Effective for GLP1 hair loss
I was suffering from hair loss/thinning after taking GLP1 medication. Desperate, I went to my hairdresser and asked for her advice. She suggested I switch to the Nioxin system #4 for advanced hair treatment. She trimmed my hair and changed the style slightly to make it appear thicker.Once I received my trial sized set, I started using it every time I washed my hair. It was as easy as using any other product. I’d wash, condition and use leave in conditioning foam. Within a couple weeks, I noticed new growth by my scalp! I’ve been back to get the old growth trimmed off a few times. My hairdresser has commented about my hair looking healthier. Most of the time it cleans and moisturizes enough that I only use it every other day.When it was time to buy more products, I bought the larger sizes and pumps. I am very pleased with the success I’ve had with these products! Thank you, Laurel Wilson (my hairdresser) for recommending this to me!

Impressed with the Thickness and Fullness Results
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.

If your shiny bald head needs hair growth…consider this product
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.

Noticeable Volume and Healthier-Looking Hair!
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.

Good shampoo post chemo + for arid climates
My friend’s oncology nurse recommended this shampoo to her after she finished chemo sbd her hair started growing back. (She’s in remission, yay!)Anyway I was staying with my friend on a visit sbd used some and liked it. I bought a bottle of my own, and it’s been great for my hair. I live in the desert SW and the climate here makes by fine hair so dry and brittle – but this shampoo really helps keep my hair soft and fuller looking

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.
