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.

So far this product is working for me. Im a bariatric patient that experienced hair loss, and this product has helped. Though it doesn't produce instant results i am seeing hair regrowth. Especially around the crown of my head and edges of my scalp. It does have a bit of a chemical smell to it so I would apply this at night before bed.

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!

I absolutely love this stuff. I have tried so many hair serums at this price point & higher. This is the only stuff that has actually worked. I am perimenopausal, have hypothyroidism, had Covid, & a lot of stress. I went through a horrible shedding phase. The shedding improved significantly once I started using this stuff. It didn’t stop it completely & anyone who claims a hair serum can do that is probably lying through their teeth. But this stuff did help. I think the stress & post Covid hair loss just had to run its course, & I got my medication sorted for my thyroid, but while in the thick of all that, this stuff absolutely worked. Now that the excessive shedding stopped, I still use this stuff religiously & I do believe it has aided significantly in the strength & regrowth of my hair! I also love the smell too. It has a high end gender neutral sandalwood scent.

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 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?!

It works so good in my scalp. It feels fresh and it’s not too strong in the scalp. smells good
