## Questions & Answers

**Q: What is the difference between Nioxin system 4 & 6 conditioner?**
A: Great question I would be happy to assist you with. Nioxin System 4 is for color treated hair only. Nioxin System 6 is for chemically treated hair meaning permed or lightened with bleach. I hope this answers your Nioxin questions today. Have a beautiful hair day!

**Q: Which one ( 4, 5 or 6) should I buy...? I have fine , high lighted hair with with hair loss and my scalp is itchy**
A: Hi Tina. I have color-treated hair (not bleached) with light thinning and was using #4 for more than 10 years. I switched a couple years ago when I discovered #6 and felt it would offer more protection and hopefully even better results. Both #4 and #6 have UV protection, which is a plus. Either one would be good, but I don't think I would choose #5. I hope this helps.

**Q: Is the Nixion shampoo ok to use for hair with extensions?**
A: Thank you for contacting Nioxin. We value your brand loyalty.
Nioxin System 4 Cleanser can be used with extensions.

**Q: Does this product have an expiration date?**
A: No. It does not.
