy, but Iโve been having issues with shedding since summer. I have fine hair thatโs low density. What Iโve experienced since I started using is little to no shedding- definitely shedding less than the normal 50-100 strands. In the 2 plus months I have about 2 inches of hair growth (I purchased one of those hair growth tracking tshirts). I find many serums/oils boast hair growth, but few talk about growth retention. My hair is stronger and most importantly thicker. Overall I love it and find it to be very effective! Now a very small minus is the smell which takes some getting used to. The product has a sandalwood smell which I am not a fan! What I did to โlessenโ the smell is I apply 1-2 small sprays closely to my scalp then I spread the serum across my scalp using my finger- I donโt smell anything doing this. The serum doesnโt make your hair oily or greasy after applying. You can use sparingly (1-2 pumps) then use a scalp massager to spread it around. I purchased for 50 USD, but I feel like this will last me 4-5 months even applying twice a day. I donโt think it has protein in it which is great because I am protein sensitive and I find many of the popular hair oils contain protein. Overall itโs a great product and I will continue to use it.

Stopped my excessive shedding in 2 days!!!
This stuff is AMAZING! I had been noticing my shedding a lot more than usual lately. It seemed everytime I touched my hair I was loosing strands and I was started to get scared. I went to the doctor and found out I have low iron and low vitamin D which Iโve been taking vitamins for but in the meantime I wanted to get something that could stop the excess shedding before I ended up with bald patches. After the first wash and night of using the serum, the difference was insane!!! Iโve only been using this product for 3 days so far but I already see a HUGE difference in the amount of shedding. I loose maybe 20 strands of hair a day just from regular brushing which is a normal amount, considering I was literally loosing 2 to 3 clumps of hair before. The serum does have a strong smell but I just apply it at night before bed and the scent is gone by the morning. The shampoo does state to use daily but due to my hair being dry and curly I only use it twice a week, despite that Iโve still seen great results!

Caffeine sensitive people be aware
4 stars because I think this really works just isnโt for me. I really wanted this product as it has so many positive reviews for its intended use which is retaining existing hair and cutting down on shedding. I have caffeine sensitivity and did see it was #4 ingredient in the label so I was concerned but I had no way to know if topical application would produce similar results as ingesting caffeine. Well, it did. After 45 minutes it produced a fast heart rate over 160 and adrenaline rush similar to if I had drank too much caffeine. If only lasted an hour versus 4 hours from ingesting. Just be aware if you have this problem but otherwise I hear it works great. Disappears into the hair with no residue and does not affect styling or cause buildup. Wish I could use!

Smells so strong and bad it made me nauseous
Do not buy this if you are even the tiniest bit sensitive to smells. And itโs a personal care product so you canโt return it. The smell was SO STRONG and nothing I did made it go away. After a few hours of constantly smelling it in my hair it started to make me nauseous every whiff I got. I didnโt use it long enough to be able to review if it works or not. But there are plenty of other products out there that do the same function and donโt make you stink to the high heavens in the process.

Strong smell, caffeine kept me awake
I have been using Nioxin night density rescue serum for over a year and seeing some results, but I don't like how oily it makes my hair, so I decided to try this Nioxin hair fall defense serum when it went on sale due to the good reviews. Good news is it isn't oily, but I realized quickly that I should have listened to the not so good reviews. I am apparently one of the few sensitive to topical caffeine and also the sandalwood scent. The scent is overwhelming to me and lingers all day, giving me a headache, plus when I used it at night I had trouble sleeping, I assume due to the caffeine. So it's back to the other serum for me. BTW, the reason I'm using such products is due to very fine hair that has been thinning as I age, and then 2 cases of COVID in 2 years made it worse.

Clean hair
I was loosing hair due to stress and my hairdresser daughter recommended this to me and with this shampoo and hair vitimins but not loosing as much hair now. My hair was falling out in clumps and now i have a few strands in the drain. It tingles a little on the scalp and it makes me feel like it must be working, the tingle in a good way, but my hair and scalp feels clean.

Sensitive skin - smells amazing!
I have only begun using the product within the last week, so I havenโt seen any growth results yet. I will update my review later for that. What I can say is that my extremely sensitive skin is completely unbothered! I am usually very reluctant to change anything on my hair routine because my skin is so sensitive. But no breaking out has happened after applying the product!! Also, if nothing else, the smell is AMAZING!!! Even 24 hours later, my hair still smells so good from the spray.

It works amazingly
I bought this serum in May and have been using it consistently twice a week since then โ and itโs been fantastic! My hair was shedding a lot due to stress, but now it feels fuller, healthier, and more beautiful. Iโm genuinely so happy with this purchase and will definitely be buying more. Yes, the scent is very strong โ and Iโm someone who usually avoids strong smells, especially before bed. But I found that applying it early in the morning works perfectly; by nighttime, the scent has faded completely. This isnโt a hair growth serum but a density booster โ and it absolutely delivers on that promise.

Expensive incense smelling caffeine hairspray
Honestly save your money, the only ingredient that's helping here is the caffeine. The research around benefits of sandalore is very preliminary and apart from making your scalp smell like incense it's likely not doing anything. If this was a more appropriately priced I would rate it higher (maybe)

Great so far!
Purchased this alone with the shampoo. I've only been using it for about a week so haven't seen a huge difference yet, but I love Nioxin products because they actually do what they say, so expecting great results. The scent is quite strong, but I like it so it's not a problem for me. I usually put this on at night because I have really fine hair that gets weighed down pretty easily. That said, this doesn't leave hair a sticky goopy mess so I could probably wear it during the day if I was so inclined. Note - first application I went a bit crazy and it does cause a bit of tingling but this only lasted for a minute or so. Use it sparingly!

Wife made fun of my bald spot... Decided to do something about it.
So... As the title says my wife made 1 joke about my bald spot. So the million dollar question does it work? Yes... It kinda does actually work. I've been using it for the past 3 weeks, not as consistent as I would like to but enough where it's 5 days a week. Where today she noticed "oh it's growing back a little bit" Now will it grow all the way back and not be a bald patch, that is the question. So a solid 4/5 because my hair is slowly coming back.
