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.

Unleashing the Power of Nioxin Ultimate Power Serum - Say Hello to Thicker, Stronger Hair
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.

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.

Can’t stand the smell
I just can’t stand the smell and anybody who is around me can’t stand it either I notice. They would ask what soap or shampoo I was using? I would ask why? They wanted to know so they could avoid buying it! I use this about 10 years ago maybe less and it had no smell and it really worked. My hair came back straighter and thicker. I didn’t even have to blow dry it. I would just shake my head and it gave me the best beach wave I’ve ever had without any work. if I got caught in the rain, it was fine absolutely no frizz after. I couldn’t believe it. I was so happy but I stopped using it because it was quite expensive at the time. It seems so different now. It’s too bad.

Caffeine sensitive people be aware
4 stars because I think this really works just isn’t 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!

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.
