Review: Good stuff. - Excellent product that helps with thinning hair. I am a regular user of Nioxin shampoo and conditioner to help with my thinning hair caused by medical treatment. It isn't cheap but in my opinion, it is worth every penny. It can be used on wet or dry hair. I have only used it after each shampoo before styling.
Review: Really does work! - Yes this product really works. Was recommended it by my hairdresser… so pleased with it.

## Questions & Answers

**Q: Please can anyone tell me if it leaves your hair crispy or stiff.  I have naturally curly hair, not looking for a firm finish,would like a soft bounce**
A: This doesn’t leave your hair in the least bit crispy. I’ve used it for a long time now and my hair feels soft. Don’t use the foam version though as that is definitely crispy

**Q: Do I use this on top of step 3 of the 3 step system?**
A: Initially when my hair loss was at its worst I used all Nioxin products,  the shampoo, conditioner etc. Now my hair loss is not as bad I tend to use just the Diaboost  serum on dry hair to add thickness. This works best for me. Think it’s finding what works best for you.

**Q: Do you leave this on or rinse it off?  One section says leave 3 mins & rinse well, then in another section it says leave in?**
A: I leave it on for about 3 minutes and then rinse and the. One a month I leave it in over night

**Q: Is this the original product?**
A: Yes, definitely. Bought two bottles- they are just the same as my empty bottle which I bought at the hairdresser.

### ⭐⭐⭐⭐ Makes a difference
*by R***A on 10 July 2024*

I love the smell and the difference it made to my hair. I was bought a bottle for Christmas and I have since bought myself a second bottle. I will say though, it doesn't last long and I feel it only gives a temporary fuller, thicker feeling when used. As soon as I have stopped using it my hair went back to looking and feeling fine and lifeless.
