              • Q:

                Hi, you did not answer the question properly when another person asked you a question previously and I have the same question. The person asked:
                "I use Nioxin #4 and the bodifying foam. Do I apply this product last? Do I massage it on my scalp?? Can I comb it through my hair as I do the bodifying foam?"
                I also use system 4, shampoo, conditioner and scalp treatment. Do I use this after applying the scalp treatment, or instead, or in combination with the scalp treatment, or how? Also, I was recommended the Nioxin system by my hairdresser and was told to switch the systems every so often so that the product doesn't stop working, so I recently switched to system 3, the scalp treatment in system 3 is not the same as in system 4, it is in a form of a spray, whereas in system 4 it is a foam, why is that? and does the spray have the same effect as the foam? thank you!

                  A:

                  The Nioxin Diamax Treatment is used immediately after you apply the Scalp Treatment. Diamax is a cosmetic thickener that strengthens the roots and hair with proteins. It is not necessary to switch system kits. A consultation tool can be found here:
                  http://s7d5.scene7.com/is/image/Ulta/Nioxin_ConsultationTree

                  It is best to stick with the system kit that fits your particular needs; the difference between Nioxin System 3 and 4 is, System 3 has a liquid Scalp Treatment and System 4 has a foam containing a sunscreen for scalp protection. Both Scalp Treatments are the same strength.

                Does the product permanently increase the thickness of your hair or is it only temporary once applied?

                  A:

                  Diamax does have an accumulative effect, meaning the results gradually get better and better with each use. However, if one stops using the product, eventually the results will fade away. The product can be used on wet or dry hair.

              • Q:

                For the last few weeks i have been wearing my natural hair gel back or gel up, to avoid using heat. But, I have been advised to used this product for my thin edges and my thinning crown. Now that I just start using this product. Can I still saturate my hair with this in addition to using the gel for the updos or ponytails?

                  Yes, this product can be used daily on wet or dry hair and on hair of all textures. It is especially ideal for fine and thin hair, because it works to increase the thickness of each hair strand for the appearance of fullness and volume.
