Good 👍, 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)–and 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 mother–if 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!

It really works
I’ve used nioxin products for years. This is the best of their products. I told a friend about it, she has been losing a lot of hair. She said the first time she used it there wasno hair loss, and has used it several more times and is amazed. Not only am I losing less hair, my hair is fluffier and shiny and fuller looking.

Effective!
I wanted to wait until 2 months after use before posting my honest review. I’ve 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. I’ve been doing this twice a day. My hair is fairly healthy, but I’ve been having issues with shedding since summer. I have fine hair that’s low density. What I’ve 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 “lessen” 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 don’t smell anything doing this. The serum doesn’t 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 don’t 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 it’s a great product and I will continue to use it.

Awful smell, caused eczema flare-up :(
I don't know how well this product works because I simply could not get over its pungent fragrance. Gross. Listen, I love Nioxin. I've been an avid fan and daily user of its various leave-in products for years. YEARS. But, this is the first Nioxin product I had to throw out because it just smells SO BAD. The smell is not only pungent and strong, it's just straight-up bad. It smells like an incredibly offensive men's cologne - like cigars, tobacco, whiskey, smoke, and alcohol. It's so strong that it caused an eczema flare-up on my neck!! That was the final straw for me - if it hadn't triggered that eczema flare-up, I would've done my best to ignore the fragrance and I would've continued to use this product to test its effectiveness. But, after just three (3!!) uses, my neck became super red, itchy, scaly, and inflamed. Once I stopped using the product, my skin completely calmed down. I wanted to give Nioxin the benefit of the doubt so, after a long pause, I picked this up again. Bad idea. Alas, just three (3) uses in, once again, my eczema flared-up like crazy. This is definitely a NO-GO for me. Nioxin, can you PLEASE make this fragrance-free or with a lighter fragrance?!

Stinky
Good product. Absolutely horrible smell. Not sure how long I can use this because I can smell it all day long. I used it before bed and the smell wakes me up it’s that intense

Not worth the money.
I am on my third bottle of this and I've been using it for over 4 months. I have seen a small amount of improvement, no miracles! I used to use their product that had minoxidil in it and swore by it as it was so good. This is much more expensive and not as effective. I bought it twice on sale for half price and I would not pay any more than half price for it. I also do not like the very strong fragrance that is overpowering and smells like cheap hairspray. I will be looking for a different product to purchase.

Smells like aftershave strong
No idea if this works. Only used 3 days. I will update review in a few months with info if it works. This review for smell: smells like aftershave. To me it smells nice and I don’t mind it. If this actually works and make me lose less hair I’ll smell like aftershave no problem. Will use for three months and then update this.

I had a kidney transplant so the medication makes my hair shed like crazy then my doctor put me on a GLP1 to keep my weight at 120lbs and that was the worst, lost A lot of hair. Tried every thing rosemary oil and shampoo eneed with dry nasty curly down to my wast with knots, Got a hair cut Tried this STUFF one Time and WOW! my hair feels great there was not annoying hair in the drain and the leavin serum is amazing. The price is worth it! I also bought the conditioner and the night time leave in serum I LOVE IT. Thanks Nioxin!!

It works amazingly
I bought this serum in May and have been using it consistently twice a week since then — and it’s been fantastic! My hair was shedding a lot due to stress, but now it feels fuller, healthier, and more beautiful. I’m genuinely so happy with this purchase and will definitely be buying more. Yes, the scent is very strong — and I’m 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 isn’t a hair growth serum but a density booster — 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!
