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.

Good product.

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.

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!
