NIOXIN 3D Intensive Deep Protect Density Treatment

Q: Do I use this with the three other products in the 3 step treatment of shampoo, conditioner then hair & scalp treatment ?

My hairdresser who has been trained to use these products advised me to use it. The 3 other products are for the scalp, this intensive care is apparently for the hair. It does make a difference and the hair feels quite silky to the touch. I wash and rinse the hair, then use the scalp conditioner. I do not rinse it off immediately as I then apply the intensive care just to my hair. I then rinse both off together. After towel drying my hair I apply the scalp and hair treatment . It does not need excssive amounts for the treatment to work really well.

Q: This does not arrive sealed, are these inauthentic Nioxin products?

I've bought this listing several times, sometimes the cap has a plastic seal around it that you have to tear off, sometimes it's unsealed. But it's unsealed and unboxed when I buy it in my local salon too, so I can't tell whether it's the genuine article or not. It smells right though...?!

Q: What is the expiry date of this product ?

I think it might depend when you bought it Is there an expectation date on the box or bottle. These are excellent products made with the finest of ingredients and I would imagine they have a shelf life of years. I use mine all the time do it wouldn’t last me years. I use this product all the time you only need a little bit. But I cannot imagine it expiring in use. I buy a new one about every 6-9 months and use every other wash and have never had any problems. Just a little tip it is a very thick product Do I get a few extra used out of it by when you can squeeze no more out I add a little water shake it up and down in the tube and it gives me a few extra uses .
