## Description

Nioxin Pro Clinical's Hair Fall Defense Serum is a leave-on scalp treatment for thinning hair. Designed for daily use, it's clinically proven to increase hair anchorage with visible results in only 8 weeks* while thickening hair from the very first use. It's formulated with innovative ingredients including SANDALORE™, caffeine, lauric acid, and niacinamide. Together they work to stimulate and nourish the hair follicles to prolong the growth cycle and improve hair resistance for fuller-looking hair. This effective leave-on scalp treatment is the first time SANDALORE™ has been leveraged to stimulate hair follicles and improve hair anchorage. *Via improved hair anchorage; average results in 8 weeks, in a double-blind clinical study with 120 panelists.

Review: 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.
Review: Highly Recommend! - 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!

### ⭐ Awful smell, caused eczema flare-up :(
*by D***Y on April 14, 2025*

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?!
