On its own, you won't see a big difference, but if you combine it with one of Nioxin's kits, then you will see a big difference!

After two months of daily use, I can confidently say that at least on my own hair, it did nothing. On the contrary, I have been experiencing hair loss recently. I didn't even feel like it strengthened my hair.

I had intense hair loss for months. I did blood tests and had low iron. My doctor recommended iron and folic acid supplements! Almost always hair loss (if not hereditary) is related to deficiencies in the body. My hairdresser recommended the treatment with nioxin, and combined with iron, I saw a HUGE difference. Reduction in hair loss, many new sprouts, and existing sprouts getting longer!!
Now I also started using the shampoo-conditioner! If someone wants the shampoo, for me it is necessary to get the conditioner. The shampoo leaves the hair somewhat stiff. I hope this is equally good as the treatment!

I cannot have a definite opinion that it does the job. However, I am satisfied. The only negative thing is that, in my opinion, this specific product is not suitable for everyday use as it made my long hair a bit oily... unless I needed to use a smaller amount. Nevertheless, it is a top range for hair loss
