My husband buys it for me just to save our drains now.
By Michigan mom on Reviewed in the United States on April 16, 2025
Listen, I don’t usually get emotionally attached to shampoo, but Nioxin System? We’re basically in a committed relationship now. It’s not the cheapest shampoo out there, but that also usually means it actually WORKS!… if you’re tired of your hair looking like it’s going through an existential crisis, this is the stuff. I started noting in my phone notes how much hair was falling out after every shampoo, because it used to be a lot. And after 7 times of using this I was down to just 2-3 hairs instead of a handful!! After a month, I swear my hair started staging a comeback tour. 85% of people said it thickens—I’m pretty sure the other 15% just weren’t using it right. My hair feels fuller, denser, and way less sad. Like, it finally RSVP’d to the party on my head and brought friends. I also didn’t have to use nearly as much as I used to: a much smaller amount of it lathers up JUICY!!! So good! So I’m not going thru it nearly as fast as I thought I would! And it smells great: no strong smell to it really as all. The real MVP here is the scalp situation. This shampoo is like a juice cleanse, but for your follicles. It gently kicks out all the gunk and leaves your scalp feeling fresh, not like you just scrubbed it with regret and bad decisions. Plus, with niacinamide and biotin in the mix, it’s basically feeding your scalp a five-star brunch. Is it magic? No. Is it science wrapped in a fancy bottle that actually works? Absolutely. Final verdict: it’s easy to use, effective, and My hair’s thicker, my scalp’s happier, and I no longer cry in the shower. 10/10 would lather, rinse, and repeat.

I can't believe what the market will bear
By Paul Hanley on Reviewed in the United States on March 26, 2025
Good shampoo, but I cannot believe people are paying more than 20 bucks for this. I bought it repeatedly for $12... It's a good shampoo for me, but the price needs to return to normal.
