      Comments about Nioxin System 4 Cleanser:

      New packaging is usually a dead giveaway that something has changed. Sure enough, they have reformulated the shampoo. I have used this for years with no complaints, but will now be looking for a new shampoo. This new formula is horrible. It doesn't lather well and It doesn't make my hair feel "clean". No matter how much I rinse, it leaves behind a residue that makes my fine hair feel heavy, coated, and weighed down. It builds up badly. It actually made my hair fall out even more than before. After using this for a few days, I had to use a clarifying shampoo to strip everything out of my hair. I don't understand why these companies feel the need to change things when they don't need changing. So long Nioxin.

        My hair has been shedding a LOT the past several months and I was beginning to notice that it was looking thinner. I started using this a few weeks ago and I'm losing less hair. My hair also feels thicker and fuller. I like how it makes my scalp feel very fresh and clean. I plan to continue using it!

          Ok this shampoo basically changed my life. I live in Michigan so a good part of my life is spent with the furnace and car heater drying my hair out like crazy and the most frustrating and saddening thing is how staticy, flat and dry my hair was for years. I have a closest full of shampoos I bought to try and help this and never found anything that worked until this one! My hair is so much thicker, never has static and has texture. Love, love, love.

              Comments about Nioxin System 4 Cleanser:

              I'm very skeptical when it comes to products that claim to help with hair loss so I wasn't expecting this product to actually help, but it did within two weeks of usage. My hair was falling out in huge chunks due to high stress prior to switching to this system. Only problem is I don't see any baby hairs and my hair is still growing out thin and is light brown at the roots (my natural hair color used to be dark brown/black).

                Great product but a little drying to the hair. No problem for me since I add moisture after I shampoo and condition my hair anyway. The product works as advertised and my hair has stopped shedding.

                For years my hair wouldn't grow but I started using this and a year later my hair is finally
                Long almost down to my butt which is amazing being that it was up to my shoulders for so long. I truly believe in this product and recommend it to anyone looking to improve their thinning hair. I believe it cleaned my scalp for hair growth. I use this and the pureology condition and so far, I'm in love!

                    Hi I thinning hair is heritary for me but also under a lot of stress. I have been using Number 6 for several years and it seems to be slowing the thinning. I have noticed lately some more thinning in the front. And I now color my roots occasionally. Should I use number 4 or any other product? Help please!

                      A:

                      The number 6 is great for chemically treated hair, the number 4 is for color treated hair. If you perm or chemically straighten your hair the 6 is great for you. If you just color it, I would use the 4.

                      A:

                      Nioxin System 4 is formulated for noticeably thinning, fine, chemically treated hair. System 6 is specially designed for noticeably thinning, medium to coarse, natural or chemically-treated hair, and might be a better choice for you. I would stick with System 6, but add the Hair Booster to help with the problem areas.

                      I would stick with the number 4, but I would consider using the Hair Booster as well. Nioxin Hair Booster is an intensive leave on booster for areas of concern, such as the hairline or crown. Dual action technology for protection accompanied by sensation. It is for specific area that additional attention.

I would ask your stylist to add a clear glaze to seal in the color and prevent fading.,Because of the size of the molecules in red hair colorant, I would ask your stylist to add a clear glossing service to your hair color to help seal in your color. To help with the with dryness I would recommend 3D Intensive Deep Protect Density Mask. Thank you

                      Hello,
                      We don't recommend alternating other shampoos and conditioners with our products. Our products are meant to clean the follicle from environmental debris, sebum, and refresh the scalp. Alternating products prevents the follicles from being opened and promoting hair growth.

                    I had a balayage and ombré done last December and a retouch in March and began noticing that my hair started falling out like crazy around July, or so, and it's gotten a lot more thin and dry. I have noticed a balding spot in the front, middle section of my upper forehead and I'm afraid it won't grow back. I was recommended Nioxin 4 for chemically-treated/thin hair to see if it would help. What would be the recommendation as far as which shampoo/conditioner and treatments I should use? (My hair loss may be caused by stress and it may be hereditary.)

                  • Q:

                    My hair began to thin due to 2 family deaths within 3 months and High BP medications. Nioxin 4 was recommended as I have fine, color treated hair. I am beginning to freak out as unsure if doing correctly. One Q&A (Ulta) said not to use the daily scalp treatment if using minoxidal. This Q&A says to use both. Also the other Q&A said to use a scalp "something" cleanser instead of the shampoo in #4. Which is correct? Also, do I have to daily wash my hair to see benefits? I typically wash once/week due to curly, frizzy, fine hair. HELP!

                      Hello,

                      I'm very sorry for your loss. I am happy to answer these questions for you. If you are experiencing hair loss and it is hereditary, we would recommend the Minoxidil. However it sound like your hair loss may be due to stress. I would recommend using the system number 4 to help regenerate hair loss. It would be best to use that to help cleanse the follicle to promote hair growth.

                      A:

                      Response from Coty, Nioxin's parent company:

                      "All of our products are cruelty free. We do not perform, nor do we ever commission any third parties on our behalf to perform, testing of our products or ingredients on animals. COTY voluntarily ceased testing finished cosmetic products on animals in 1991, long before the official European ban on such testing in 2004, and we have been actively involved in the research and development of alternatives to animal testing for many years."
