## Questions & Answers

**Q: What is the expiration date of this product being sold by Gold Fulfillment?**
A: I looked it up in frequently asked questions in the Nixon site. The product has a 36 month shelf life. And it is effective for 12 months once opened

**Q: What does200 MI mean?**
A: It's 200 ML (milliliters) which is equal to 6.76 FL (fluid ounces) the amount in the bottle

**Q: Can you use this with hair booster Nixon treatment also?  If so, which first? Or does it matter?**
A: I answered wrong the first time. I shake the bottle and then it foams, and I mix it over my scalp. No more hair loss! Yes, I use it first after showering.

**Q: Does this nioxin system 4 treatment have an spf in it?**
A: Hello, the packaging says it has a UV defense for your hair, but no mention of an spf for your scalp. I am very fair, have very thin baby hair, and live in a high altitude. I haven't had much of a problem and I have used it for about 5 years. I hope this helps. Regards, Ellen
