Nioxin 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’s rare that I review a product but this one needed to be written. I’ve had problems with the thinning of my front hairline. It’s been a huge insecurity of mine. I started using this daily almost a year ago because of a recommendation from someone on instagram. I did not have a lot of confidence but I saw the transformation of her hair and thought.. ehh I’ll give it a try. My hair is so FULL! Everywhere.. but the way it is soooo noticeable on my hairline is mind blowing! I started noticing the difference quick. I am so much more confident. Don’t hesitate.. just buy it and be consistent.. you’ll see huge results!

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?!

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

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.

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.

I have been using this product consistently now for about 3 months, and I have to say I absolutely love it. My hair is definitely thicker and stronger than it was before. I am also very surprised at the people who are going on about the smell. It does have a scent, but it's a very clean & minty scent that I actually really like, and have received compliments on- so it's funny to me to see people saying the smell is horrible. I completely disagree. I will also say that I do not use this product alone. I use the Nioxin Night Density Rescue Serum, the Nioxin System 2 shampoo/conditioner kit, and I also take prescription Finasteride and Minoxidil. I have found that the best way to get amazing results is to do multiple things simultaneously that are proven to get results. Sure, I'm not exactly sure which of them is doing the most help, but I think together they all do the best job. Way to go, Nioxin!

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.

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)

I’m happy to say that it seems like NIOXIN is working for me. I’m experiencing hair loss due to getting older.. after three weeks of use, I can visibly see that I am not losing as much hair when I wash and when I brush my hair. I personally don’t care for the smell. It’s not too strong. It smells less after the first day. I definitely recommend and I will be buying this again.

This stuff works. I see a lot of comments saying it doesn’t but this product isn’t meant to create new hair growth, it’s to stop your hair from shedding like crazy. I noticed a huge difference in how much hair was in my brush every day. I stopped using it for a week and there was a noticeable amount of hair falling out compared to when I used it. The only complaint is the smell. Somewhat overwhelming in my opinion. Will repurchase.
