What is the expiration date of this product being sold by Gold Fulfillment?

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

What does200 MI mean?

It's 200 ML (milliliters) which is equal to 6.76 FL (fluid ounces) the amount in the bottle

Can you use this with hair booster Nixon treatment also? If so, which first? Or does it matter?

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.

Does this nioxin system 4 treatment have an spf in it?

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
