My Hair Has Never Looked Better! I've always struggled with fine, somewhat lifeless hair, so I'm constantly on the lookout for products that can add some volume and thickness. I'm thrilled to say I've finally found my holy grail with this shampoo and conditioner! From the very first wash, I noticed a difference. My hair felt **clean and refreshed** without being stripped, and it had a surprising amount of **bounce and body**. After a few weeks of consistent use, the change is undeniable. My hair feels significantly **thicker and fuller**, and it even looks healthier. I'm no longer self-conscious about my scalp showing through, and styling my hair has become so much easier. Not only does it deliver on its promises for thickness, but it also leaves my hair feeling incredibly **soft and smooth**, and it has a lovely, subtle scent that isn't overpowering (minty). If you're looking to add some serious oomph to your hair, I cannot recommend this shampoo and conditioner highly enough. It's truly transformed my hair!

1 month trial, just bought my second bottle. (Review from a 21yr old mom, with post partum hair thinning/loss.) So I’m gonna be really honest with y'all when I say I saw one comment on tictok about this specific product from a middle aged mom and instantly got it. I’m 21, I have a one year old and I’ve noticed that my hair has basically stopped growing after I had him, along with the usual thinning and hair falling out you might expect after having a baby.. I wanted to stop bleaching anyways so I decided to use this along side it and let my natural hair grow out. (Have tried without this soap before for 6 months with maybe a 1/4th in of growth 😭 so I’m not trying to be bias hah) So far, I’ve noticed that my hair has went from frizzy and dry to really nice and soft just with the base soaps, I don’t have to use much personally because my hair is naturally pretty fine as is. I like the nice neutral smell of mint that the whole set has, and I love the feeling of coolness on my scalp after it’s nice lol. As far as hair froth my hair is actually growing again I’m shocked! I don’t have much of a reference on how unbelievably slow it was before but this is not even a month difference and it’s a huge difference for me. Another little thing is that I now have baby hairs all across my hair line that are growing pretty rapidly. Only small con for me is that it does make my forehead all red sometimes, or my scalp but the foaming stuff does say it’s happens and it’s not painful or anything so that’s the only thing! Over all this product has personally done me very well for post partum hair loss and over all hair health I love it. :)

I guess it depends on the type of hair loss you have, but this kit didn't do much to help me. If your hair loss is due to a dirty scalp, then this will definitely help—my scalp is in the best condition it's ever been. I don't get flakes or dandruff at all anymore, and my hair is very soft and clean. Unfortunately, as said, fixing my scalp didn't do much for saving my hair. I have thinning hair from my mother, so my condition is genetic and not hygienic. The only product in this kit that somewhat helped was the step 3 mousse. It creates a thickening effect, which gives the illusion of fuller hair. It's a bandaid to the underlying issue, but, hey, I'll take any help I can get.

Menopause did a number on my hair and I will take any help I can get! I have tried other hair growth shampoo but this is my favorite. I am not yet sure if this is helping with regrowth, but it makes my hair and scalp feel great! I was worried that the foam would make my hair look and feel greasy but it doesn't. It actually makes my hair look and feel fuller! The price feels like a lot for such small bottles but they really do last for quite a while. You only need a small amount and I shampoo daily or my hair is a curly mess. I have fine curly hair that tends to be on the greasy side if I don't wash it. I love the smell and the tingly sensation it gives my scalp. I am hoping to see hair growth but even if I don't, I will continue to use it because of how much healthier my hair looks and feels.

Nioxin is a quality product that I have been using for years. I use it every single day without skipping, unless I am sick and in bed. Thin hair runs in my family, so I needed something effective to go along with rogaine. That used to sell this in all the salons, and now they only sell it here, so it made it a little more difficult, but I'm glad I can still get it. The thickness and effectiveness I see in my hair is amazing. My hair is growing faster than it's ever grown, so much so that I have to dye my roots more often. It used to be every 6 weeks, now I want to do it every 3 weeks because there is so much growth. Compared to my mother and daughter, who also have thin hair, the results are amazing. You can definitely see a huge difference in my hair, that You Don't see in theirs. I don't know why they haven't jumped on the bandwagon, but maybe it's because of finances. I highly recommend the system 2 for anybody with thin hair. Use it often, and you will get the results that you desire.

I like this hair combo product. The only complaint and the reason for 4 stars instead of 5 is that the foam, which is the main hair growth part, is not enough and doesn't last as long as the shampoo and conditioner do. I recommend doing a test before using it on your scalp. As it is mentioned in the product description and direction, the ingredients in the foam can cause a burning sensation and you skin can become red. For me it lasted about a few minutes the first time I used it and as I used it more the less the side effects got. The overall quality of my hair also increased. I just wished they had a bigger size foam.
