Hair Fall Defense Intensive Daily Leave-In Hair Treatment | With Niacinamide, Caffeine, Lauric Acid, and Sandalore | For Thicker, Stronger Hair | 2.3 Fl Oz.

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.

It works. I started using it in May and now I can see a big change. After using for 1 month, I can see lots of new baby hairs. Now my baby hairs have grown long enough as bangs length. As for anti fall, it helps reduce the hair fall, especially when it drys and you try to comb it. I can see almost no hair fall when I comb my dry hair. I can tell the new hairs are stronger and grow fast. The only negative thing I can say is the price. But do take a chance while it is on sale to stock a few bottles.

I’ve been on the hunt for a good serum that contains both caffeine and niacinimide as those ingredients are shown to help with scalp health and hair loss. This product checks all the boxes for me, but my one problem with it is that it is incredibly heavily scented. I have to be careful how much I apply because one too many sprays will give me a headache.

I have been using Nioxin products since the 90s. My weight fluctuates a LOT and every time I hyperfocus and loose 60-80lbs, I have a huge hair shedding event, just as bad as when I had each of my kids, so I've lost over 50% of my hair in a short time probably 6-8 times in adulthood. THAT SAID - THIS NIOXIN PRODUCT SMELLS GROSS!! Like, I wanted to run and shampoo immediately, but I had to get ready and go to work! The Night Density Serum is so much better and smells lovely. More masculine-presenting individuals might not find this repulsive, but as a green-floral sweet scent-loving feminine person, this is not it!

I've been using this along with the required shampoo and conditioner from Nioxin for over a year. It has slowed some hair shedding but hasn't stopped it and hasn't caused any regrowth. Probably going to stop all of these soon due to cost and lack of stopping the fallout and no regrowth as others experienced.

I cannot express enough how impressed I am with the Nioxin Ultimate Power Serum. As someone who has struggled with thinning hair for years, finding a solution that actually delivers on its promises has been a game-changer. This intensive daily leave-in hair treatment has transformed my hair, leaving it thicker, stronger, and more vibrant than ever before. One of the standout ingredients in this serum is caffeine, which works wonders for stimulating hair growth. Caffeine has been shown to promote blood circulation to the hair follicles, resulting in increased hair density and thickness. The inclusion of lauric acid, niacinamide, and sandalore further enhances the serum's effectiveness, nourishing the scalp and promoting healthier, more resilient hair. What sets the Nioxin Ultimate Power Serum apart from other hair treatments is its lightweight and non-greasy formula. I have tried numerous products in the past that left my hair feeling weighed down and greasy, but this serum absorbs quickly and leaves no residue. It is a joy to use and does not interfere with my styling routine. I have been using the Nioxin Ultimate Power Serum for several weeks now, and the results are truly remarkable. Not only have I noticed a significant increase in hair thickness, but my hair also feels stronger and more resilient. I have experienced less breakage and shedding, which has boosted my confidence and allowed me to style my hair with ease. The packaging of the Nioxin Ultimate Power Serum is sleek and convenient. The 2.3 oz size is perfect for travel, ensuring that I can continue my hair care routine wherever I go. The pump dispenser allows for easy and precise application, eliminating any wastage. I highly recommend the Nioxin Ultimate Power Serum to anyone looking to transform their hair. Whether you struggle with thinning hair, hair loss, or simply want to enhance the overall health and appearance of your hair, this serum is a must-have. Experience the power of caffeine, lauric acid, niacinamide, and sandalore, and say hello to thicker, stronger, and more beautiful hair.

Good product.

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.

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)

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!

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.
