I bought the NIOXIN 3 PART SYSTEM NO.1 for normal hair that has a thinning tendency. Unfortunately I only have this photo featuring the treatment bottle. Anyhow, I used for at least a month the whole treatment in 3 steps: shampoo, conditioner and treatment.   Did it work? If you ask if my hair got thicker, well, I didn’t notice. Using the Nixon system was interesting. Nothing happened. It was such an average shampoo and such an average conditioner and the treatment had the effect of 3 water drops on top of my had after shower. I wouldn’t say it is a waste of money because it didn’t do anything…
