Hi, I am interested in purchasing the product however I haven't used hair products my entire life with no issues due to my natural oils etc. Would the treatment (step 3 without shampoo and conditioner) still have beneficial effects? Is it recommended to use this product if I rely on natural oils? AND are there any offers for customers like me that only require the one product without the shampoo and conditioner? Thanks, Luke

- Q
Why doesn't Nioxin reformulate their shampoo to omit sodium lauryl/laureth sulfate with it being known that this ingredient isn't really good in the long run for your hair?
- Asked by Cool246
- Official Answer By Nioxin - Brand EngageSodium Lauryl Sulfate (SLS) is defined as surfactant. It is used to clean skin and hair and as emulsifier in cosmetics. In this function, surfactants wet body surfaces, emulsify or solubilize oils and suspend the soil. As such, they can clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away or suspend poorly soluble ingredients in water. Therefore we use it mainly shampoo products. That is a great question. Sulfates have recently gotten a bad rap as being bad for you and your hair. What you need to know is that sulfates are the ingredient that cleanses the hair. One would need to consume a large quantity of them to have negative results. We use only the highest-grade sulfates – which provide cleansing necessary without pulling color or damaging the hair. Optimal levels are contained in our products which leave the hair clean without over drying. We offer a very nourishing formula overall, which is gentle on the skin and hair. The SLS (sulfates) used are in the international regulatory permitted range, they have been tested extensively for decades to ensure customer health and safety. To protect color treated hair we have the Pro-Color Shield technology that prolongs hair color. I hope that this helps. If you have, further questions please call 800-935-5273. The relationship between sulfates and hair color is not straight forward. Most of what we hear is a myths that come from a "sulfate free" marketing campaign or company. Harsh sulfates will most likely always pull color from the hair and cause dryness. Gentle sulfates with the proper formulation of other ingredients will keep hair color in longer than most sulfate free shampoos. Sulfate free shampoos most often do not cleanse the hair thoroughly enough to rid it of dirt, oils, product and environmental debris. This causes more dirt to attach to the hair and the formation of free radicals. Free radicals cause the fading of hair color. The appearance of a sulfate in a shampoo does not automatically determine the "safeness" of the product. I hope that this helps. If you have, further questions please call 800-935-5273Was this answer helpful to you
