Am a Nioxin convert
I started using all Nioxin 3 products one month ago; shampoo, conditioner, scalp treatment, volumizing thickening spray and extra hold hairspray. Since I use them all together, it's hard to say specifically if one of the products works or doesn't. In my honest opinion, the Nioxin line has improved t...

Amazing
Hair Type Straight Hair
I bought this for my dad earlier this year with not much expectation. He had a bald spot around an inch and a half in diameter and it's gone now. The missing patch is no longer there. Since he has found a lot of success and shared it with other family members, we no longer have the bottle. My uncle took it with him and it was given to him with around 2/3 remaining. That's still a lot of product, considering it's been half a year. You don't need to replace the bottle that often. I recommend this product!
I would recommend..

I took the hair quiz on the Nioxin website and the recommended products are Hair Fall Defense Shampoo, System 4 Conditioner, Hair Fall Defense Serum, System 4 Leave on Treatment, Hair Booster Serum and I've been using Diamax Hair Thickening Serum. In what order would I apply these products?
- Asked by Rena
- Official Answer By Nioxin - Brand EngageThank you for taking the Nioxin expert hair consultation quiz! This is a great first step to identifying the best products for your hair concerns. The quiz often suggests all the Nioxin products that could be a potential fit. We don't recommend starting all of them at once. To begin, we suggest focusing on the shampoo and conditioner recommended for you. • Start daily with the Hair Fall Defense Shampoo along with the System 4 Conditioner followed by the System 4 Scalp Treatment. After using the these products consistently for a few months, you can then consider adding an extra product. like Diamax Advanced Thickening Treatment. Diamax is specifically designed to boost hair thickness and density, giving you thicker, fuller-looking hair instantly. This product is a great addition for increasing the thickness of each hair strand, which complements the System Kit's benefits. If you have any questions about the products or want to discuss your results in more detail, please feel free to reach out. 800-935-5273Was this answer helpful to you
- Q
Are all these 3 products FDA approved?
- Asked by Coop
- Official Answer By Nioxin - Brand Engageno, Nioxin products as a whole are not FDA approved, because the FDA does not "approve" cosmetic hair care products like shampoos, conditioners, or cosmetic serums before they hit the market. However, there is an important distinction to make regarding ingredients and specific products: The classic Nioxin System Kits (Cleanser, Scalp Therapy, and Scalp & Hair Treatment) and their cosmetic serums (like the Night Density Rescue or Hair Fall Defense) are classified by the FDA as cosmetics. The FDA regulates cosmetics to ensure they are safe for consumer use and properly labeled, but it does not evaluate or approve them for efficacy. These products do not claim to medically regrow hair; instead, they are formulated to clear away follicle-clogging sebum, strengthen the hair strand against breakage, and improve the scalp environment so existing hair looks and feels thicker. If you are looking for a medical cure for hair loss that carries direct FDA approval for hair regrowth, you would look specifically for treatments containing active Minoxidil. If you are looking to optimize your scalp health, reduce hair breakage, and maximize the density of the hair you currently have, Nioxin’s cosmetic systems are designed precisely for that.Was this answer helpful to you
