Nioxin's Serum Reduces Hair Shedding and Thinning

I’ve subjected my hair to over 15 years of heat styling. As you can imagine, it’s taken a visible toll on my strands time and time again. Now, I have to constantly rely on hair-strengthening and thickening products to improve issues like a thinning hairline, brittle ends, hair fall loss, and a flaky scalp. Needless to say, my hair needs all the help it can get, which is how I found the Nioxin Hair Fall Defense Serum. 

This scalp treatment is specifically formulated to improve the appearance of thinning strands. It contains strand-strengthening ingredients like caffeine and sandalore that stimulate hair follicles, which in turn reduces excessive shedding and promotes a thicker mane. Some studies have even shown that caffeine can help block dihydrotestosterone (DHT), a hormone that plays a role in hair loss. Meanwhile, niacinamide is another key ingredient, which has hydrating and anti-inflammatory properties to soften strands and soothe the scalp. As a result, it creates less breakage alongside a healthy scalp environment, which is ideal for potential hair growth. 

The thickening serum is easy to incorporate into your daily routine, too. Make sure to evenly massage in the leave-in formula after applying 15 pumps to the scalp (particularly on dry or damp hair) daily to see fuller-looking, stronger tresses over time. 

I can attest that Nioxin’s hair growth formulas don’t disappoint. I’ve tried the System Kit 3, which consists of products with nearly the same ingredients (such as caffeine and niacinamide) as this anti-shedding serum. My weakened strands are typically slow at growing, especially after constantly using flat irons and blow driers. However, the shampoo and conditioner set improved my hair’s density only after a few uses. That said, the Hair Fall Defense Serum is bound to be just as impressive too. 

But don’t just take my word for it  — reviewers also found this Nioxin hair growth serum to be transformative for thinning strands. “Not only have I noticed a significant increase in hair thickness, but my hair also feels stronger and more resilient,” said a shopper. Other customers similarly shared that they have a “whole new layer of baby hairs” and their hairline “thickened up” after a few months of using the product. Keep in mind, though, a few users noted that the sandalwood scent can be overwhelming, in case you’re sensitive to strong fragrances or have a sensitive scalp.
