Nioxin System 4 Scalp + Hair Thickening Shampoo for Colored, Dry, & Damaged Hair with Progressed Thinning | Maintain Vibrant Color | Cleanse, Nourish & Boost Hair Density with Niacinamide & Biotin

I’ve been using Nioxin System 4 Shampoo for a few weeks now, and I’m impressed with the results. My hair feels thicker, looks fuller, and my scalp feels refreshed and clean without being stripped of natural oils. The shampoo lathers nicely and rinses out easily, leaving hair soft and manageable. I’ve also noticed a reduction in breakage, and styling feels easier overall. The scent is light and pleasant, not overpowering. While it’s not an overnight miracle, consistent use really makes a difference in hair volume and scalp health. Definitely a good choice for anyone dealing with thinning hair or looking to maintain healthy, thicker-looking hair.

I love this shampoo. My hair turns out great and it has a nice smell

My spouse has a bald spot. it appears this helped. I watched as tiny thin hairs filled up the silky shiny spot and lite regrowth happened. I watched daily as thin sprouts became longer thin sprouts. If you ever had a part in your hair and followed it to point where it would end at back of scalp top...that's the spot I'm talking about. Rogaine does one area. Other products do other areas. This one got the spot in-between I hadn't seen advertised. don't know if it works for your head, but maybe they have the something that cleans those pores enough to allow sprouts to appear. Hair loss is hard on people, but it was lite weight and cleaning and seemed good quality. I have thinning hair but haven't tried it yet as a woman as didn't want to take his shampoo from him. I have no stories from woman point a view. Only from view above...looking at my man's bald spot and watching him feel more excited at new growth. Which is what we want in a great product.

I wish I’d done before photos because this stuff really works and fast. I’m 50 so was having hair loss at the temples and after a month of using this I have baby hairs growing in there. It no longer looks so bare.

My scalp feels very clean when using this shampoo,hair feels dry during shower but as long as i use conditioner, it’s good. I noticed less hair falling after shower

I’ve been using Nioxin System 4 for a few months and I’m really impressed. My color-treated hair is usually dry and fragile, but this shampoo has helped it feel thicker and fuller without weighing it down. I’ve noticed less breakage and shedding, and my scalp feels much cleaner and healthier. It lathers well, rinses clean, and doesn’t strip my color. My hair looks denser and has more body, especially at the roots. If you have dry, damaged, or thinning color-treated hair, this is definitely worth trying.

I don’t ever write a review. Mostly because I’m lazy. But I just had to write one for this product! For the first time in forever, there was NO hair on my drain cover when I washed my hair this morning! ZERO! I’ve been using this since July. I leave it on my scalp for a few minutes once I work it in then rinse. The photo is the hair off my brush. It used to be GOBS of hair! It would fall out in chunks even. I’m so happy I tried this! If you’re on the fence, give it a shot. You have nothing to lose, but more hair.

I’ve been using the Nioxin System 4 Conditioner (paired with the matching shampoo) for a few weeks now, and the difference is impressive. My hair is color‑treated and has been thinning for a while—this lightly moisturizing formula feels gentle yet powerful. It leaves my hair feeling soft and manageable, without any heaviness or greasiness. The texture is lightweight, yet hydrating—from scalp to ends. It’s formulated with peppermint and wild mint oils that invigorate the scalp, while caffeine, niacinamide, and biotin help strengthen hair at the root and promote a healthier scalp environment. Since using it regularly, I've noticed less shed during brushing and shower drain buildup, which used to clog weekly—now it's only occasional. My hair feels thicker and fuller overall, although I didn’t expect a dramatic regrowth—more like restoration. It helped stop the progression of hair loss; not necessarily added growth.

Es una botella más grande que la que viene en el kit lo cual me sorprendió porque pensé que sería algo similar. Llevo meses usando el producto y mi cabello dura más tiempo limpio. El cuerpo cabelludo se siente bien lavado y no grasoso.

My wife only uses nioxin on hair salon's recommendations, and it seems to have a good reputation. I order it , she uses it. She seems to do well from this particular deal, bless.

Very good been using it for a long time
