I bought this shampoo because my hair is thinning. I used it before and should never had stopped. My hair is so full. The texture is different also, in a good way though. Its like squeaky clean, but not dry at all. I do use a tine bit of conditioner on the ends of my hair. Im in love with shampoo. My scalp feels so clean and invigorated. Great shampoo

This is high quality shampoo. I have used system 1 and 3 and I have found that 2 is right for me. I don't think that I have thinning hair beyond natural aging. However, I like that it makes my hair feel thicker and stronger. I like the way it foams up, and it smells like it is being activated. My hair looks very nice after using this and the system 2 conditioner. I definitely recommend using the shampoo and conditioner together.

I'm amazed to say, this shampoo really does make hair look thicker and helps a good deal to obscure thin patches on the scalp. I'm usually very skeptical about product claims, but I'm delighted to say I was mistaken to doubt this product. I've been using it for about two months, and after just one month, the thin patches on my scalp were considerably less noticeable; two months in, running my hands through my hair, I can even feel that it's thicker. I've read that the ingredients in these products don't actually promote new hair growth, but rather, enhance the hair shafts to make them appear thicker. However it works, it decidedly works, and works better than I ever expected. I use the shampoo with the conditioner from the same Nioxin system. I've tried the leave-in serum, too, but I'm less enthusiastic about that product. When they tell you to wash, condition, and then use the serum, what they DON'T mention is that the serum - not surprisingly come to think of it - temporarily stiffens your hair, so that unless you're accustomed to styling your hair in some inflexible, "wet-look" style, your hair will not be styleable in the way you'd usually prefer. From what I've read, the ingredients in the serum don't really do anything more than what the shampoo and conditioner do, so I'm not using the serum any longer. But the shampoo and conditioner are very effective, and for now, I don't see myself using any others any time soon. The price is not ridiculous, and the two products are worth it. I'm going to post this review for the conditioner, as well.

I Ordered this for my daughter, who is 18, and who has suffered from hereditary "pilar cysts" that form on her scalp. She has other scalp issues, possibly related to her Hashimotos Thyroiditis, that have been causing inexplicable hair shedding and an overall overactively oily and inflamed/dandruff afflicted scalp since age 9. I have tried many things including prescription, detergent-like shampoos that have not helped much with the hair loss and scalp. However, I find it very interesting that her pilar cysts, which usually had to be surgically removed, have begun to remedy on their own since using this product. There are two things I can possibly attribute this to: 1. Using an otc "hair vitamin" that contains biotin (she has used these before and never had much effect, and never affected the cysts) 2. This shampoo. As I said, she has suffered with these cysts for a decade and tey never remedy themselves, and always get to the point where we have to regrettably have them surgically removed by a dermatologist. She had one just "burst" on its own (did not notice, just saw a small scab that took a few weeks to go away). Now, a second one, which ironically reappeared after two surgical interventions in the same spot, has begun to soften and look similar to the one that had burst. I am hoping that this shampoo is the reason and that it is somehow causing the cysts to break down. This is just my theory, but if you suffer from these blasted awful things, you will know that if it can save you from a trip under the knife, it would be great. The cyst that ruptured healed as well or better than the surgically excised ones she has had. As far as a shampoo, while I do not see a huge difference in hair growth or dandruff, her oily hair is cleaner and healthier looking post use. I do not bother with the mousse-like step of this program or the conditioner, which is not very detangling. The shampoo is great. Nice scent that isn't bothersome or overly medicinal and it lathers very well on her very thin hair, making it easier to clean the scalp.

I’ve been really impressed with this shampoo. It leaves my scalp feeling clean and refreshed without stripping my hair, and I’ve noticed my hair looks fuller after consistent use. The tingling sensation feels invigorating, and a little goes a long way. Great option if you’re looking to support thicker looking hair while keeping your scalp healthy. Would definitely repurchase.

I've been using this for decades after losing a bunch of hair in my 30's having used Head and Shoulders. I am now 70 and still have a decent head of hair. And never any dandruff.

This shampoo has been great for thinning hair. It leaves the scalp feeling really clean and refreshed without being too harsh. Over time, my hair feels a bit fuller and healthier, and it seems to add some volume as well. The formula is lightweight and rinses out easily. Solid option if you are looking for something to support thicker looking hair and overall scalp health.
